Charrington Stout quality 1922 - 1925

Charrington was one of the big successes of the interwar years. But even they had to be realistic.

First, the good news. They got 30 of the 80 pubs Whitbread got from the Notting Hill Brewery:

"Interesting Brewery Deal.
It is stated that negotiations have been completed for the sale some 80 public-houses belonging the Notting Hill Brewery Company to Whitbread and Company (Limited), and that some 30 of these have been resold to Messrs. Charrington's Brewery. The deal is said to involve quarter of million sterling, Whitbread and the Notting Hill Brewery are purely London concerns, but Charrington and Co. (Limited) own a business at Burton-on-Trent as well one in London. The Notting Hill Company does not publish its accounts, but Whitbreads and Charrington's securities are held by the public, and reports are issued. Dividends on Whitbread Ordinary Shares have recently been 7 per cent., free of income-tax, while Charrington and Co. distributed 9 per cent, respect of 1918."
Yorkshire Post and Leeds Intelligencer - Monday 11 October 1920, page 12.

80 pubs for a quarter of a million quid: I make that an average of £3,125 per pub. Which doesn't seem that much. Though it is 125,000 pints (or 434 barrels) at 6d a pint.

Interesting that Whitbread is reported to be an exclusively London business. I think they're really referring to just the pub trade because I've seen adverts for Whitbread's bottled beer from all over the country. Charringtons didn't keep their provincial trade much longer:

"CHARRINGTON'S. LTD.
TO SELL ALL THEIR LICENSED HOUSES
Messrs. Charrington and Co., Ltd., the well. brewers, have decided to sell the public houses in various parts of the provinces, and they will concentrate on their London business. Altogether 87 licensed properties will submitted for auction. There are 53 fully-licensed houses, 23 on-beer licences and 11 off-licences, with contiguous properties, as well the Abbey Brewery, Burton-on-Trent, with offices, maltings, cooperage, railway sidings, houses, stores, etc.

In Derby the properties are: Dog and Duck, Haarlem-street, and cottage adjoining: off licence, 61, Church-street; Bedford Arms, Bedford-street Coach and Horses, Mansfield road; Lamb Inn Park-street, and adjoining premises; Boar Tavern Cockpit Hill; and Station Inn, Midland-road."
Derby Daily Telegraph - Wednesday 06 January 1926, page 4.

It was probably the brewery that they really wanted to get rid of, but the pubs would have been uneconomical to supply from their London brewery. None of the London brewers seem to have made a huge success from their Burton breweries. I don't think Truman's ever operated at full capacity.

On with the beer itself. It looks a bit on the weak side compared to the average for a 9d (after 1923 8d) Stout. But the two samples in the 1030's are clearly Porter and not Stout. I think some Charrington's publicans were being a bit naughty and passing off the much cheaper Porter as Stout. I've produced a second set of averages with those two removed.

Now how did it score?

Averages without the Porters:

Pretty poorly. Only two of the eleven examples received a positive score. Some of them sound pretty bad. Unsurprisingly, one of the Porters masquerading as Stout was described as "thin". The average score of -1.08 is pretty bad.

Once again, I'm disappointed by Charrington's performance. Only their Burton Ale has done well so far. I'd definitely advise any time traveller to avoid their pubs.

Charrington Prince's Ale

You may have heard of King's Ale, the beer King Edward VII "brewed" at Bass in 1902. Hell, I've even got to try it. And I've heard of the 1929 Prince's Ale brewed at Bass in 1929. But not a Prince's Ale brewed at Charrington in London.

It was brewed in 1932 and made the newspapers: 


"THE PRINCE SEES BEER MADE
Surprise Visit to East End Woman
The Prince of Wales spent over four hours in the East End of London.

The Prince began his tour by making a two hours visit to Messrs Charrington's brewery in Mile End Road, where he saw many of the processes of beer making.

He then drove to West Ham Town Hall, where he was received by the Mayor, Alderman Scolding. Afterwards the Mayor, Town Clerk, and the Prince set out on tour of West Ham.

The first call was at Park Place, a quiet little street off the busy Stratford main road. The Prince got out of his car, went over to one of the little old cottages, and knocked at the door. A woman opened it and the Prince said, "May I come in, please ?"

