Talking with my wife during our last racking adventure, we pretty much decided to buy nothing but 3 gallon Better Bottles for our needs. Most everything we make will be in either 3 or 6 gallon recipes. We love the ease of cleaning, light weight, and compactness of them. occasionally we will make a 1 or 5 gallon batch, and will use glass. 6 gallon glass is so heavy, and I would hate to have a mishap and loose 6 gallons of wine. Just our idea.
