I ask because I have a 3L H3 Cab Sauv from 2010 sitting in my cellar and I keep thinking we need to find an occasion to pop open a giant bottle like that but have not. Your tasting notes made it sound like it was perhaps over the hill and I got a bit panicky. My cellar is 55F for about 6 months of the year but creeps up or down to/from 65 max during the Summer so I was wondering if yours was stored at a warmer temp or similar temp as mine. Sounds like I need to throw a Summer BBQ in a few months!
EDIT: oops, that sounded defensive. I actually really want to know!