The woman drew back and the Prince entered, to see the occupier of the house, Mrs Livesey, sitting by the fire nursing her baby and washing her feet.

A Little Talk.
"Immediately I knew it was the Prince of Wales," Mrs Livesey told a reporter."I was never so surprised in all my life. I could do nothing, because I was washing my feet, so I asked the Prince if he would go upstairs. He went up and looked all over the upper floor. Then he came down and had a little talk with me."

After seeing the conditions in the old parts of West Ham, the Prince was taken to the council's Manor Road housing scheme.

"He was surprised by some of the things we showed him," the Mayor told a reporter. "The visit originated in a conversation I had with the Prince when we saw some boys in boxing competition in West Ham last year. He told me then that he wanted to see something of how our people lived. " At the end of his tour I asked him what he thought, and he replied, "'I have seen exactly what I wanted to see."""
Evening Telegraph - Wednesday 16 March 1932, page 9.

You can see from this map of the 1890's that Park Place was no more than an alley:


This aerial photo from 1952 gives an idea of what the area looked like. The corner next to Park Place has been demolished and replaced by some sort of yard:

http://www.britainfromabove.org.uk/image/EAW043559

Here are a few more details about the Prince at Charrington:

"PRINCE OF WALES BREWS BEER
MAY BE WORTH £60 A BOTTLE
SURPRISE VISIT TO HOMES
Beer which was brewed by the Prince of Wales during a visit London brewery will be Jealously guarded for over 30 years, and may be worth £60 a bottle.

The beer was brewed by the Prince when he paid an informal visit to Charringtons Brewery in Mile End Road. E. He consented to "mash" a special brew, and, watched by number of employees, operated the controls which started the "mashing."

This special brew will probably be put away mature for a long time. It will then be bottled, and some will be sent to the Prince. Other bottles will be distributed privately. The beer may become as famous the "King Beer" which was brewed by King Edward when he visited Burton-on-Trent in 1902, and some of which, when auctioned for charity, realised £60 a bottle."
Gloucester Citizen - Wednesday 16 March 1932, page 8.

£60 a bottle was a huge amount back in those days, when you could get a pint of Mild for 6d.

Now here's a bold claim:

"ONE OF THE STRONGEST EVER BREWED
The "Prince's ale "— brewed by the Prince of Wales when he visited Messrs. Charrington’s Brewery, Mile End Road, E., on March 15 - has turned out a great success.
It is classed one of the strongest beers ever brewed, and already has the smoothness characteristic of high-class English ales.

The brew is not for sale, and will be matured for at least another two years before any of it is available for privileged consumers.

So is the gravity that it is estimated that the duty will amount to £13 or £14 barrel."
Portsmouth Evening News - Friday 27 May 1932, page 11.

I felt obliged to work out the gravity based on the duty. In 1932, the duty on a standard barrel (36 Imperial gallons with an OG of 1055) was £6 14s. According to my calculations, duty of £13 a barrel would mean a gravity of 1107 and of £14 1115. So pretty damn strong. Though obviously not so much by modern standards, where beers can be over 20% ABV.

If they really let it mature for two years of more, the Prince of Wales would have almost been king by the time it was released. When his father died in 1936, he was briefly king before abdicating. Maybe that's why I've not heard of this beer.

Cannon Brewery Stout quality 1924

Not long to go now. Especially when there are as few analyses as for Cannon Stout.

I've always imagined Cannon as a relatively small brewery. I may have to review that after seeing how profitable they were. During the 1920's, their profits were larger than Whitbread's of Barclay Perkins, who brewed around 500,000 and 300,000 barrels respectively. Either they were making a huge profit per barrel, or they were brewing a couple of hundred thousand barrels a year. I'd be inclined to go for the latter.

