To clarify: These are the best individual beers I've everdrunk, so it is only part taste, part good memories, and part overall experience. This is NOT the best type of beers I've had. Although taste is still important to actually make the top 5.
Honorable Mentions-My keg stand record-I am definitely not the best drinker among my friends. I'm no slouch, but several of my friends can definitely drink me under the table. I do, however, hold one record that I have yet to see beat. I hold the record for longest keg stand. This is when your friends hold your legs up in the air so you are doing a hand stand on a keg (I'm not sure why this part is necessary) and you suck beer from the keg tap as long as you can. It is a pointless record, and I should take no pride in this lame college tradition, and yet I do take pride, I believe the beer that night was filled with Heineken, but it might have been Bud.
For obvious reasons, I no longer remember.
Boddington's with Rick, my brother.
Odd memory, but, I remember drinking
Keystone at my friends' Steve, Chirs, and Katies' apartment, when Ben showed me a Christmas tree decorated with Keystone cans. Should have looked white trash, and yet, it didn't
Miller Hi-Life while watching an awesome meteor shower Antioch
My first Duvel with my Dad- In Seattle with my parents, visiting from college, I poured my beer correctly (on the side of the glass, with just enough head) My dad said, "Somebody learned how to drink beer correctly"
5. The Fat Tire I had at Mucky Duck when I asked my friend Tom to be my Best Man-
Fat Tire is fantastic, but it mainly makes the list because of the memory attached. I was actually really nervous that day. I knew Tom wasn't expecting to be asked, but I knew he was the right guy for the job.
4. James Squire Porter at the James Squire Brewery in Australia-
Drinking a beer in the same place its brewed is awesome. Especially when its your favorite beer from the country you're currently in.
3. The Dusseldorf Alt with my managers at Park/Beach Chalet-

Beach and Park Chalets are San Francisco Restaurant/Breweries just south of the Cliffhouse. The Dusseldrof Alt was a beer that was dark, full of flavor, and 12 percent alcohol by volume. Oh so good. Our brewmaster, Aaron, eventually turned the "leftovers" into a scotch.
2. The Riptide Red at my San Francisco going away party at Kevin & Scott's house-
My friends Kevin and Scott are on this list twice... I guess their names are synonymous with good beer. I bought a large keg of my favorite microbrewed beer from my work, Beach Chalet. Kevin and Scott provided their apartment and nice keg tap and fridge. It was the "Adult" kegger.
1. The Barleywine made by Kevin & Scott-
My friend Kevin gave me this beer for my 27th birthday. We had to let it age for a half-year, and then, when it was ready, we went to Kevin's house to drink them. He greeted us with a broken rib (he got it playing basketball, he recently had a dislocated knee for the same reason. This may not sound abnormal, except when you know that Kevin is studying LAW, not playing basketball professionally.) He proceeded to break out more and more of this dark amazing nectar of the gods.
