43% ABV ! No wonder I fell off my bar stool. Now where did I put that decimal point . . .
In fact the OG was 43, the racking gravity 10.5, so using the approximation ABV% = OG – PG (present gravity) divided by 7.46, its strength at racking was 4.4% ABV. At the end of the Firkin the PG had dropped to 6, so strength was up to 5% ABV.
In contrast the Firkin of Jail Ale (that was surplus to requirements for a local pub at lockdown), had under 1psi in it on spiling, its PG remained at 12 for the 30 days it took me to drink it, and I had to add CO2 from an S30 cylinder all the time, which was a bit of a disappointment. It tasted fine nevertheless. My excuse for switching to commercial beer was the uncertainty of getting supplies, but I’m pleased to say that’s now sorted – apart from having to use dried yeast for the first time in 36 years.