In the table below I've fiddled slightly with the dividend percentage. This is why:

"Brewery Capital Repaid.
Here is further evidence of the prosperity of the brewery trade. In 1910 the capital of the Cannon Brewery was written down from £3,000,000 to £2,350,000, and now it is proposed to restore to the former figure by the capitalisation £650,000 of undivided profit. This will give holders of the Preferred Ordinary one new £2 10s for every share held, and holders of the £25 Deferred three new £25 shares for each Deferred share held. Profits at £420,930 compare with £352,170, and the available balance is £605,533, against £509,712. The Deferred shares, which are privately held, receive a dividend and bonus of 36 per cent., tax free — the same as for each of the previous four years."
Aberdeen Journal - Thursday 21 March 1929, page 13.

The official percentages given from 1919 to 1928 are on the reduced value of the shares, which was 25% of their original value. I've given then as this figure divided before, so that it reflects the original share capital. It makes the figures clearer.

The owners obviously decided to cash in, because in 1930 Cannon Brewery was sold to Taylor Walker. I can see why they'd have been keen. The place was a gold mine. It must have remained profitable because it didn't finally close until 1955, decades after the takeover*.

That's enough financial crap. On with Cannon's Stout. It's a bit weak for an 8d Stout (9d until 1923), coming in about 4 points below the overall average of 1053, and 0.5% below average ABV. How did it score? Take a look:

Not much I can say about such a small sample size. One pretty good one, the other pretty crap. They perfectly cancel each other out, leaving an average score of zero. Which was typical of the overall standard of Cannon Stout? Was it the good one or the bad one.

Time-travelling advice: plumping for Cannon Stout is at your own risk. I can't make any further recommendation.

Ill-conceived twaddle

You find weird stuff in the letters pages of newspapers. Sometimes the assertions they contain are, well, total bollocks. You wonder why on earth they ever got printed.

This is a good example of that category.
"Sir.—I read in your issue of the 23rd inst. a letter from Mr. J. Simpson, of the Yorkshire Brewers' Association, and have some idea that all has not been stated. Recently I read in your columns the speeches of the brewers on the occasion of their meeting in Leeds. Financially it was inferred that things were in a bad way, but remarkably enough. I read in the same paper that Messrs. Whitbreads had paid a dividend of 25 per cent, and added considerably to their reserve funds. This led me to consult the share market column, and it is perhaps truthful to say that, judging front the price of brewery shares, there is no industry in this country which pays so well and regularly as breweries. They are making money "hand over fist" as the saying goes.

Day by day the prices of shares rise, and if anyone is a bit sceptical on the point, let him look at the share market and find the price of a £1 share. If a "free house" is for sale, most extravagant prices are offered by breweries for its purchase. To restore dilapidated public-houses large sums can readily be found. Corner sites in new building areas are secured and permitted to lie dormant for years awaiting the time when a licence is possible.

Some breweries advertise that their beer is brewed from pure malt and bops: others do not commit themselves. No brewer, however, advertises that his beer brewed from British malt and hops. Truth tell. South American barley and Continental hops find their way into the brewery vat. The distillers recently sent a protest to the Chancellor and promised that if he would reduce taxation on whisky they would use 30 per cent. British malt. The position appears to be that there is nothing British in our stimulants except the water.

The cost of brewing a gallon of beer is under 1.5d., and the price at which this gallon is unloaded on the tied landlord ensures that whatever comes or goes, the brewery will reap its tremendous and customary profit. This is why there are no poor brewers in this country. The "tied" landlord demands our help, not the brewer. Heavily rented and rated, with a large sum to provide for a licence, it is remarkable how he survives.—Yours, etc., P.E.H."
Yorkshire Post and Leeds Intelligencer - Tuesday 26 April 1932, page 6.

He makes three points: that breweries were making huge profits; that British beer was brewed almost exclusively from foreign ingredients; that beer cost 1.5d per gallon to brew.

I'll concede that breweries some breweries were making reasonable profits. But the number of takeovers of long-established firms in the 1930's reveals that others were struggling. The claim that Whitbread declared a 25% dividend in 1932 just isn't true. The dividend on the Ordinary Shares was 14%. A pretty decent return, but nowhere near 25%.

British beer hadn't been brewed from 100% British ingredients for getting on for hundred years, WW I excepted. There was a simple reason: British agriculture couldn't produce the quantity of malt and hops required by the brewing industry. That said, the majority of ingrendients were still home grown. The proportion of malt made from foreign barley was rarely more than 20% of the grist.

