Grainfather Specifications for BeerSmith, Beer Tools Pro, and Other Software

Recently, I've been trying to "dial in" settings in BeerSmith and Beer Tools Pro so that I can do a better job getting my actual brewing results to match up to the figures in the software. Below are some of the figures I've worked out with my US Grainfather. Given manufacturing variances and possible measuring errors on my part, these might not match exactly to yours, but hopefully they're close enough that it will help you.

BeerSmith Equipment Profile:

  • Brewhouse Efficiency: 83% (based on my experience, yours may vary)
  • Mash Tun Volume: 8 gallons
  • Mash Tun Weight: 8.82 pounds
  • Mash Tun Specific Heat: 0.12 Cal/gram-deg C
  • Mash Tun Addition: 0 gallons
  • Lauter Tun Losses: 0 gallons
  • Top Up Water for Kettle: 0 gallons
  • Boil Volume: 6.25 gallons
  • Boil Time: 60 minutes
  • Boil Off: 0.40 gallons per hour
  • Cooling Shrinkage: 6%
  • Loss to Trub and Chiller: 0.53 gallons
  • Batch Volume: 5 gallons
  • Fermenter Loss: 0.40 gallons (yours may vary)
  • Whirlpool time: 0 minutes
Beer Tools Pro Vessel Profile:
  • Shape: Circular/Elliptical
  • Width: 12 inches
  • Length: 12 inches
  • Height: 17 inches
  • Capacity: 8.3 gallons
  • Heat Capacity: 1020.5 J/K
  • Dead Space; 0.5 gallons
  • Heat Transfer Coefficient: 5.51 W/m2 K
  • Environment: 68.5F
  • Infusion Volume: 5.0 gallons
  • Infusion Temp: 148F
  • Temp After 5 minutes: 147F
  • Temp After 65 Minutes: 137F
Beer Tools Pro Heat Source Profile:
  • Environment: 68.7F
  • Calibration Volume: 5 gallons
  • Vessel Heat Capacity: 502.8 J/K
  • Time to Heat 18F (10C): 10.5 minutes
If, as I do, you use hops bags to keep particulate out of the kettle, you may want to factor in adding about 10% additional hops to account for possible losses due to the bag.

2021 Batch 16/17 - Horseman's Pumpkin Ale Kit from Great Fermentations

Although there are a few pumpkin spice ales on the market that I enjoy (Hoppin' Frog's Double Pumpkin, Samuel Adams Fat Jack, and Heavy Seas Great'r Pumpkin come to mind first), I've yet to brew a pumpkin spice ale that I have been happy with.  Either I didn't feel like the base beer was quite right, or the spice mix was too "something" (insert random pie spice there) forward, it was too hop-forward, or it was wrong in some other way.  This year, I decided to try the kit from Great Fermentations in Indiana to see if I liked that any better than previous brews. Ingredients 9 pounds 2-row Brewer's Malt 1 pound Munich Malt 8 ounces Crystal 40L Malt 15 ounces Canned Pumpkin (not included in kit) 1/4 tsp. Brewtan B (my addition to kit) 1 ounce Glacier Hops 1/2 tsp. Brewtan B (my addition to kit) 1 tsp. Irish Moss (15 min.) 0.5 tsp. Ground Cinnamon (not included in kit) 0.5 tsp. Vanilla extract (not included in kit) 0.5 tsp. Pumpkin Pie Spice (not included i...

2022 Batch 01 - St. Gambrinus Spiced Holiday Ale (Kit)

I purchased a St. Gambrinus Spiced Holiday Ale Kit from Great Fermentations in Indianapolis a few weeks ago and decided to get it made today... a tad late for the holidays, but it will give me a good idea if I like the recipe for next Christmas. The kit basically comes as a bag of crushed grain with a packet of Northern Brewer hops.  You supply your own spices and order yeast separately. Ingredients 8.5 pounds Two-Row Brewer's Malt 2 pounds Munich Dark Malt 1 pound Honey Malt 8 ounces Simpsons Dark Crystal Malt 0.5 ounces Northern Brewer hops (60 min.) 0.5 ounces Northern Brewer hops (30 min.) 1 package White Labs Edinburgh Scottish Ale yeast 1 tsp. Irish Moss (15 min.) 0.5 oz. Bitter Orange Peel (10 min.) 2 cinnamon sticks (I used 3) (10 min.) 0.5 tsp. Ground Ginger (10 min.) 0.25 tsp. Allspice (secondary) 0.25 oz. Ground Cardamom (secondary) 0.25 oz. Ground Cinnamon (secondary) 1 Tbsp. pH 5.2 Stabilizer added to mash after grain 6.8 gallons of RO water, treated with: 3 grams Gyps...

2022 Batch 02 - Pecan Brandy Mead

I watched an episode of Moonshiners: Master Distiller   late in 2020 where one of the contestants made a Pecan Brandy that he (and the judges) described as being very tasty, like drinking a pecan pie.  I thought that sounded good, and although distilling it into brandy would not be a legal option for me, turning it into a mead would be quite possible and might be good. The recipe as described on the show was pretty simple... honey, water, yeast, and pecans. Ingredients 12 pounds of Wildflower Honey 2 pounds of Pecans, crushed and ground 4 gallons of water, treated with some gypsum 1 tsp. yeast nutrient 1 package of Premier Des Cotes champagne yeast Batch Size: 5.0 gallons (actual and estimated) Original Gravity:  1.090 (actual and estimated) Final Gravity:   0.984 (estimated) Brewing Instructions Bring water to a boil and sterilize wort chiller. Add half the pecans in a muslin bag.  Add the other half, in a different muslin bag, to the fermenter. Gradually add ...
