My 18 month tripel is so great right now, but I only have 6 left. I hoard them with passion. My 12 month old Tripel is really just starting to come around. It's 1-2% stronger, so I am still planning on waiting another few months before I start consuming many of them, I have about 40 of them left.
BTW, the belgian rock candy is cool looking sucrose. Once it dissolves its just table sugar. The candi syrup is a little different, and the amber and darker grades can make seriously good Dubbels and Dark Strongs. You can do a similar, but not quite the same, version of this by making carmelized invert sugar on your stove.
