General Notes:

Did not hit target efficiency.
Tasting Notes:

Tasting notes taken 4/11/2010.

Poured from growler into a pint glass. Filled growler from keg and chilled for about two hours before serving.

Appearance: slightly hazy golden straw color. Head is minimal, though there is apparent effervescence. This style really should be crystal clear so, while it doesn't look bad, it really could be a lot clearer. (3)

Smell: aroma isn't bad but is very, very mild. Sweet malt is present and a very little hops aroma but, at least, there are no off-aromas. This is a light style, so I won't downgrade it too much for subtlety. (3.5)

Taste: very basic malt flavor with a nice level of flavor hops, though I think I went too far on the bittering. A little better mash efficiency would have given me a lot more in the way of flavor; though this isn't bad, it's darn mild. (3.5)

Mouthfeel: medium-light body with lightish carbonation. I think I lose a heck of a lot of carbonation when I growlerize these brews. (3)

Drinkability: low ABV and a flavor which is relatively nice and definitely light give this a pretty high drinkability. I think I will have some outside now on this nice, sunny day. (4)

Overall score 3.4 (B-). Not too bad for a first attempt at anything even approaching a lager. This one may improve over time, although its lagering temperature is just my garage temp, about 50° most of the time this season.
