How I helped design a new lager at the White Horse

Václav Berka explains the secrets of brewing Pilsner Urquell in the upper room at the White Horse, Parsons Green

Václav Berka, senior trade brewmaster, explains the secrets of brewing Pilsner Urquell in the upper room at the White Horse, Parsons Green

I’ve taken part in many beer-related events in the upstairs room at the White Horse in Parsons Green, from tasting porter rescued from a 19th-century shipwreck to making a presentation on my historical beer heroes, but I never thought I would one day be helping to brew a lager there. Even more unlikely, this lager was made with genuine Plzeň well water – and it stood a fair chance of going into large-scale production.

The event was organised by Pilsner Urquell, the invitation came from Mark Dredge, to whom I am extremely grateful for such a fun day, it was called the London Brew-Off, and it involved three teams of beer enthusiasts, each put in charge of a 20-litre Speidel Braumeister brewing kit, handed four kilos of ground Czech malt, pointed to bags containing a selection of other speciality malts and eight or ten different hop varieties, and told to think up a recipe for a pilsner that would be good enough to go on public sale, using those ingredients, and then brew it. Our raw, hopped wort would be cooled, then have proper Pilsner Urquell yeast added, and be taken away for fermenting and lagering and, finally, bottling. On Tuesday July 15, that is, just over six weeks later, all the lagers the teams had made will be test-tasted, and the best one will be put into full-scale production – 30 hectolitres, 5,270 pints by Windsor & Eton Brewery, ready for the White Horse’s Euro Beer Fest in September.

Doing my bit for the Surrey hop-growing industry

I’ve been invited on plenty of brewery visits over the years, but never before has the invite come with the request: “Please bring wellies and a spade.” This, however, was a field trip in a considerably more literal sense than normal: to the two and a half-acre field right opposite the Hogs Back brewery in Tongham, just outside Farnham in Surrey, to witness – and take part in – a historic event: the first planting of the Farnham White Bine hop variety in its native soil since the last bines were grubbed up 85 years ago.

This is not just, however, a footnote in Farming Today magazine: this is, according to Hogs Back’s chairman, Rupert Thompson, an important step towards increasing the “localism” aspect of the brewery’s products. Once the new hop ground (the proper Surrey name for what elsewhere are called hop gardens or hop yards) is producing a healthy crop, those hops can then be used to flavour the beer being brewed just yards away: Surrey’s own hop variety, grown in Surrey, to produce Surrey beers.

A century and more ago, Surrey was an important hop-growing area, and for a very long time, up to at least 1850, Farnham White Bines were the most favoured hop variety in the land, described as having “a most delicate flavour”. Richard Bradley, Professor of Botany at the University of Cambridge, writing in 1729, called Farnham “the first capital Town for Hops in Britain.” Three years earlier, the Reverend John Laurence, in a book called A New System of Agriculture, said: “The noble Plantation of Hops at Farnham where for Regularity and Exactness the appear like Woods and groves cut into Vistaes is a beautiful Sight.” Arthur Young, the agriculturalist, said in 1798 that “they grow very large quantities” of hops around Farnham, and hop grounds were let in the district “from £3 to £9 an acre, which last price is very great.” In the second half of the 19th century, Kentish hops overtook those from Farnham in favour, but Farnham hops were still ranked second in quality after those from East Kent in 1890, and even in 1909, George Clinch could say: “The Farnham hops have long been famous for their excellent quality.”

In 1886, Surrey had 2,937 acres of hop grounds: half the size of the Sussex hop crop and a third that of Hampshire, but more than either Hereford or Worcester. Disease – to which hops in general and Farnham White Bines in particular are prone, especially downy mildew – hammered the Surrey industry, and the county’s own hop disappeared from its homeland in 1929, to be replaced by more disease-resistant varieties. But even in 1959, there were still 1,879 acres of Surrey hop grounds, which made up 9.2% of all the land then given to hop cultivation in Britain. The collapse of the industry since that time is encapsulated in one telling statistic: the planting of hop bines at Tongham this week doubled the number of existing hop grounds in Surrey.

Before the planting on Monday, Rupert Thompson said: “It will be wonderful to look out from the brewery and see the raw materials we use growing in the next-door field – that’s local! That is part of what makes the craft brewing revival so exciting.” Right now all you can see is a muddy field with, if you look carefully, row after row of angled pieces of metal sticking a few inches out of the ground, all carefully spaced one foot apart. Each marks where a hop plant was planted by a small but enthusiastic squad of helpers, including me. But in a few weeks, once the hops start to grow, the trellising will be going in: and a couple of months after that, the field should be a magnificent sight: two thousand or so hopbines (slightly fewer than half Farnhams, the rest the American variety Cascade), leafy and green, climbing 15 feet or more into the Surrey sky.

