I think I got the following recipe from BYO magazine in 2008. I haven't brewed it but I tasted a friend's clone and scored it 43 per BJCP guidelines at the time.
One thing I do know is that they definitely use whole hop cones, not pellets. Don't know about boil time.
Also mentioned for the recipe below is that they did NOT dry hop, at least not in 2008.
Sierra Nevada Pale Ale Clone
6.5 gallons
OG=1.053
FG=1.011
ABV=5.6%
IBU=32
SRM=7
11.5 lb Pale Malt (2-Row)
1 lb Crystal 60
0.5 oz Magnum (13.6% alpha, 60 min)
0.5 oz Perle (7.7% alpha, 30 min)
1 oz Cascade (5.8% alpha, 10 min)
2 oz Cascade (5.8% alpha, flameout)
US-05
Mash at 153 F for 1 hour. Ferment 7 days at 68 F. Dry hop IF desired, but Sierra Nevada doesn't. Carbonate as normal.
When I plug this into BeerSmith, the SRM comes out at 9.42 which is higher than the above specs and feels a little darker than SNPA and C-60 seems a little too caramel for the flavor, too. I’ve seen C-40 in some of these SNPA recipes and that feels a little closer to the color and flavor profile to me. I’m sure I’d love the above, too, and have made very similar APAs.
