I'm a newbie and just now started my wine making endeavors. A guy I work with told me to only use glass carboys for fermentation. I bought 7 one gallon glass carboys for cheap and plan on making small batches of different recipes. Will it be alright to do the initial fermentation in a one gallon then transfer to another one gallon? Also what is a good bucket to use thats cheap? If I use the one gallon glass for initial fermentation do I need to put an airlock on it to start with or just put something over it? Thanks!
