I based the recipe on some information I found in a thread at tastybrew: http://www.tastybrew.com/forum/thread/140322
The taste is great - crisp, clean, light to moderate malt, nicely balanced bitterness and just a hint of unidentifiable hop flavor, but almost zero aftertaste. It has a nice fluffy head in the glass. You could drink a TON of this. I didn't use pilsner (because I didn't have any on hand) but I think next time I might do this with Vienna in place of the 2-row for more maltiness.
If sticking with an infusion mash, I'd go a degree or two higher. I don't think I would add any caramel malts, though - I like the crispness. A single or double decoction would probably make this outstanding.
Also, I didn't actually fly sparge, I batch-sparged with enough water to hit my pre-boil volume, which was about 7.5 gallons. My numbers were pretty much spot-on for 71% efficiency.
Since I brewed this in March, I put the primary fermenter in my garage near the door into the house - it stayed fairly steady at about 50 degrees there. I brought it inside the house for a diacetyl rest (probably unnecessary since I wasn't using pilsner malt) and then put the secondary fermenter back in the garage, but much further away from the inside door - that dropped it to about 45 degrees.
This is DEFINITELY getting brewed again this winter. Once I get some new equipment in I'll probably try decocting this year.
