I think "kesor" is wrong. Shouldn't it be "kesy"?
Yes, you are right. This sentence is now being altered. It's still correct, so I'll leave it and change the definition, but it's a pretty poor quality sentence, so I'm going to consider deleting it altogether.
No, I think it's all right. When you are shopping and see a bottle of wine you already had and liked the taste.
I agree! As it is, the translation is weird: "It is this tasty wine!"