Why Shakespeare liked ale but didn’t like beer

The trademark registered by Flower’s brewery of Stratford upon Avon

An old friend of mine gained a PhD in the relative clauses of William Shakespeare, with particular emphasis on the later plays. Ground-breaking stuff, she told me, and I’m sure that’s true. My own contribution to Shakespearian studies is rather less linguistic and more alcoholic: I seem to be the first person in centuries of scholarly study of the works of the Bard of Avon to point out that his plays clearly show Shakespeare was a fan of ale, but didn’t much like beer.

To appreciate this you have to know that, even in the Jacobean era, ale, the original English unhopped fermented malt drink, was still regarded as different, and separate, from, beer, the hopped malt drink brought over from continental Europe at the beginning of the 15th century, 200 years earlier. It was made by different people: Norwich had five “comon alebrewers” and nine “comon berebrewars” in 1564. In 1606 (the year Macbeth was performed at the Globe theatre) the town council of St Albans, 25 or so miles north of London, agreed to restrict the number of brewers in the town to four for beer and two for ale, to try to halt a continuing rise in the price of fuelwood.

This separation of fermented malt drinks in England into ale and beer continued right through to the 18th century, and can still be found in the 19th century, though the only difference by then was that ale was regarded as less hopped than beer. Even in Shakespeare’s time, brewers were starting to put hops into ale, though this was uncommon. In 1615, the year before Shakespeare died, Gervase Markham published The English Huswife, a handbook that contains “all the virtuous knowledges and actions both of the mind and body, which ought to be in any complete woman”. In it, Markham wrote that

“the general use is by no means to put any hops into ale, making that the difference between it and beere … but the wiser huswives do find an error in that opinion, and say the utter want of hops is the reason why ale lasteth so little a time, but either dyeth or soureth, and therefore they will to every barrel of the best ale allow halfe a pound of good hops

.

The book’s recipe for strong March beer included a quarter of malt and “a pound and a half of hops to one hogshead,” which may be three times more hops than Markham was recommending for ale, but is still not much hops by later standards, though Markham said that “This March beer … should (if it have right) lie a whole year to ripen: it will last two, three and four years if it lie cool and close, and endure the drawing to the last drop.” In his notes on brewing ale, Markham said: ” … for the brewing of strong ale, because it is drink of no such long lasting as beer is, therefore you shall brew less quantity at a time thereof …. Now or the mashing and ordering of it in the mash vat, it will not differ anything from that of beer; as for hops, although some use [sic] not to put in any, yet the best brewers thereof will allow to fourteen gallons of ale a good espen [spoon?] full of hops, and no more.”

Markham was writing in the middle of a battle fought for more than two centuries to try to keep ale still free from hops, and separate from hopped beer. In 1471 the “common ale brewers” of Norwich were forbidden from brewing “nowther with hoppes nor gawle” (that is, gale or bog myrtle). In 1483, the ale brewers of London were complaining to the mayor about “sotill and crafty means of foreyns” (not necessarily “foreigners” in the modern sense, but probably people not born in London and thus not freemen of London) who were “bruing of ale within the said Citee” and who were “occupying and puttyng of hoppes and other things in the ale, contrary to the good and holesome manner of bruying of ale of old tyme used.” Continue reading

India Session Ales – tremendous new trend or oxymoronic category fail?

“All the IBUs, half the ABV” is how the American beer writer Brian Yaeger describes the newest (?) beery trend in the United States: the “India Session Ale”.

10 Barrel ISAAs you’ll have gathered, the ISA is meant to have the flavours of an American-style IPA, but at a more “sessionable” gravity. “Sessionable” is in the eye of the beer holder: I’d curl my lip at any beer over 4.2 per cent describing itself as “sessionable”, but to many Americans the term means anything under 5 per cent. However, what worries me most is the idea that a beer with 50 IBUs, and hopped with at least six different and powerful varieties, including Warrior, Columbus, Citra, Simcoe, Amarillo and Chinook, even if it’s only 3.5 per cent alcohol, like Ballast Point of California’s Even Keel can in any way be regarded as a session beer. Indeed, at least one “India Style Session Ale”, from the 10 Barrel Brewing Co in Oregon, is 5.5 per cent ABV.

As I wrote in this space nearly four years ago, I love session beers, but to me an essential part of what makes a good session beer is its restraint. To quote myself:

A great session beer will not dominate the occasion and demand attention … A good, quaffable session beer should have enough interest for drinkers to want another, but not so much going on that they are distracted from the primary purpose of a session, which is the enjoyment of good company in convivial surroundings.

