If a 21st century time tripper stepped through the door into the public bar of a London pub in 1900, what would be the biggest surprise? Probably not the sawdust on the floor, or the lack of seating: most likely, I’d guess, the draught ginger beer on handpump.
The existence – and importance – of draught ginger beer in London pubs in the past is one of those uncountable little details of social history that slip past generally unrecorded because they seem so everyday and ordinary to contemporary observers, nobody bothers writing about them. Today’s equivalent would be the bar gun – ubiquitous, observed by everybody who has ever stood at a bar to be served, and mentioned, I’ll bet, in no account of the modern pub, anywhere.
Fortunately, back in the summer of Queen Victoria’s last full year on the throne, one anonymous worker in the brewing industry spotted a reference in the Daily Express to “half-and-half” as a beer mixture, a term not then used for several decades (it referred, in the early years of Victoria’s reign and before, to ale-and-porter), seized the nearest available umbrage at this anachronistic solecism and ran with it for 1,300 words of invaluable exposition on the drinks available from the pumps in a public bar in London, and how they were mixed together, which the Express printed for the education of future generations on page seven of its issue of Thursday August 2, 1900. And hurrah, digitisation and the web means that for a small subscription, 111 years later we can read about what beer mixtures our great-grandfathers drank without having to travel out to the British Newspaper Library in deepest Colindale and whirr through miles of microfilm.
It’s an absolutely fascinating piece, studded with gems – who knew (not me), for example, that in a London “boiled beef house” (a restaurant specialising in serving “a most delicious ‘portion’ of stewed beef done up in a sticky, coagulated, glutinous gravy of surpassing richness”, Google reveals), the accompanying drink of choice was porter? Slow-stewed beef and porter: I’m channelling Harry Champion just thinking about it. Please contact me if you’re now planning this as a FABPOW, I’ll be over to try it out.
It also confirms information from other sources, such as the availability of draught lager in at least some outlets in Victorian Britain, the identification of “ale” and “mild” as the same drink, and the higher status given to bitter, compared to ale and porter.
Below is the article in its entirety, with asides and footnotes in square brackets by me. The picture above is of the public bar of the Dover Castle, 172 Westminster Bridge Road, Lambeth, taken the year after it was rebuilt in 1895, and just the sort of bar being talked about: note the sawdust, the brass footrail (seats were found only in the saloon bar) the ten handpumps (the saloon bar only had one), and the rows of casks on the back bar filled with spirits from Old Tom (sweet gin) to brandy. No pumpclips: these never started appearing until the 1950s. I believe this pub was destroyed in the Second World War, since the site is now occupied by a building of typical late-1940s neo-Georgian style, though it’s still a bar, called the Walrus.
Beers many and various and their mixture
By a member of “The Allied Trades”
Recently in the “Express” a poet, calling himself “The Impenitent”, published some verses on “My Pal”, of whom he said:-
“’Is blooming’ drink is always ’arf-and-’arf.”
When “The Impenitent” has called on members of “The Trade” in London as long as I have he will have discovered that there is no such an article in Metropolitan Licensed Victuallerdom as “Half-and-half”.
Were I Mr Lawson Walton, I should refer “The Impenitent” back to a study of moral philosophy, just as that gentleman recommended it its study to Mr Balfour recently. At any rate, the chapter on “How we Classify”, in Jevons’s eightpenny Science Primer on Logic, would come in handy.
For in those portions of a public-house that cabmen frequent business is done on the “Perpendicular System”, ie, “Stand up, order what you want in plain English, don’t keep the “Express” after you have seen what you wanted to see, pay your money, drink up, and make room for other people.”
WHAT THE PUMPS YIELD
Now at certain houses you can get Lager Beer, drawn from a specially constructed tap, or you may buy “Disher’s Ten-Guinea Ale” , “Bass’s No. 1”, “Allsopp’s Barley Wine”, and such like. But these are extras, and outside of ordinary trade. Usually in the “Public Bar”, otherwise known as the “Four-ale Bar”, of a London fully-licensed public-house, there are six liquids drawn from pumps, viz.:-
1. Ginger beer
2. Porter, called in London “Beer” and in the country unblushingly calling itself “Stout”.
3. Ale, otherwise known as “Four-ale”, “Cold Fourpenny”, “Mild”, “Mild Ale”, &c. In Bristol it is known as “Burton”, but in many large towns, eg Nottingham, no malt liquor is sold at so low a price as 4d per pot (quart).
