Let's Brew - 1886 Barclay Perkins XX Ale

Just like last Saturday, I'm providing some relief from the constant barrage of Heineken and WW II stuff. With a recipe from my barely-started book, "Free!".

19th-century Mild Ales can confuse the hell out of people. Especially stronger ones, like this. Pale, hoppy and pretty strong. What exactly makes it a Mild Ale, then? The simple fact that it was sold without any ageing, just a couple of weeks, at most, after being brewed.

XX was considerably more heavily hopped than X Ale: 12 lbs per quarter (336 lbs) of malt, compared to 8 lbs. In fact, the hopping rate was the same as for PA and XLK, Barclay’s two Bitters.

The malt bill couldn’t be simpler, just a single type of pale malt. There’s really nothing at all to discuss there.

Equal quantities of East Kent and Worcester hops, both from the 1885 harvest, made up the hops. As this beer was brewed in May, the freshest hops you could get.

Sadly, Barclays didn’t brew this beer for much longer. Like most other large London brewers, by around 1900 they’d slimmed down to brewing just a single Mild Ale. This batch was brewed on their small kit and consisted of a mere 50 barrels. While X Ale was often brewed 1,000 barrels at a time.

Heineken's first Lager

Yes. Yet more Heineken shit. Going a bit further back this time. Back to when they were just starting to switch from top to bottom fermentation.

It's unusual to have a review of the first appearance of a beer. Especially one that's become as big as Heineken. Though it isn't quite what tou might assume.

"Mr Gerard A. Heineken, the owner of the Hooiberg, one of the oldest breweries in our city, is one of those industrialists, to whose entrepreneurial spirit and energy the young Amsterdam owes great thanks. He develops a useful branch of industry in Amsterdam, which was rightly proud of its brewers in earlier times, and by honoring the taste of the day and brewing Bavarian beer, he has given the Dutch the opportunity to purchase an excellent folk drink, brewed on their own soil. Last night, at his request, a few hundred residents of the town came to taste the new brew, which was excellent. It is proverbially difficult to judge the taste of others, but if the public wants to know the subjective opinion of a hundred Amsterdammers regarding this new Bavarian beer, then we can say that it is a spicy, clear, very tasty drink, which seemed to us to combine the good qualities of Viennese beer with those of Bavarian beer. "May this beer soon become generally known, and refresh thousands!" Wished one of the guests at the Vyfhoek. We share this wish, and hope that Heineken's Bavarian will soon be as well known in the Netherlands, as Guinness's Porter in Ireland, as Bass's Ale in England."
Algemeen Handelsblad 24-02-1870.

Sadly, Heineken is now better known in England that Bass Ale.

Why not what you might have assumed? Because this wasn't a Pilsner, but a beer called Beiersch. Which means Bavarian in Dutch. That is, a dark Lager in the Munich style. In the early days of Lager expansion, it wasn't Pilsner, but Vienna and Munich Lagers which were all the rage. Hence the reference to those two types of beer in the article.

At one point, Heineken brewed both a Munich and a Vienna Lager. Sadly, I've no details for the latter, as it was dropped before the earliest brewing records I've seen. All I've seen are labels.

Something other than Heineken

Only kidding. Of course it's more Heineken stuff. Lots of crumbs of knowledge for me to peck away at.

Lagering times is today's topic. Did I mention before that there wasn't much about them in the records? That's not totally true. There are a few details and dates. Annoyingly, no temperatures are given. My guess us that the lagering tanks would have been filled with the wort at the temperature where fermentation ended. That is 5º-6º C. Then slowly cooled to around freezing.

The pattern is fill the tank, leave it open for a few days, seal it up and finally let the pressure increase. That pressure coming from the continued fermentation while lagering. Fermentation must have occurred as the eventual FG is a good bit lower than at the end of primary fermentation. All, with the exception of Export Pils, lost more than 2º Plato during secondary fermentation.

Is lagering really a secondary fermentation? I suspect not, technically. As it's really a continuation of primary. Who gives a toss about that, really? I've certainly more worthwhile quibbles to waste my time on.

Yet another table showing that fall in gravity I mentioned a short while ago.

The lagering times are pretty reasonable. Around 10 weeks for the Piseners and for Münchener more than 17 weeks. Just a shame that there are no examples of the two Lagerbiers. I'd love to know how long they were lagereed.

That's enough fun for today. I've some more numbers that need fiddling with. Though,  as it's not raining, I may nip out for a quick walk and read of Private Eye. That night happen to take me past Ton Overmars. Where I may as well check if they've refilled the shelf with Abt.

Let's Brew Wednesday - 1935 Heineken Pils

I was so happy when Peter Symons pointed me at Heineken’s pilot brewery records. Because they contain all the process details missing from the main brewery records. All the really good stuff: decoction, hop additions, fermentation profile and lagering times. Making this one of my most accurate recipes.

The grist is pretty simple, consisting of just pilsner malt and rice. Not a great deal you can say about that. I assume that the rice was at least partially included to keep the body and colour light. The rice was mashed in separately, but there wasn’t a cereal mash. As you’ll see in the mashing scheme below.

A single type of hops was used, Leitmeritz from the 1934 season. Leitmeritz is the German name for the Czech town of Litoměřice. The hops grown there were similar to Saaz, which is what I’ve specified in the recipe.

Pitched at 45º F, the temperature rose to a maximum of 50º F, before falling back gradually to 43º F.  Primary fermentation lasted a total of 9 days. Lagering lasted just over two months – a total of 72 days.

