So I am a beginner in brewing so sorry if some of these are basic questions. And I’ve been looking into aging my cider in an old whiskey or bourbon barrel and I have a few questions. First is if I put 30 gallons of fermented cider into 50 gallon barrel, would that extra space do anything to ruin the cider? Because I only want to do about a 30 gallon batch or so and I can only find 50 gallon barrels. The second question I have is, does anyone have a preference on if they use bourbon or whiskey barrels? And then the third is does anyone know where to find cheap used barrels?
