I brewed 10 gallons of my Tripel recipe recently that got split into 2 five gallon carboys. Both are fermenting with Wyeast 3522 Belgian Ardennes. ABV will be around 9.8 when done with secondary. I bottle using corn sugar and adding more yeast (Nottingham Dry Yeast). Results come out perfect. But this time I want to finish 1 carboy with Brett B. Need opinions on if I should add the Brett into the carboy during secondary or if I should use the Brett instead of the Nottingham at bottling time.