I’ve not, unfortunately, had the opportunity to try any of the India Session Ales (also known as “American session ales”, “Session IPAs” and “Light IPAs”) Brian Yaeger talks about in his piece, but in April I did get to try something I suspect may be similar, DNA New World IPA, the collaboration beer made by blending concentrated “essence of Dogfish Head 60-minute IPA” shipped over from Delaware with beer brewed at the Charles Wells brewery in Bedford.

How long have English brewers been using American hops? Much longer than you think

How long have British brewers been using American hops? Far, far longer than you might have guessed: for around two centuries, in fact.

HopsThe earliest evidence I’ve collected so far of hops from the United States in England is from exactly 196 years ago: May 1817, when the Liverpool Mercury newspaper carried a notice of the arrival in the city of a ship from New York, the Golconda, carrying 417 bales of cotton, 319 barrels of flour, 1,322 barrels of turpentine – and two bags of hops. Rather more came across the Atlantic a few months later, in November, when two ships arrived, the Pacific from New York and the Triton from Boston, with cargos including 49 bales of hops and 30 bags of hops respectively. An even larger consignment, 185 bales (a bale being 200 pounds), arrived the following month, December, from Boston on board the ship Liverpool Packet.

Not coincidentally, these imports of hops from the United States were arriving in Britain right after the famous (to climatologists) Year Without a Summer of 1816, itself the result of the biggest volcanic eruption in recorded history (with the possible exception of the putative proto-Krakatoa), when Mount Tambura in Indonesia blew up on April 10 1815 with a roar heard 1,600 miles away, sending 50 to 100 cubic kilometres of rock into the air and dumping tens of millions of tonnes of sulphur and ash into the stratosphere via a column of smoke and fumes 27 miles high, covering the northern hemisphere in a sulphate veil. Temperatures in North America and Europe dropped by as much as 3C for at least two years, rainfall rose by as much as 80 per cent, and agriculture was badly hurt.

The year after the eruption, the hop harvest in Britain, in particular, was hammered. Newspapers from September 1816 onwards engraved a picture of misery. The Hereford Journal reported that locally “the hops have nearly all been destroyed by the inclement season.” At Worcester fair, the Morning Post said, “there was not a pocket of new hops”. At Stourbridge Fair, just outside Cambridge, normally one of the country’s biggest hop marts, “the supply of hops was very small, not more than half a load.” In Farnham, Surrey, the hop cones were “uncommonly small”, and the harvest was set to be no more than a quarter of its usual size. At Weyhill fair in Hampshire in October just over 700 pockets of hops were on sale, down from 3,000 the previous year. Continue reading

The Graveney Boat, a hop history mystery

In the history of brewing in Britain, the Graveney Boat is an archaeological anomaly almost as great as finding the skeleton of an Anglo-Saxon warrior with a hole in his skull that could only have been made by a 17th-century musket ball.

The boat – actually a clinker-built cross-channel cargo vessel, reconstructed as some 44 feet (13.6 metres) long, 11 feet (3.4 metres) wide and just three feet  (one metre) in draught – was abandoned more than a thousand years ago. It was discovered in 1970 under six feet of soil, during the widening of the Hammond Drain, a silted-up ancient natural water course linking Graveney village, a small settlement near the coast between Faversham and Whitstable in Kent, with the Thames estuary.

Dendrochronology suggests the Graveney Boat was about 55 years old when it was abandoned, since it was built from oak timbers cut in the mid-890s, and it had apparently been left to settle into the mud some time close to 950AD. When archaeologists analysed the boat and its immediate area, searching in particular for plant remains, they found evidence that pointed strongly towards it having carried a cargo of hops.

The Graveney Boat being excavated in 1970

Yet at the time the boat was stuck up a Kentish creek, (at a period when there was still a separate Viking King of Northumbria, contending with the King of England), English brewers were not using hops to flavour their ale – or at least, there is no good evidence at all that they were doing so. Hops stay unmentioned in the history of English brewing (apart from one brief and almost equally mysterious pop-up in the 12th century, to which we will return) until the 1500s, almost 400 years later, when immigrant brewers from the Low Countries started making the upstart Continental hopped drink bere, a rival to unhopped traditional English ale. So why were there hops on board the Graveney cargo boat?

So what DID Pliny the Elder say about hops?

What did Pliny the Elder actually say about hops? Not what you’ve been told, probably – and quite possibly he said nothing about hops at all.

