Hi everyone! Newbie here looking forward to my 3rd season of making wine from grapes. All of my equipment is from my grandpa that’s been sitting in the basement. It’s all at least 50 years old. I have a crusher and a few 15 gallon glass demi-Johns. What do you use for your fermentation vessel if you have 15 gallons or more? I’d like to get something better than the glass demi-Johns. I’m always afraid of it breaking.
