Is it possible to calculate my original gravity based on this recipe?

Categories: Brewery

Question:

Hello, I brewed 6 gallons of a wee heavy and was wondering, since I didnt write it down, if i can figure my original gravity based on the following recipe: 1 lb special B 2 lb vienna malt 14 pounds dry pilsner malt 2.5 ounces peated malt Please assume I was pretty efficient with the grains. Any help would be greatly appreciated. Sincerely, David Lown

Quick run through promash for 6 gallons with that, at 80% eff, 1.083 SG 75% eff 1.078 70% eff 1.073 Course, thats a guesstimate… boil off, sparge, etc…

What is dry pilsner malt? I’ve never heard of it. says… – Hide quoted text — Show quoted text -Hello, I brewed 6 gallons of a wee heavy and was wondering, since I didnt write it down, if i can figure my original gravity based on the following recipe: 1 lb special B 2 lb vienna malt 14 pounds dry pilsner malt 2.5 ounces peated malt Please assume I was pretty efficient with the grains.

Response:

The equation is easy– ((lbs of grain x extract points for grain per pound per gallon) x system efficiency) / batch size Assuming an efficiency of  80%, and an average extract potential of 37 for your malt: (the usual for Vienna and Pilsner is 37– the pound of Special B is small enough to be ignored) ((19.5 x 37) x  .80) / 6 = 1.096 That’s a pretty big beer!  Of course with knowing your exact efficiency there’s no real way to know.  Odd choice for pilsner malt in a Wee heavy, but any quality base malt would suffice.  Marc

Response:

The Special B is small, however accounts for about 5 extra gravity points , ~5%. Bill

Yes. I’m sorry its Czech Pilsner (from St. Pat’s) DME I’m pretty excited about the beer though because its been aging for 8 months in secondary and the smell is gorgeous!!!! David

David, I assume this is in reponse to my question about the nature of the Dry Pilsner malt? Is so, here are the calculations 1 lb special B 2 lb vienna malt

Assuming you mashed these and got 75% eff., they will contribute about 80 point 14 pounds dry pilsner malt

Dry malt usually yiels about 45 points, so assume 630 total points. 2.5 ounces peated malt

Not worth calculating. So, the total is 710 points, divided by your batch size = 118, or 1.118 OG

Try again.  It is 2.5 ounces of peated, not pounds… I’d use 17 lb and 36 as my theoretical if dry pilsner is just pils malt… 17 x 36 x decimalavgefficiency/6 = Points OG = 1+(Points/1000) Cheers, Mike

Response:

Whoops.  My bad.  I misread the peated as pounds, not ounces.  (Can you imagine two 1/2 pounds of peated malt?  Yuk!) So that’s ~17 lbs total grain. ((17 x 37) x .80) / 6 = 1.084 The pound of Special B would bring down the overall extract potential some, so 36 ppg might be better to use, but since we’re just estimating anyway, it’s up to you.  Cheers to beer, Marc Marc

If it’s an extract recipe, yes you can figure out what the OG was because the efficiency is fairly constant.  If it’s an all-grain recipe, then there’s almost no way you can figure it out unless you know what your brewhouse efficiency is. 14 pounds dry pilsner malt

What is this… DME? John. —                            *** John P. Kolesar ***                          *** Valley Mead Brewery ***