Thanks to the chaps at the Russian River brewery in Santa Rosa, Sonoma County, California, who named their extremely hoppy, strong “double IPA” after him, the Roman author, lawyer and military man Gaius Minor Plinius Caecilius Secundus, who died in AD 79 from a surfeit of scientific curiosity after getting too close to the exploding Mount Vesuvius, is now probably better known than at any time in the past 1,900 years.

Russian River named their beer Pliny the Elder because he is supposed to be the first person to mention hops in writing, in his great survey of contemporary human knowledge, Naturalis Historia. (They named an even hoppier, stronger “triple IPA” after his nephew and heir, Pliny the Younger.

The hop, from Leonhart Fuchs’s De historia stirpium commentarii insignes

But the plant that Pliny the Elder wrote about, which he said was called lupus salictarius (which translates as “wolf of the willows”, salix being the Latin for willow tree*) may not have been the hop: there’s certainly no completely convincing evidence in Pliny’s own writings to confirm that lupus salictarius and hops are the same thing.

The first person to identify Pliny’s lupus salictarius as the plant that Italians call lupulo, the Spanish lúpulo, Germans Hopfen and English-speakers hops seems to have been a 16th century Bavarian botanist called Leonhart Fuchs, in a book called De historia stirpium commentarii insignes, or Notable commentaries on the history of plants. But Fuchs (after whom, apparently, the fuchsia is named), had made a big effort to try to match up “modern” plants with those mentioned by classical authors, and may have made a mistake in deciding that lupulo was derived from, and identical with, Pliny’s lupus salictarius. At least one writer has suggested that the word lupulo, far from being derived from the earlier term, may simply be an Italian error for “l’upulo“, via the French for hop, houblon, and nothing to do with lupus salictarius.

What did Pliny actually say about lupus salictarius? He mentions it, briefly, in Book 21, chapter 50 of his Natural History, which is a short section about wild or uncultivated foods. After talking about the wild plants eaten in Egypt, he then says:

Two horsey beers and a short kipple

I know it's nothing to do with the beer, I just like the poster

I was lucky, I think, in having my first pint of Bengal Lancer IPA, Fuller’s latest offering, in the Prince Blucher in Twickenham, where it was in excellent condition: a couple of subsequent trials elsewhere in West London haven’t been quite as good, so to borrow an Americanism, “your mileage may vary.” But I don’t think I’ve ever made such lengthy tasting notes about any beer, a tribute in itself.

The first impression is of a BIG hit of hops on the nose, with passion fruit noticeable immediately. It’s a hop-filled mouthful, with a good oily feel, and one of those beers where you’ll find something different in every swallow. Indeed, teasing apart the different taste strands is one of the pleasures of Lancer: it’s a beer for sitting and appreciating. I was getting a hint of blackberry, something earthy in the background, peppermint, the “signature” Fuller’s orange note (though less strong than in many of their beers), all with honey maltiness underpinning the floral hops and a lovely long follow-through.

I’ve seen the beer criticised as being too sweet, but to me any apparent sweetness is more an artefact of the amount of “high note” hop flavour coming through that anything real, and while the emphasis is definitely on hop aroma rather than bitterness I found it ultimately quite dry: I’d be interested in seeing the attenuation figures. Certainly, if you watch the video available here from Fuller’s, the company’s brewing manager, Derek Prentice, implies it’s a well-attenuated brew.

The long battle between ale and beer

How long did ale and beer remain as separate brews? Most* drinkers, I think, know that “ale” was originally the English name for an unhopped fermented malt drink, and beer was the name of the fermented malt drink flavoured with hops, a taste for which was brought to this country from the continental mainland about 1400. Some might be able to tell you that ale and beer then existed alongside each other as separate drinks for some time: but that eventually ale started being brewed with hops as well, and finally any difference between the two drinks disappeared, with “ale” and “beer” becoming synonyms. But when did that happen?

I used to think that their merger into synonymity was pretty much complete in Georgian England at the latest, agreeing with the historian WH Chaloner, who wrote in 1960, reviewing Peter Mathias’s great book The brewing industry in England, 1700-1830: “By the end of the seventeenth century the terms ‘ale’ (originally a sweetish, unhopped malt liquor) and the newer ‘beer’ (a bitter, hopped malt liquor) had come to describe more or less identical products following the victory of the latter drink.” But as I read more and more, I slowly realised that this was untrue: that in English, “ale” and “beer” maintained differences through until the 20th century that were, ultimately, from their origins as unhopped and hopped drinks respectively (and nothing to do with the modern American habit of referring to all “top-fermented” beers as “ales”, regardless of their histories and origins).