4. Bitter, called in bulk “Pale Ale”.  [sold for six pence a pot]
5. Stout. 
6. Burton, strictly called “Old Ale” [sold for eight pence a pot].
Now we come to the combination of six articles taken two or more together. We now see how “The Impenitent” has tripped in regard to his “’arf-and-’arf”.
A blend of all the above six articles should, properly speaking, be “Waste”, but there are ways and means of dealing with it, and treating it with egg-shells, and other finings, until it becomes again saleable as “Porter”!
Don’t fight shy of porter at a Brewery Tap, or at one of the famous Boiled Beef houses, or at any place you can trust. And this blending of malt liquors, which is so dear to the Londoner, is said to have given rise to the now meaningless word “Entire”. In days gone by, possibly, “Entire Ales” gave a customer the flavour of a mixture though all drawn from one tap. The word now is a status of respectability, just as is “Member of Tattersall’s”, another phrase with a past [look that one up yourself].
Well a blend of one and two [ginger beer and porter] made “Portergaff”; one and three [ginger beer and mild ale] “Shandy” or “Shandygaff”; one and four [ginger beer and bitter], “Shandybitter”; two and four [the writer made an error and meant "two and three", porter and ale] make “Four-half”. It is a drink not so popular as is generally supposed. It is sold for the most part “in your own jugs” at three-and-a-half pence per pot, though since the extra one shilling per barrel on beer in the present Budget [to help pay for the Second Boer War], a comparatively successful attempt has been made to get four pence per pot for four-half.
Porter is a halfpenny a pot [quart] cheaper. Two [porter] is not often blended with four [bitter] or five [the writer had erred again, and meant "six", Burton] but with six [he meant "five", stout] it makes “Cooper”, a drink rather out of favour. Three and four blended make “Mild and Bitter”. Three [mild ale] and five [stout] are “Stout and Mild”; it is never called “Mild and Stout”; such a phrase would be barbarous. Three [mild ale] and six [Burton/Old ale] make “Old Six” [because it cost six pence a pot]; it might be called “Burton and Mild” but such a term is unusual. Four and five make “Stout and Bitter”, occasionally called “Mother-in-law”. Four and six are “Bitter and Burton”; if you said “Burton and Bitter”, you would probably be served with “Mild and Bitter”, and it would serve you right.
The charge for Nos. 1, 2, or 3 is a penny per half-pint glass, a thick, almost unbreakable article, holding 5 per cent of froth at the top – a profit in itself – and the successor of the old-fashioned pewter throughout nearly the whole of London. Four, five or six cost twice as much.
Blends at one and a half pence per half-pint are sold in a compartment known as a “Six-ale Bar”, or “Private Bar”, where there is a stool or two. In “Saloon Bars” nothing is under two pence per glass – there are a few houses where tankards are still obtainable, for the “boom in public-houses” is happily over and licensed victuallers have to think more about building up a business than they do of getting out of a business at an immediate thumping profit.
There are numerous provincial variations of the various authorised terms. For instance, “Beer” at an officers’ mess means “Bitter” – probably the only sort of malt-liquor kept. But down at the Trent Bridge [cricket] Ground at Nottingham, “Beer” means “Ginger-beer”. Visitors to Nottingham should not fail to try “Botanic”, only don’t let them put too much gin in it.
On the fringes of London there are numerous houses open for travellers during “prohibited hours”. These have made unto themselves a law that during these hours they sell nothing under sixpence a quart, and even during “opening hours’ they do not sell “Four-ale” by itself at fourpence a quart. They foist off “Four-Half” on the unwary. Of course, porter costs less per barrel than mild ale, so there is more profit by selling a quart of “Four-Half” for fourpence than there is in parting with a quart of “Four-Ale” for the same sum.
“Burton” does not all come from Burton-on-Trent. It should really be called “Old Ale”. Some of the very best comes from Edinburgh. Yarmouth, too, sends a lot to London. Indeed, there is a large firm of brewers which does not allow anything coming from Burton to be sold in the houses that are tied to them for “Fine Ales and Black Malt”. This firm makes its own arrangements for supplying “Bitter” from places other than Burton.
