I have just done a flight of PVW 12 lot B, PVW 15, and PVW 20 and wondered if you all have done the same. I must say this is the first time I tried the lot B and thought it was the best overall. I rated the 20yr as second and the 15yr as third. This has been a wonderful tasting experience. Has anyone done the flight of 10 yr through 23 yr? I have all five but I will have to go dry for a few days to do this.
