Two different markets. Unless Absolut has registered its trademark in every conceivable trademark category, I'd say thay haven't got a leg to stand on.
To my mind, it's just a bit of cheap publicity. Sabre rattling to say"we're bigger and more well known that you."
A company I used to work for tried similar. They had the trademark for textiles, the other company for electronics. No case to answer was the verdict.
