I usually have one alcohol free month a year, it's something I just like to do.
The best alcohol free beers I have found are the Erdinger - alcohol frei. Also the Bavaria alcohol free wheat beer isn't too bad. Quite estery and banana tasting. I bought a pack of them last year and was most amused to have to get age verified by the assistant at Morrison's self service checkout! Both need to be pretty cold to be enjoyed at their best though...
A new favourite of mine is the Brewdog Nanny State, 0.5% I think. Can actually drink a couple of them no problem, good hoppy hit.
Would be intrested to find out how other folks find them...