Beer geekery warning: if teasing apart the knotted and tangled threads of brewing history is your bag, stick with me for the next 2,500 words as we range over five centuries of malted liquors and watch meanings mutate: if you’d rather read something contemporary, Rob Sterowski, alias Barm, at I Might Have A Glass of Beer is always an interesting and often a provocative read, and he maintains an excellent list of other beer bloggers as well.

For those of you still with me: here’s a quote on ale and beer from 1912, less than a century ago, from a book called Brewing, by Alfred Chaston Chapman:

“At the present day the two words are very largely synonymous, beer being used comprehensively to include all classes of malt liquor, whilst the word ale is applied to all beers other than stout and porter.”

Why weren’t stout and porter called ales? This is a reflection, 200 years on, of the origin of porter (and brown stout) in the brown beers made by the beer brewers of London, rivals of the ale brewers for 500 years, ever since immigrants from the Low Countries began brewing in England with hops.

A short history of hops

One of the great unanswered questions in the history of beer is why it took 9,000 years or so after brewing began for brewers to start using hops.

Today there are very few beers made without hops. They give beer flavour and, most importantly, they keep it from going off. The shelf life for unhopped ale can be as short as a fortnight or so before it starts to spoil and sour. Hopped beer can last for years. But it took many millennia for brewers to discover this, though they had been using a huge range of other plants to flavour their ale in the meanwhile: the bushy, aromatic moorland shrub bog myrtle, for example, the grassland weed yarrow, the hedgerow plant ground-ivy, even rosemary and sage.

The first documented link between hops and brewing comes from Picardy in Northern France, in 822, where Abbot Adalhard of the Benedictine monastery of Corbie, in the Somme valley near Amiens, wrote a series of statutes on how the abbey should be run. The many rules covered areas such as the duties of the abbey’s tenants, which included gathering of firewood and also of hops – implying wild hops, rather than cultivated ones. Adalhard also said that a tithe (or tenth) of all the malt that came in should be given to the porter of the monastery, and the same with the hops. If this did not supply enough hops, the porter should take steps to get more from elsewhere to make sufficient beer for himself: “De humlone … decima ei portio … detur. Si hoc ei non sufficit, ipse … sibi adquirat unde ad cervisas suas faciendas sufficienter habeat.”

It is important that the Corbie statutes should link hops with beer brewing, because hops had other uses they might have been collected for: to make dyes, for example (brown dye from hop sap and yellow dye from the leaves and cones). The stems can also be used to make ropes, sacking and paper. Thus any mentions in old documents of hops being collected from the wild, or even cultivated, does not mean automatically that the hops were going into beer

But Adalhard’s statutes do not say whether the hops were being used to preserve the beer, or merely to flavour it (the way brewers today dry-hop their beers). Proof that hops were being used the way they are today, as a preservative, does not come for three more centuries, at another Benedictine establishment at Rupertsberg, near Bingen, in the Rhineland. About 1150, Abbess Hildegard of Bingen (1098-1179), mystical philosopher and healer, published a book called Physica Sacra, which translates best as “The Natural World”. Book I, Chapter 61, “De Hoppho”, or “Concerning the hop”, says of the plant: “It is warm and dry, and has a moderate moisture, and is not very useful in benefiting man, because it makes melancholy grow in man and makes the soul of man sad, and weighs down his inner organs. But yet as a result of its own bitterness it keeps some putrefactions from drinks, to which it may be added, so that they may last so much longer.”

By itself this does not prove hops were used in beer, just “in drinks” (in potibus in Hildegard’s original Latin). But in a later chapter, on the ash tree, the abbess wrote: “If you also wish to make beer from oats without hops, but just with grusz [gruit], you should boil it after adding a very large number of ash leaves. That type of beer purges the stomach of the drinker, and renders his heart [literally ‘chest’ or ‘breast’] light and joyous.” Clearly Hildegard knew about brewing beer with hops. The passage also suggests that Hildegard knew about boiling wort, without which just adding hops is not much help in keeping away “putrefactions”.

What probably kept the usefulness of hops from being discovered for so long is that the bittering, preserving resins in hop cones are not very soluble, and the hops need boiling for a long time, around 90 minutes, for what is called isomerisation – the physical change in the hop acids to a more soluble form of the molecule – to take place. Nobody would have boiled hops that long, and thus discovered the isomerisation, without a prior good reason (it takes a lot of fuel, a precious commodity when you have to gather wood by hand, to boil quantities of water for an hour and a half). How was it found out that a good long boil improved both the flavouring and the preserving ability of hops? One possibility is that a dyer, boiling hops to dye cloth, made the discovery that the dye water had a pleasant bitter taste, and told her friend the brewer. But this is just a guess.
