I was toying around with the pitching rate calculator in BrewMath and I have a couple questions. According to the calculator I would need 3 vials of White Labs yeast for a 1.050 SG 5 Gallon gallon batch. This is according to the directions saying that the SG should be 1.050 and the FG should be 1.010. Does this sounds right? If so, why are the kits only shipped with 1 vial?
