I just tasted their New Belgium Ranger IPA, and it was a very good tasting beer, but it had a slight wheat beer smell to it. I believe the house yeast strain of New Belgium Brewery is a variation of American wheat. When Wyeast released Fat Tire yeast several years ago, the profile of that yeast was:
Apparent attenuation: 73-77%.
Flocculation: low.
Optimum temp: 65°-72° F
The Wyeast 1010 American Wheat strain profile is:
Flocculation: Low
Attenuation: 74-78%
Temperature Range: 58-74° F (14-23° C)
Alcohol Tolerance: approximately 10% ABV
Wyeast 1010 is definitely NOT going to be the exact same yeast strain as Fat Tire, but I believe it will definitely get you in the ballpark. If I were to make a Fat Tire clone, first I would mash the grains at about 148-150 degrees, then I'd try that yeast. The New Belgium web site lists their grains as 2Row, Munich, Victory, and C80. Go with something like 80% 2 Row, 5% Munich, 10% Victory, and 5% C80. The Goldings listed on their web site is almost certainly Styrian Goldings because East Kent Goldings is WAY too boring, and they also use Willamette; both are variations of English Fuggle. I'd bitter with a blend of those. The Target hop that they list on their website leaves a really interesting chocolate malt-type of flavor in beer when used as a late addition hop. So I'd make sure to put that in the last 10 minutes of the boil, and whirlpool with it along with some Styrian and Willamette. Hops: Styrian Goldings and Willamette 60, Styrian, Willamette, and Target for 10 minutes, Styrian, Willamette, and Target for 5 minutes, and Styrian, Willamette, and Target to whirlpool and steep for 10 minutes. The intense late hop additions are to compensate for the whirlpool that they likely use. Fermentation is the key to any beer, so I'd build a large starter, aerate the wort, and then I'd start it at 65 degrees for a few days to keep the ester profile down. Next, I'd slowly bring it up to 72 degrees over a couple of days to dry the beer out. Obviously, they cold condition, filter, and force carbonate their beer. As a homebrewer, I would bottle the beer and then let it carbonate for a couple of weeks. Then, I would lager that beer for 2-4 weeks to drop the yeast. I believe that yeast is how they get their unique flavor from their American Amber Ale. Thoughts? Has anyone ever tried this?
