With 90 beers on cask in one location, 4 hours is no where near enough time to enjoy all of the nuances. However, I believe the list below summarizes everything I had an opportunity to taste. The lists following that one are the memorable ones - both good and bad.

This was nice, spicy beer without being too strong.
Big Time Brewery Solo IPA (WABL)
A very nice, malty, smooth IPA.
Black Raven Brewing Bizarleywine
A great Barley Wine without being too *pruny* or too full of alcohol.
Dick's Brewing Double Diamond (Winter Ale)
Like candy! This made me think of Anderson Valley's Winter Solstice!
Georgetown Brewing Lisa's Chocolate Stout
Just the right amount of dark chocolate flavor to a well-balanced stout.
New Belgium Brewing Somersault
I was really surprised I liked this, but it had the right amount of apricot and a very nice hop presence.
Schooner Exact Brewing Spanish Cedar IPA
A very smooth, woody, well-rounded IPA.
Icky!
Airways Brewery Chocolate Rye Stout
I think this beer was actually off by the time I had a taste.
Big Al Brewing (Seattle) Flanders Red (Sour) ick!
I have officially discovered that I am not a fan of "sour" beers.
Epic Ales (Seattle) Smoked Brine (Oyster Stout)
If you think this sounds bad, it tastes worse!
Fremont Brewing (Seattle) Kentucky Dark Star (Imperial Oatmeal Stout) ick!
Surprisingly awful.