The last claim is particularly crazy. And demonstrates how little the author knew of the industry. Luckily I've plenty of material to back me up. Because some brewing records include costs. Let's take a look at one, shall we?

This is from a Courage brew of 1st January 1932. It's a parti-gyle of Burton and Mild Ales.

All the beers of the parti-gyle averaged a gravity of 1037.8 and there were 1,516 barrels in total. As well as the price per barrel of each beer, the costs are also broken down by ingredients and tax:

Costs of a Courage brew of 1st January 1932

ingredients + duty price per barrel 1242.41
ingredients + duty price per gallon 34.51
Source:
Courage brewing record held at the London Metropolitan Archives, document number ACC/2305/08/259.


The ingredients alone came to more than 3d per gallon. If you include the duty, which is surely part of the cost of brewing, the price jumps up to more than 34d per gallon. So the letter-writer was wrong by more than a factor of twenty. And that's for a beer several points below the average gravity of 1042.5*.

I can also see whence the ingredients used in this batch came from. The only identifiably foreign material are 18 quarters of malt from Californian barley. That's from a total 178 quarters, so just about 10%.

So pretty much all bollocks, that letter.

Not quite as good as last time. But still a good time to buy Porter! or Numbers!

Barclay Perkins Bookstore

Nürnberg Winterbier and Sommerbier 1886-1887

I'm slowly ploughing my way through the 1903 edition of "Chemie der menschlichen Nahrungs- und Genussmittel". It has over 1,000 analyses of beers, mostly German but with examples from most major brewing countries.

I've already harvested the analyses from a couple of earlier editions, which means there are only 100 or so I need to collect. To add to the 20-odd thousand in my main gravity spreadsheet. It's getting to be quite a collection. Which is sort of the idea.

To quickly recap, in the 19th century Lager was split into two main types, Winterbier and Sommerbier. Before refrigeration, both were brewed in the winter, but the Sommerbier was stronger and lagered for longer because it needed to last through the summer. Sommerbier was also called Lagerbier and Winterbier called Schenkbier.

This is a particularly useful set of analyses because it has the Winterbier and Sommerbier from the same brewery for the same brewing season. Which means we can make meaningful comparisons between Winterber and Sommerbier.

A couple of general observations to begin. I'm shocked at the high lactic acid content of every sample. I'd have expected it to be no higher than 0.1%. Over 0.2% I would have expected to give the beer a detectable tartness. The gravity of most beers is surprisingly high. The strongest Sommerbiers look more like Bocks, with gravities over 1060º and ABVs over 6%. The modern equivalents of these beers - Helles or Dunkles Lagerbier have much lower gravities, usually around 12º Plato or 1048. On its website, Tucher amusingly claims that the recipe for Original Urbräu has been the same for 150 years. Clearly that's bollocks

There are a couple of examples where clearly the same beer has been analysed as both a Sommerbier and a Winterbier: Tucher, Lederer and Lechner.

As you'd expect, the Sommerbiers have a higher average gravity: 1058 compared to 1053.6. So a difference of 4.4 points. But there was considerable variation across different breweries. Ranging from a negative 0.3 points at Mailänder to a massive 11.7 points at Dürst junior. Interestingly the average FGs are almost identical at 1016-ish. The inevitable consequence of which is that the degree of attenuation of Winterbiers is lower. Modern Lagerbiers are very different, averaging well over 80% apparent attenuation.

The Sommerbiers range from 1048.8 to 1064.7 and the Winterbiers from 1047.6 to 1059.6. Which means that the weaker Sommerbiers have a lower OG than many Winterbiers. It's a lot more variation than you would see in British beers of the same type from the same region. Though 14 of the 28 samples of Sommerbier had a gravity within two points of the average. For Winterbier, that was 13 of 23.

Unfortunately there's nothing about hopping rates. So I can't confirm that Sommerbier was more heavily hopped than Winterbier.

I'm sure I'll be worrying you with plenty more from "Chemie der menschlichen Nahrungs- und Genussmittel". It's so full of information.
