Just having a glass of one of these now. After having smashed my usual glass thermometer, I stuffed up the mash by using an uncalibrated temporary digital replacement [(that I later found to be 2c higher than actual) - assuming my new lab spirit thermometers are accurate anyway.]
Considering I managed a single infusion at 68c and a resultant FG of 1.014, it's still a well balanced beer. It's a bit chewy and feels too sweet for style, but the characteristics and complexity of a JSGA are there and you can tell it would be a winner if it were dryer. I've got the grain in stock to make another one and am really looking forward to it!
A question for the DR: If I split my alpha and beta amalyse rests, what rest periods and temperatures would you recommend to get a similar (but slightly higher attenuating) result to a 66c infusion?
PS: Good to see you putting your home grown Victoria to a noble use.
Cheers
