Black Ale - something cheap to fill up a carboy

I threw this recipe together for something cheap to fill up a carboy that's going to be empty, I just have 1/2 an oz of willamette left. I have 1/2 an oz of columbus too should I use that for the bittering addition and bump the willamette up for flavor/aroma additions? The yeast is comming from a bottle of another beer. All I have to buy is the grain, trying to make something for less than $15 :fro:


6.00 lb Pale Malt (2 Row) US (2.0 SRM) Grain 72.7 %
0.75 lb Munich Malt (9.0 SRM) Grain 9.1 %
0.50 lb Black (Patent) Malt (500.0 SRM) Grain 6.1 %
0.50 lb Caramel/Crystal Malt - 30L (30.0 SRM) Grain 6.1 %
0.50 lb Caramel/Crystal Malt -120L (120.0 SRM) Grain 6.1 %

0.50 oz Williamette [7.00%] (60 min) Hops 17.4 IBU

1 Pkgs American Ale Blend

Looks like a tasty Porter.

If this was me, I'd probably add 1/4 to 1/2 a pound of chocolate malt.
