Fullers AK 1887 - 1920

Following on with my Light Bitter theme, I thought I'd take a closer look at Fullers AK.

Or, to be more accurate, its decline and fall.

Fullers AK started off with a classic gravity for the type or 1050º. Well, at the top end of a typical gravity.  This was chipped away a little in the years 1887 to 1914, but it was still a respecatable 1045º when WW I kicked off. What would count as a respectable Best Bitter nowadays. But at the time, the weakest of Fuller's Pale Ales.

The first couple of years of the war didn't have a huge amount of impact. The OG dropped less than one point bewteen 1914 and 1916. The years after that were far more cruel. By 1918, AK's gravity wasn't much more than half of what it had been at the start of hostilities.

Things pickled up again in 1919, but still left AK only a few decimal points above 1030º. Just two-thirds of its pre-war gravity. However, the hopping rate did increase during the war. Presumably to try and compensate for the fall in gravity.

Next we'll see what happened to AK between the wars.

Hi, you've probably mentioned this somewhere before but what's the difference between lbs/qtr and lbs/barrel?

Ron Pattinson said...

Che Soffe,

lbs/barrel is the quantity of hops per 36 imperial gallons of beer. lbs/qtr is the quantity of hops per quarter of malt (336 lbs of grain).

Interesting to see that the lowest OG (April. 15 1919) has one of the highest attenuations. Lots of sugar I'm guessing?

oldAbobscoo,

at 15%, almost exactly average. That reminds me: I haven't published the grists.
