I wanted to bulk age a batch that I had going as well. It was a three gallon
batch and was worried about the excess head space. I bottled it last night instead and will cellar it in the bottles till Christmas time.
Sure tasted good last night for something so young.
Have a 4 gallon batch going as well , for this one I'm going to try and find a 3-4 gallon plastic carboy and then bulk age in that.
