First off, if you don't know what Oktoberfest is, here's Wiki.
http://en.wikipedia.org/wiki/Oktoberfest
During all Oktoberfest seasons, I've drank beer, but never "Oktoberfest" beers. This year, I'm going to be looking for various seasonal Oktoberfest beers and doing a quick taste test.
Of my usual breweries, I didn't see any of their Octoberfest beers out yet, so I will keep checking back every couple days, so this will be a progressive post, expanding as I can get more brews in.
Anyhow, first up with the Sam Adam's Octoberfest (with a C, not a K)
Price = $8 for a 6 pack of 12oz bottles.
It tastes good for a cheap (non-craft) beer. Has a little bitterness, just enough to not be a sweet beer; Definately a good hops and malt blend. The after taste reminds me a bit of coffee. Yeah coffee, not toffe.
Overall it's very drinkable in high amounts and would work well with Sausage and sauekraut, which is what Oktoberfest is all about.
Score = 80%
My scoring system may be a bit different than yours because, after all, this is totally subjective. But to give you guys another frame of reference, I would put Miller Light, Bud Light, Mich Ultra, and Coors light all in the 50-59% range. Mephistopheles by Avery get's an A+ at 98%, but it also costs me $8/12oz bottle.
I plan on checking out the Oktoberfest beers by Avery, Boulevard, Left Hand, Carolina, Goose Island, and the brewery here in Topeka, Blind Tiger. If you have any other suggestions, I'll see if I can get them here.
