I found out that I am getting some gift certificates to midwest for Christmas....so I would like to purchase a Blichmann conical. I have been investigating/researching for a while, but would like some more recent feedback/advice. Would you recommend buying the 7 gallon conical or the 14.5 gallon conical (for just $40 more)? I am leaning towards purchasing the 14.5 gallon conical for the value.
I mostly brew 5-gallon batches, but I do have a 15-gallon brew kettle and have brewed a few 10-gallon batches in the past. Is the empty headspace a concern for a 5-gallon batch in a 14.5 gallon conical? Should I just purge the conical (similar to a keg) with CO2 before racking my wort? Thanks for your help.
