I'm all over the place. My favorites include:
Schlafly TIPA - Probably the best and most acclaimed beer to come out of St. Louis in a while. http://draftmag.com/beereditor/your-next-favorite-ipa-schlafly-tipa/
Ommegang Hennepin - A great Saison if you're into Belgians.
Beamish Irish Stout - I had it in Dublin 2 years ago and it's head and shoulders above Guinness. Unfortunately, it's not available in the US anymore.
Anchor Steam Beer - The California Common that started the whole craft beer revolution in the US.
Stone Smoked Porter - My wife's favorite beer, so we usually have plenty on hand. My favorite smoked beer.
König Ludwig Weiss - My favorite beer out of all the beers that I tried in Germany.
Fullers ESB - Had it on tap at their brewery outside of London and it has been in my regular rotation ever since. Best representation of the style.
Pizza Port Hop Ramen - A West Coast IPA with ramen noodles added to the mash. I tried this at their Carlsbad location for the only reason that it sounded weird. It was my favorite beer of the trip. I hope to clone this beer this summer.
Worthington's Red Shield - I probably drink more of their White Shield which is an IPA, but this pale ale really allows you to taste and appreciate the complexity of Burton upon Trent water.
Monteith's Original - A nice malty English pale ale from New Zealand.
I also have a beer that I just brewed that turned out really well. It's a single malt single hop session IPA. IBU's are in the 40's but it's only 3.9% abv. It's dry hopped so it has a great cascade hop aroma and bitterness. I've almost killed a 5 gallon keg of it over the past week and a half. I brewed it the day after the Miller trade so I coined it Miller 39 IPA.
