Scale this commercial recipe to homebrewing?
« on: January 31, 2013, 08:02:05 AM »
This recipe is from the Briess website.  How would I scale the ingredients down to a homebrew size recipe?  I do 3 gallon BIAB.


Sierra Nevada Black Vapor

This collaboration beer was brewed on Sierra Nevada's 10 BBL pilot brewery in Chico, CA for the 2011 Craft Brewers Conference in San Francisco. This "steam" style hybrid beer was a nod to the rich brewing heritage at Anchor Brewing Co. though with a twist by darkening up this style with Midnight Wheat malt!

They give OG, so divide that by the potential extract of the grist and your efficiency to get the total grist weight, then keep the malts proportionate.

For example, at 65% efficiency: 13.2°P * 3 gal / (9.2 °P-gal/lb * 65%) = 6.62 lb
C40: 6.62*50/528 = 0.63 lb

For hops, it's a 10 bbl recipe, so divide by 110, give or take. Without knowing AA% that's the best you can do.

That's the potential extract for malt, or at least a reasonable average.

I dumped the original recipe into Brewers Friend, then tweaked the efficiency percentage and the "additional boil time" (intended for No Chill brewers, but also helpful for this purpose) until I got the OG and IBU's to match the reported values:

HOME BREW RECIPE:
Title: SN Black Vapor

Brew Method: All Grain
Style Name: California Common Beer
Boil Time: 90 min
Batch Size: 315 gallons (fermentor volume)
Boil Size: 400 gallons
Efficiency: 89% (brew house)
No Chill: 4 minute extended hop boil time

STATS:
Original Gravity: 1.054
Final Gravity: 1.014
ABV (standard): 5.32%
IBU (tinseth): 32.31
SRM (morey): 26.25

FERMENTABLES:
420 lb - American - Pilsner (79.7%)
50 lb - American - Caramel / Crystal 40L (9.5%)
25 lb - American - Munich - Light 10L (4.7%)
32 lb - American - Midnight Wheat Malt (6.1%)

HOPS:
16 oz - Magnum for 90 min, Type: Leaf/Whole, Use: Boil (AA 12.2, IBU: 12.3)
24 oz - Northern Brewer for 60 min, Type: Leaf/Whole, Use: Boil (AA 7.8, IBU: 11.14)
24 oz - Northern Brewer for 15 min, Type: Leaf/Whole, Use: Boil (AA 7.8, IBU: 6.43)
32 oz - Aurora for 0 min, Type: Leaf/Whole, Use: Boil (AA 8, IBU: 2.44)

Then I scaled it to a 3 gallon batch size, and scaled it one more time down to 75% efficiency. Here's what I get for a 3 gallon batch:

STATS:

ABV (standard): 5.29%
IBU (tinseth): 32.84

FERMENTABLES:
4.85 lb - American - Pilsner (82.1%)
0.48 lb - American - Caramel / Crystal 40L (8.1%)
0.28 lb - American - Munich - Light 10L (4.7%)
0.3 lb - American - Midnight Wheat Malt (5.1%)

HOPS:
0.15 oz - Magnum for 90 min, Type: Leaf/Whole, Use: Boil (AA 12.2, IBU: 12.35)
0.23 oz - Northern Brewer for 60 min, Type: Leaf/Whole, Use: Boil (AA 7.8, IBU: 11.44)
0.23 oz - Northern Brewer for 15 min, Type: Leaf/Whole, Use: Boil (AA 7.8, IBU: 6.6)
0.3 oz - Aurora for 0 min, Type: Leaf/Whole, Use: Boil (AA 8, IBU: 2.45)

To address the additional boil time, the safest thing is probably to boil each of your additions (except flameout) for an additional 4 minutes. You could also do a hop stand or hot whirlpool after the boil, but how long you'd need would involve some trial and error. Actual amounts of your hops would change based on the AA% as well.

Excellent, thanks for the help!
