Finally having the John E Fitzgerald 20 year. $300 retail for a 375 ml. At the bar it is $100 per ounce. It is stellar by the way, but I'm too cheap to have it on my own nickel.At those prices, I would be too.
I paid $35 for a pour of Laphroig 30-year once, but that's about my upper limit. Worth every penny and then some, by the way.
