I got a cask for Xmas, which I have said in a previous post. Well, now I have cracked it open the first week to see the change in color, and it is dramatic. It's gone from clear to a more scotch-like (J&B in particular) amber. That's a pretty drastic color change for a week. Here are some photos to compare it from the first draw and the initial 2 liters that I put in.