Still more ridiculous Heineken detail

Well, that was a busy weekend. Pub on Saturday, roast dinner preparation on Sunday, as well as the IPA talk. Time for me to relax a little. Ant what better way  to relax than looking at Heineken's brewing processes in ridiculous detail. It's now the turn of primary fermentation

What strikes me is how generally similar it us to a UK top-fermentation. The temperature slowly rises in the first half of the, peaks, and then falls back to slightly below pitching temperature at the end. The only real difference is that the temperatures are all a good deal colder. And that the fermentation takes a few days longer. In the UK 5 or 6 days was typical, while all Heineken's beers took around 9.

It's a shame that there's no record of what happened in the lagering tanks. There must have been a fermentation because the finishing gravities were: Beiersch 4º Plato, Pils 3.4º Plato and Bok 5.6º Plato. The Pils seems to have been lagered about 2 months. I'm not so sure about the length for the other beers, though it does look as it was longer for Beiersch, possibly more than 4 months. 

Annoyingly, lagering is the one part of the process which isn't properly documented. I assume that the beer was slowly cooled to around zero. The tanks were bunged at a certain point implying that it was allowed to condition naturally.

I was going to head out for a walk but it's absolutely pissing it down. The tropical-style rain we've started getting quite frequently. Just as well Amsterdam never floods.

Even more Heineken tedium

It's another busy day. Sunday dinner won't cook itself. I'll quickly bash this off while the oven is warming up. 

Today we're looking at Heineken's boiling schemes. Of all the essential processes involved in brewing, hop additions are some of the post poorly recorded. Other than a few Barclay Perkins records from between the wars, I've almost no information. Which is why I was dead happy to find Heineken's pilot brewery records had full hopping details.

Oddly enough, the standard records which have almost nothing about process do note the hop charges. Just not the timings.

What's unusual is that a very high proportion of the hops were added late in the boil, a mere 20 minutes before the end. And very few hops were added early in the boil. Presumably creating beers with a fair amount of hop aroma but little in the way of bitterness.

Got to leave you now. Time for the beef to go into the oven.

More dull stuff avout Heineken in the 1930s

I keep finding reasons to delay finishing "Blitzkrieg!". It is complete. All but the small section on brewing in the Netherlands during the war are done. But I keep finding more information. And requesting the archive digitises more Heineken records.

You can request five documents per month. I used up my monthly ration this week. All on records of the pilot brewery. One in particular I'm keen to take a look in: 1944-46. I've currently no information later than 1943. I'm dead excited. Though patience is requires. Three to six weeks the process takes.

A couple of days later, I learnt Peter Symons had requested some of the same documents. He's been pointing me at various documents from the Heineken archive that he's already had digitised. Between the two of us, we should get through the interesting ones pretty quickly. Then move on to the Amstel stuff.

I can't take too long over this.  Got to be down the pub, well, brewery, quite soon for my Saturday afternoon pints with mates. The highlight of my unemployed week.  I'm not going to bang on too long about this double decoction. I want to line my stomach with some lunch before this afternoon session. Andrew chews his way through pints disturbingly quickly. I always drink faster when I'm with him.

Heineken Pilsener was mashed very differently to their Münchener, which had one more decoction. The heating and boiling of the decoction were shorter. While the saccharification rest at 66º C was far longer. The two just about balanced each other out and the whole process was only 5 minutes shorter, despite there being one fewer decoction.

The shorter boils make sense. They'd have been wary of darkening the wort. Not sure about the reason for longer rest.

That's enough about decoction. I'm thinking about my sandwich. Dolores made meatballs. Always dead good. This batch are particularly nice.

Reminding you of the mega IPA event tomorrow. Where I'll be doing my talking thing.  Among with some other blokes.

Informative and fun, I hope.


This Sunday there's a bug IPA event with Vinnie Cilurzo, Mike Karnowski and Mitch Steele. Plus me giving a talk on the history of the style. You can find more details and register for the event here:

Let's Brew - 1886 Barclay Perkins PA

You're probably bored shitless by WW II and Heineken, so here's a complete change of pace. A Bitter from the 19th century. A recipe which will feature in my book after "Blitzkrieg!". A book which, although I haven't officially started it yet, already runs to over 16,000 words.

Barclay Perkins were very late to the Pale Ale game. While London rivals Whitbread had introduced their version in 1865, Barclays waited until the 1880s to follow suit. I’m not sure why it took them so long. Perhaps, like Courage, they took their Pale Ale from another brewery which had the right water profile for the style.

By Barclay Perkins’ standards, the batch size was tiny. Brewed on their small plant, it was of a mere 97 barrels. While X Mild Ale was bashed out 1,000 barrels at a time and even the powerful Stock Ale KKK was brewed in batches of 700 barrels. It demonstrates how much of a niche product Pale Ale was at the time.

The effect of the 1880 Free Mash Tun is clear to see in the grist, where there’s unmalted grain in the form of flaked rice. In the early days of adjuncts, this seems to have been a popular choice. Though later most brewers switched to maize. Rice does make sense for a Pale Ale, however, as lightness of both body and colour were highly desirable characteristics.

Two types of East Kent hops, one from the 1884 harvest, the other from 1885 were employed, along with Worcesters, also from 1885. The dry hops weren’t recorded for the is brew, however they were in one 15 years or so later and I’ve used that figure. Which, at 12 ozs. per barrel, was rather a lot.
