Please Check My Calculator Results - Do I Understand This?

Post #1 made 14 years ago
Planning out my second BIAB batch based on a recipe I found randomly online. I searched for something similar to the Great Lakes Christmas Ale.

Original Recipe:

Size: 5 gal
Original Gravity: 1.077 (1.000 - 1.100)
Terminal Gravity: 1.019 (1.000 - 1.100)
Color: 12.19 (0.0 - 50.0)
Alcohol: 7.67% (0.0% - 10.0%)
Bitterness: 21.0 (0.0 - 50.0)

Ingredients:
12.0 lb 2-Row Brewers Malt
.75 lb Midwest Wheat Malt
.75 lb Crystal 45
.25 lb Special Roast Malt
.25 lb Roasted Barley

1.0 lb Honey at Flamout

2.0 tsp Cinnamon (stick) - added during boil, boiled 0.0 min
2.0 tsp Ginger (fresh) - added during boil, boiled 0.0 min

1 oz Hallertau (4%) 60 min
1 oz Cascade (5%) 30 min
0.5 oz Cascade (5%) 10 min
0.5 oz Cascade (5%) 5 min

Yeast: Wyeast 1028

---

Entering all that gave me a percentage grain bill of:

80% 2-Row Brewers Malt
5% Midwest Wheat Malt
5% Crystal 45
1.67% Special Roast Malt
1.67% Roasted Barley
6.67% Honey

I then scaled that to a 19 Liter "Brew Length" 1.077 OG with my 15 Gal Blichman straight-sided kettle with 39.68cm diameter. The boil-off from my first BIAB matched extremely closely with what the calculator predicted.

With me so far? Assume I did the same as above for the hop bill. I can go into further detail if there are questions.

So my final recipe from the calculator looks like this (measurements are now in grams):

6081g 2-Row Brewers Malt
380g Midwest Wheat Malt
380g Crystal 45
127g Special Roast Malt
127g Roasted Barley
507g Honey

28.3g Hallertau (60 Mins)
28.3g Cascade (30 Mins)
14.2g Cascade (10 Mins)
14.2g Cascade (5 Mins)

36.65 liters of water to start with.

Calculates out to 21.6 IBUs and everything is happy? Do I seem to have this correct or did I miss something?

I most sincerely appreciate the help. I want to try to really understand The Calculator.

Not sure if the Calculator handles the Honey addition properly.

But basically, the original recipe is very similar in volume to yours, so it looks about right to me.

For what its worth, I banged this into BeerSmith2 and came up with this, when I scaled it to my 50L pot (40cm diameter)

I think you meant 1.037? If not, you should check your resources :shock: How to Brew says 1.038.

Whoops! Lesson learned in proof reading :headhit:

Definitely 1.037 = one pound in 1 gallon water

NOT 1.007 ------->lol!

If how to brew says 1.038 then go with that too. I've generally seen values that can range from 1.036-1.040 but I take the values that are about in the middle, maybe a bit more conservative- I don't mind having a point or two over my OG.

However, having said all that, my typo brought up a tricky point in that if one pound of honey was added to a boil with a final boil volume of 5 gallons, wouldn't the total SG increase only be around 1.007-1.008? :think: So, could I say a 1.040 5 gallon beer recipe with one pound honey added at end of the boil would equate to 1.048?
