Four Peaks updated their website with LOTS of information. SRM, IBU, malt bills and hops used for all their beers.
I've come up with a clone recipe for Kilt Lifter, and have some good info for the Arizona Peach.
AZ Peach: 2SRM, 9IBU, 4.2% ABV.
Grains: 2-row, Carapils, and White Wheat
Hops: Magnum
The recipe is easy other than the Peach, I would do:
5.5gal, Assuming 82% eff:
4.5lbs 2-row
2.5lbs White Wheat
.5lb carapils
Mash at 149-150
0.5oz Magnum hops @15min
Safale US-05 or S-04
The peach is the tough part, I'm not sure if it's an extract or puree (tastes like extract to me). The carapils will add some sweetness to balance the tart puree if you choose to go that route.
Kilt Lifter clone(I've yet to brew this, but I think it will be dangerously close).
5.5gal, 82% eff(scale as needed).
9lbs 2-row
1lb Crystal 80L
.5lb CaraPils
2.5oz Roasted Barley
Mash @ 152
1oz East Kent Goldings @ 60
1oz East kent Goldings @ 15
Safale S-04
Targets: OG: 1.060 FG: 1.014 ABV: 6.0% IBU:22 SRM:16
The Target OG and FG are the hard part. My guess is Kilt Lifter attenuates nicely and has plenty of Crystal 80 and carapils to give body. It's possible there's less Crystal, more Roasted Barley, and a Higher OG and FG. But I think that clone should be close. I'll be brewing it in a month or two.
