I usually have Ed Worts Haus Pale on tap, but with Hallertau (or Saphir) instead of Cascade. Always comes out great, quick turn around time, middle of the road gravity, and most beer drinkers enjoy it.
This one is a regular batch as it stays on tap as it is a huge hit with everyone who is not used to home brewed beer(The Budweiser crowd) and is a SOLID easy weekend drinker that even seasoned my seasoned home brewing friends love. Credit to The Electric Brewery for this one as I re-sized it and lowered the IBU's a touch in BeerSmith for a 5 gallon all-grain batch. There is also a lager option for this recipe in the link.
Simple and delicious.
I call mine the "Blond Beachcomber"
9lbs 8oz 2-row Pilsner(2.0SRM)
1.25oz Hallertauer(4.80 Alpha) @60min boil
1 Whirlfloc Tab
1 pk S05 or WPL001 Yeast
Sach rest at 152 for 60
Mash out @170 for 15-20mins(Batch Sparge)
Ferment at 62 Deg for 3 weeks
Keg at 10PSI for 2 weeks
My other "always on tap" is the all-grain Chinook IPA from Northern Brewer.
During the holiday season(Fall-New Years) I usually drop in a keg of Pumpkin and a keg of Holiday Ale. The all-grain Holiday Ale kit from Midwest supplies is awesome.
