Ok.. I keep reading these recipes for one gallon of wine,to make it a short question. can I make 1 gallon of wine in a 5 gallon ail pail or will it be too much head space? If not where can I get smaller pails/ for a gallon of wine I would need about a 2 1/2 gallon pail correct? please help,it's starting to drive me nuts looking for the answer... thank you
