Notes

Mash at 155 for 60 minutes
Prep Oak Cubes
Boil 90 minutes
9 grams Amarillo @ 45 minutes

2 packets of Safale US-05 and ferment at 68 degrees until completion.

Rack over to Fermonster on top of oak cubes (see below). Pitch GB150 and just let it go. Ferment at 72 degrees.

Weigh out 0.30 oz. (8.72 g) of dry oak cubes. Boil for 10 minutes and dump water. Boil another 15 minutes and dump water. Add Knob Creek bourbon to oak cubes in a sanitized glass container on brew day and store in a dark place until adding.

Cold crash for 3 days before packaging.

Keg and carbonate to 2.2 volumes of CO2

UPDATE
A truly amazing beer. Will be re-brewing for sure with one minor change (more oak - up to 0.4 oz.). Hints of dark fruit with notes of cherry and slight oak. After 4 months in the fermenter beer finished at 1.001 for a 9% beer, that has ZERO hints of alcohol. Carbonated to 2.8 volumes in Belgian bottles.
