Tennent's Lager 1889 - 1890

Many thanks to Barm for sending me a couple of pictures from some early Tennent's Lager documents. They're what I've based this post on.

They aren't brewing records, but an overview of the quantity of Lager brewed and the materials used. They still contain plenty of useful information such as OG, hopping rate and grist. Plus they give an idea of how much Lager Tennent were brewing.

The records cover 1889-1890 and in the 6 months that they cover, Tennent brewed 2,418 barrels of Lager. Assuming that they brewed a similar amount every month of the year, that comes to an annual output of 4,836 barrels. Or bugger all. Large London brewers had single batches of Mild Ale of more than 1,000 barrels. Though this is before Tennent's shiny new Lager brewery first brewed in 1891. Presumably they upped production a bit then.

Let's move on to the beer itself. Its gravity was around 1056º, about dead on average for the period. And a couple of points below a contemporary London X Ale. It's odd they way they changed the grist a few times: occasionally brewing it all malt, but mostly with about 25% maize. Though there were single brews that used either rice or sugar.

The hopping rate is very low, way lower than even for Mild. Here's a table to show how it compares with London beers of the same period:

In multiple 19th-century sources I'd read how much more lightly hopped Lager was than British beers. This confirms that. Tennent's Lager had about half as many hops per barrel as even running beer.

looks like they took an American approach to lager brewing that a continental ie using flaked maize?

Ron Pattinson said...

Oblivious, I know - the Germans (other than Bavarians) would have used rice rather than maize.

Jeff Renner said...

I've done some research on late 19th century American lagers. Rice was the preferred adjunct grain for premium beers until dry milling of maize was perfected around 100 years ago, and the oily (and potentially rancid) germ could be removed. Then maize gained far more acceptance since it was cheaper.

Normally in the US, grits were used rather than flakes. They were cheaper but required separate cooking.

After I wrote an article about American lagers of this time, which I called Classic American Pilsner, in Brewing Techniques in 1995, this style has gained popularity among homebrewers around the world.
