I've noticed that some of the HF beers have numbers; e.g., Civil Disobedience #5, #6, and #7; Madness & Civilizatoin #1 and #2; Society & Solitude #1–#6 etc. Are these each unique beers or just different batches of the same beers?
They're all unique beers. Hill Farmstead has been re-brewing the Society and Solitude IPA series recently. Civil Disobedience are blended barrel aged saisons (the new one is blended with Belgian lambics) and Madness and Civilization is for barrel aged stouts.
