Coffee flavoured beer... Hmmm... i'm not really a beer drinker and this combination doesn't sound like i would try it, but... Have you ever heard of beer brewed with green tea... There's this dutch guy who invented this... He worked together with a guy who brewed beer for a hobby... Together they found the right recipy and a Belgian Brewer who was willing to produce it... And so... IKI beer was born... I tried it a few times now and i can honestly say it's the only beer i like... See also www.ikibeer.com
Just my 2 cents...
