I will double and triple +1 on the Ithaca, SouTier, Ommegang (and RoosterFish HopWarrior the rest is meh).
I live near Ithaca. I have always meant to but have not yet made it to the brewery. I hear it is great cause they give you free beer (tastings).
Love their Cascazilla.
Love Ommegangs Abbey Ale.
Love Southern Tier's Creme Brulee Stout and Unearthly Oak Aged IPA.