VIRTUES OF VARIOUS WATERS
“Fine Ales” means “Four-Ale”. Water for brewing the very best “Pale-Ale”, ie “Bitter”, is the specialité of Burton-on-Trent. London water requires “Burtonising” before it is suitable, but there is good water for the purpose in the immediate suburbs, while at Maidstone, Bishop Stortford, Nottingham, and innumerable other places, there are wells of excellent water for “Pale-Ale” brewing.
Burton water does not come from the River Trent, but from very deep and extremely valuable wells of very hard water. Any sort of water does for brewing anything but the best “Pale-Ale”. Home-brewed ale can still be obtained at Nottingham, but the big breweries are competing very hard against it. At Birmingham the big breweries have nearly knocked home-brewed out of the field.
The “Nut-brown Ale that was famed for its strength throughout the village of Grand Pré” has its English equivalent at farmhouses in Suffolk. Trinity’s “Audit Ale” does not come in everybody’s way. But if you are a friend of the London managing director, and happen to be in the vicinity of Belvedere-road, Lambeth, just a little pint and a half jug all to oneself lets one know what “Old Ale” should be like.

 An 1100OG strong ale brewed at Robert Disher & Co’s Edinburgh & Leith Brewery, Playhouse Close, Canongate, Edinburgh
 This must be the brewery’s top-of-the-range Burton Ale, its equivalent to Bass No 1, and another sign that the earliest beers to be called “barley wine” were strong Burton Ales
 because the biggest seller was the drink called Four-ale
 for an explanation of why, see here
 A clue that as early as 1900 the idea of “stout” as a strong beer was vanishing
 Another stake through the heart for those who insists that “pale ale” and “bitter” are different drinks
 Handpumped draught stout survived in Britain until at least the Second World War, though it was declining by then
 So: in Bristol if you ordered “Burton” you got Mild Ale; in London if you ordered “Burton” you got Old Ale. Same general style of drink, in fact, but the Bristolians were getting a weaker, younger version, the Londoners a stronger and longer-matured ale
 ’E’s ’avin’ a larf. However, such “recycling” undoubtedly went on, with the “waste” going into the Mild after draught Porter finally disappeared
 That was the story many believed: in fact, in the 18th century, “Entire” was the standard term for any brew made from the complete run of mashes on one piece of “goods”, or malt
 The same joking nickname was also given to a mixture of Old and Bitter
 Clearly, calculated short measure has an ancient history
 The distinction between the “public bar” and the “saloon bar” in a pub has now effectively vanished, but for readers from outside the British Isles, and those too young to remember, the “Saloon Bar” was the more upmarket room in a pub, where everything was slightly more expensive than in the Public Bar.
 The period from about 1890 to 1899 when breweries rushed to buy up surviving free houses for fear that they would be locked out of the beer market if their rivals captured all the previously untied pubs.
 From the first arrival of “bitter beer” in the late 1830s/early 1840s to the early 1960s, the pale hoppy brew was the middle-class/officer class drink of choice, while the ‘lower orders” drank, first porter, and then mild ale.
 “Bona fide” travellers were entitled to a drink in a pub at any time, regardless of licensing hours. All you had to claim was that you had travelled at least three miles before you arrived at the pub
 This was the drink sold as “Scotch Ale” or “Edinburgh Ale”.
 My suspicion is that the firm referred to was Courage, in Horsleydown, hard by the south side of Tower Bridge, originally an “ale” brewer (that is, not a porter brewer, but a brewer of mild ale), which took pale ale supplies for its pubs from Flower’s in Stratford upon Avon and then Fremlin’s in Maidstone, Kent before finally buying a pale ale brewery itself in Alton, Hampshire.
 Nottingham still had around 110 own-brew pubs in 1900, part of a still-enormous tradition of home-brew inns and beerhouses across much of the Midlands.
 A quote from Henry Wadsworth Longfellow’s epic poem Evangeline
 The very strong ale brewed at Trinity College, Cambridge
 A reference to the Lion Brewery Co, another of London’s “ale” breweries, which stood on the South Bank where the Royal Festival Hall now is. It looks as if Old Ale was a speciality.
