I have always stuck with the local places here for homebrewing. Lucky for me AHS is one of them
Tried quite a few of their kits that are clones of comerical beers and they were rather close. AHS does tend to over hop their kits a tad IMHO. Which for me is not a bad thing as I am a hop head, but it does tend to make their versions a little hoppier then the comercial ones. Other then that, never had an issue with them.
