Whitbread brewing records held at the London Metropolitan Archives |
As you can see, the gravities are very similar, starting in the low 1030's before the war and dropping to 1028 after 1942. Whitbread's Mild was tiny bit more heavily hopped, but scarcely enough to be significant.
The grists are quite different. Lees was much simpler: just pale malt, a touch of black malt, glucose and invert sugar. Until flaked barley and flaked oats appear in the later war years. Whitberad used more different types of malt, in particular crystal and MA malt. But the biggest differnce is the colour. Whitbread Mild was around 90 EBC, Lees just 29. So despite being broadly similar in terms of strength, thse two beers must have tasted and looked pretty different.
Lees Mild looks a fair bit more thin and watery with that crazy low final gravity too, compared to Whitbread's.
ReplyDeleteThe Lees 1939 mild was a good bit more attenuated 1.005 v's Whitbread Mild 1.010. An if this trend continued through the decade it would would have been a much dry beer than the Whitbread Milds
ReplyDeleteNote the decline in hopping rates starting in late 1941. It's more pronounced for Whitbread, but both recipes were altered.
ReplyDeleteDid this reflect wartimes shortages, resulting in beers with lower levels of hop bittering, or was it due to introduction of new hop varieties with higher levels of alpha acids?
Thomas, the reduction in hopping is probably due to shortages. Britain was importing a considerable percentage of the hops used in brewing. If you look at logs from the 1930's you'll see American hops, Saaz, Hallertau, Poperings. Obviously, there was no access to continental hops after 1940.
ReplyDeleteThe gravity was falling, too. So you would expect some reduction in hopping rate. The one to look at to remove the influence of the beer's gravity is the hopping rate per quarter of malt. Which, for Whitbread, fell from 8 lbs per quarter to around 6. For Lees, it was dropped from around 7 pounds to a shade under 6.
Ron I've long wanted to make the recipe, but I'm in the States and our ability to obtain either Brupaks or Brewferm is nil (I've made my own, but I've found it extremely difficult to get it dark enough without just making a black ash tea). I'm thinking of making an approximation of it, but using Baird's chocolate, I'm predicting 51 EBC and Fawcett pale chocolate (what I can get locally) even lower of course, at 39 EBC. Nowhere near your 100 EBC. I know colorant ideally won't much of anything but color, but am wondering if this much a gap between what I have and your recipe's 100 EBC, would you expect a significant flavor difference?
ReplyDeleteAside from the color (never seen a mild that dark, which all the more made me want to achieve it), the IBUs surprised me - just comparing the Lee's at 1.035 OG and 27 IBU and a BU:GU of .77, with Graham Wheeler's Highgate (BU:GU .577) or Bateman's (.71), I find the Lee's hopping interesting. Is this a bit of an outlier for postwar milds?
