Fermentation Notes
Fermentation took a bit longer to start than I expected, however, it was pitched into wort at about 64 degrees F, not the greater than 70 the package recommended.


Tasting Notes
Was happy with first tastes. A bit flat, but tastes good. Remember to let keg suck out grains before drinking :-). A slight extract-like "twang" to it. Will try and see how it tastes again soon :-)6/1/03 -- Keg is almost empty. This keg started to taste really bitter due to hops. However the taste mellowed out, and it became a really good beer. Not great, but very drinkable...


Problem Notes
Brought lots of trub from fermentor into keg when kegging.
