I've been holding on to several vintages over the last few years with the intention of drinking these vertically with a couple buddies. I know it's not super impressive, but I currently have 10,11,12,13 SN Bigfoot vintages. I'm hoping to wait until next years batch, so I we can taste 5 years of Bigfoot! I know this stuff ages superbly. Which multiple vintages of Bigfoot has anyone put together to drink?
