i have just done 2- 10gal batches with 1 vial for each. i made a 2l starter and let it go for 24-36hrs, decanted, and made another 2l starter. poured half in one carboy and half in the other. both started to ferment after 12hrs.
I used the brewers friend site because it breaks it down a little more to help a beginner like myself. very simple to follow.
