Making my first lager. How big should a starter be for a 5 gal batch? A lot of people seem to make starters at 1L, but calculations would say I need approx 3.2 liters so basically almost a gallon. Need to know so I can either buy a flask or 1gal carboy.
I assume I would decant the wort off if I were a gallon. That being the case, how long before I brew should I get the starter going, four days good?
