I've long been a fan of NewCastle. When I was a poor college student it was an occasional treat. Over the years I have come back to and gone away from NewCastle.
Very smooth beer - goes down with ease.
I like mine served fairly well chilled.
The one problem I have with NewCastle is that unfortunately I have run across my fair share of "Skunky" tasting bottles. Its been suggested that it could be because of the clear bottle.
Make sure you buy your NewCastle from a store that regularly replenishes its supply to avoid the skunky taste.
