Witcher 3 - Storeroom of Kaer Trolde
This is not just a good cask, it's a great cask.
Witcher 3 in general has excellent casks, but this one was exemplary: the wood looks nice, the hoops are in the right place, and the head hoop has been removed so that the staves can separate enough to remove the head, which is just fantastic attention to detail. The two other casks show there isn't just one cask asset, too, which is very nice to see. (in fact, there are at least four, but they'll be seen later, when I want to cheer myself up).
Random cask trivia: the wooden corks you see in the other two barrels are called bungs, and can be found on the head (as we see here) or in the side of a cask. And, as might be though, the hole they plug is, indeed, called a bunghole. My inner seven-year-old is cackling.
