I prefer stouts, porters and dark ales and I'll switch to an amber occasionally. I stay away from domestic mass-produced beer. There are plenty of craft breweries around so there is a pretty good selection of all kinds of beer available.
That said, my favourite beers are the ones I make at home. I've been a home brewer for several years and one of the local craft breweries also makes DIY home brew kits which are easy to use and taste awesome.
