I am dusting off the Grainfather and plan to run a 2-Hearted clone this weekend. It's been a while so I need to refresh on the process and recipe mods needed to run in the GF. Hmmm...clearly I need to brew more often!!
Falconers Flight Extra IPA is a Brewers Best kit I tried last year some time. I've been hooked since and brew a batch every couple months. Millenium for bittering and all Falconers Flight after that. It's good stuff.
Chill it. Taste it. Let us know.
27 sounds high. I jack to 20-25 and shake for a few days if trying to force carb fast. After that, I dial down to 7-12 depending on the brew. It seems like more than a week at 20 results in too much carb. I also carb cold starting right after racking to the keg.
