I have a choice of B-day present this year and im thinking of oak barrel (10-15gal), i would like to know you opinion if its worth it (price maintenance ect). I want to use it to make sour beers, not regular oaking (i do that in carboys with cubes/spirals and im happy with results). Do you think i should just try making sours in regular carboys instead (i have bunch of those and im fine with keeping 2-4 occupied for a year or so)
