Let's Brew Wednesday - 1969 Truman LL

I was so pleased to find this beer. Because it’s an example of a short-lived type of beer: a regional brewery’s own brand of Lager.

The first British Lagers were mostly brewed in specialist breweries. Either standalone enterprises like the Wrexham Lager Brewery and the Red Tower Lager Brewery. Or a specialist plant within a larger brewery – examples being Tennent in Glasgow and Barclay Perkins in London. There were only a handful of such specialist plants in the first half of the 20th century.

When Lager started to take off in the late 1950’s, just about everyone wanted to get in on the act and market their own brand of Lager. These were usually just brewed on the standard kit and weren’t even necessarily bottom fermented. As the 1960’s and 1970’s progressed, most of these regional Lagers disappeared, replaced by national or international brands. Only weird breweries like Sam Smiths have persisted.

Truman’s London Lager – which is what I assume LL stands for – was such a beer. And true to tradition, it was replaced by an international brand, Tuborg, which Truman’s brewed under licence.

Here’s a selection of the Lagers from regional breweries in the 1950’s and 1960’s:

Tennent’s Lager is the only one to still exist. M & B and Charrington, which both ended up in Bass Charrington, had their Lagers replaced by Carling Black Label and Tennent’s. Flowers, which ended up in Whitbread, had their Lager replaced by Heineken. Not sure what happened at the smaller regionals, but I’d be very surprised if any still brewed their own Lager.

Back to Truman’s Lager. It’s not a very complicated grist, just lager malt, sugar and flaked barley. Unlike all their other beers of the time, it doesn’t use English hops, but ones described as “Styrian”, which I presume means Styrian Goldings. The level of hopping is extremely low. So more of a Helles than a Pilsner.

I’m not sure about the mashing. It looks like a step mash, with strike heats of 125º F and 170º F. Not sure what that equates to in terms of initial heats. The fermentation, though cooler than for their other beers, still hit a maximum temperature of 60º F, which looks too warm for a true Lager. Though it was crashed down to 41º F just before racking.

Looks like a great example of a pseudo-Lager. Or semi-Lager. Though I’m not sure why exactly you’d want to brew one, other than for academic purposes.

60f diacetyl rest?

The grist reminds me of something someone might use as a base for a modern hoppy ale.

I wonder how close this might be to the original recipe for Hop Back Summer Lightning which was conceived by a former Grand Met brewer as an ale-lager hybrid.

Or, to put that another way, should we look at golden ales as the culmination of this trend as much as the start of a new one?

There have been a lot of home brewers doing fairly rigorous experiments with blind taste tests of lagers made faster at warmer temps compared to lagers made more slowly at traditional lager temperatures. There are a bunch at http://brulosophy.com

The general consensus is that the differences range from slight to none. They haven't exhaustively gone through every possible variable and every variation of malt and hops and yeast, of course. Still, I think it's certainly possible that Truman did enough playing around with their process back in the 1960s to decide that fermenting at 60F didn't have much significant impact for their recipe compared to a more traditional method.

Anonymous: The other thing is that British consumers might have had little exposure to other lagers and not really tell a small difference

I even brewed experimentally with lager yeasts at around 80 Fahrenheit. After I aged it for a while a bunch of experienced brewers said it tasted like English ale (in a good way). Not a lager taste at all but delicious. Lager can handle a lot higher temps than most people think. I suspect that traditionally a big part of the original reason for low temp lager ferment was to make any wild yeast or whatever that snuck into the beer inactive.
