Do the mash.

Well, I've now brewed my first all-grain recipe. I built a mash/lauter tun out of a 5 gallon cylindrical water cooler, a stainless steel false bottom, and the following (inside to out):

3/8" hose barb to 1/2" MIP
1/2" FIP to 3/4" male hose
3/4" female hose to 3/4" MIP
(Cooler wall)
#17 rubber O-ring (#15 would have been better)
3/4" ID washer (2" OD, milled to 1.75" to fit the cooler)
3/4" FIP to 1/2" FIP reducer
1/2" x 1.5" MIP nipple
1/2" ball valve (threaded 1/2" FIP both sides)
3/8" hose barb to 1/2" MIP

Toss in some vinyl hose, teflon tape, and a trio of clamps, you've got yourself an all-grain setup. It's fun to build, but not really worth the time. I spent about $75 ($20 for a new cooler, $25 for the false bottom, $30 for other parts), which is only about $10 less than a new complete assembly from MoreBeer.

For my first recipe, I borrowed Jim Rossi's Honey Pale Ale from MoreBeer's library.

Batch #15
Jim Rossi's Honey Pale Ale
--7 lbs 2-Row American Pale Ale Malt
--8 oz Honey Malt (Crystal 25L)
--3 lbs Honey (15min)
--0.5 oz Cascade 7.4% AA (60min)
--0.5 oz Cascade 7.4% AA (1min)
--Whirlfloc (20min)
--White Labs WLP001 Calif. Ale Yeast
OG: 1.054
FG: 1.004!!!
ABV: 6.5%
Calc. IBU: 15ish

Mashed 1 hour at 152°F with 2 quarts per pound. Batch sparged to 6 gallons. Mash gravity was 1.035. My calculations bring that to about 74% efficiency. I used whole hop leaves for this one.
