Year old brown ale

I had the last bottle of my Nottingham nut brown batch last night. I couldn’t believe how good it still was. It was awsome!
Took a look at my notes and realized I brewed this batch 5/21/11, bottled it 6/5/11. Before I checked I could have sworn I brewed it only 6 or 7 months ago.
