Pitching Second Yeast

[mxyzptlk]

I am getting ready to pitch a higher-alcohol yeast to the secondary for my barleywine. Should I use a 6-1/2 gallon carboy for a 5 gallon batch? I know when I used a champagne yeast in the secondary on another batch it foamed up quite a bit and I was concerned with an overflow. I am thinking pitching to a 5 gallon carboy might be a mistake for a secondary here?

yeah use the bigger carboy. if your beer is in danger of krausening at all in the secondary you want something bigger than 5 gallons or you'll wind up with a mess.

I put cherry purre in a 5 gal secondary and it went through a second fermentation that I did not exactly expect (pretty active). I wished I would have used the larger carboy... drengel's advice is what I would recommend as well.
