OK. I'm confused...

This group is great, and I thought I had this thing liked (of course, I did!

)

Used the above recipe. Bought water (refill machine at grocery - Culligan was the make of the machine).

Mash tun made from 10 gallon rubbermaid round cooler.

60min with grains, hit a little low ~148 intended 1.4 Q/lb.

Added boiling water - probably went to about 1.8Q/lb. to hit 153 degrees.

PH of the wort near the end showed slightly lighter than 5.0 on the test strips.

Vourlaffed (sp?) w/ 2 beer pitchers - got pretty clear.

Sparged w/ 170 degree water - dip from pot and pour onto pie tin to keep from upsetting the grain bed. Kept ~ 1-2 inches of water over grain bed (tried, anyway).

Got about 8 gallons into the boil pot - wanted to finish the boil w/ 6.5 gal originally, ended up with 6 gallons.

.4 Warrior 15.8% pellet at initial boil

1oz Perle 7.9 leaf after 15 min

1oz Cascade 6.3 pellet after 60 min

1tsp supermoss after 65 min

1oz cascade 7.4 leaf after 70 min

Flameout at 75.

Cooled relatively quickly w/ immersion chiller (~15 min)

Per the software (reciprocator 2.2) should have ended up w/ 1.066. Actually ended up with 1.052.

Looks like ~ 54% efficiency.

Can anyone tell me what I might have done wrong?

Thanks,

Dave

PS> I STILL MADE BEER!!!
