I bought two cases of bottles and 1 case (6) of magnums in about '90. I'll have to check, but around £50/bottle, slightly more than pro-rata for the magnums, from memory.
Got some winos coming round for dinner tonight. The (expected) highlight will be a Sassicaia mini-vertical, '85, '96 & '01. Doing venison haunch with it. Can't wait.
