Looks to me like the 3/4 barrel sizes and smaller are cut down barrels but I could be wrong. Appears the smallest barrel that might be reused is the 60 gallon barrel though enough brewers together could make that work...
I took the meaning of the 1/2 and 1/4 barrels as being the planters, since they described the 132gal and 60gal as 'whole barrels'.
$75 for the 60gallon barrel is a good price though! I would just have no space to put it personally in my westside apt. Still, I'd be interested in splitting the cost with any other members if someone could house it.
Hah. It seems that you guys probably are right. I misinterpreted the info. Thanks for the heads up. I definitely can't house a 60gal barrel at my place. However, if someone can house it, I'm in too.
