I've checked all the things I can think of, but I'm still getting a significant difference in OG and IBU between a recipe posted on HBT and the one I've entered in BF. OG should be 1.077 and I'm getting 1.083, and IBU's should be 36 and I'm getting 47. What's especially strange is that I have efficiency set to 70% and the recipe is listed at 75%, which I would think would make my numbers lower, not higher. Here are the two recipes: HBT Version: Recipe Type: All Grain Yeast: Safale-05 Yeast Starter: Nah Batch Size (Gallons): 5 Original Gravity: 1.077 Final Gravity: 1.015 IBU: 36 Boiling Time (Minutes): 60 Color: 17 Primary Fermentation (# of Days & Temp): 3 weeks Tasting Notes: Complex malt and nicely blended spices and hop aroma Mash Efficiency: 75.0 % Fermentation Temperature: 64 degF Fermentables US 2-Row Malt 13lb 0oz (84.1 %) In Mash/Steeped UK Medium Crystal 8.00 oz (3.2 %) In Mash/Steeped Belgian Special B 8.00 oz (3.2 %) In Mash/Steeped German Wheat Malt 4.00 oz (1.6 %) In Mash/Steeped US Chocolate Malt (350L) 3.20 oz (1.3 %) In Mash/Steeped Sugar - Honey 1lb 0oz (6.5 %) End Of Boil Hops US Centennial (9.4 % alpha) 1.00 oz Bagged Whole Hops used 60 Min From End US Centennial (9.4 % alpha) 0.50 oz Bagged Whole Hops used 30 Min From End US Centennial (9.4 % alpha) 0.50 oz Bagged Whole Hops used 5 Min From End Other Ingredients Irish Moss 0.01 oz used In Boil Vanilla Beans 1 Orange Peel, Bitter 1 Tbs Cinnamon Stick 1 Ginger Root 1Tbs (dehydrated or fresh) Single Step Infusion (67C/152F) And my BF Version: HOME BREW RECIPE: Title: Holly - Christmas Ale Author: jmo88 - HBT Brew Method: BIAB Style Name: American Brown Ale Boil Time: 60 min Batch Size: 5 gallons (fermentor volume) Boil Size: 6.2 gallons Boil Gravity: 1.060 Efficiency: 70% (brew house) STATS: Original Gravity: 1.083 Final Gravity: 1.015 ABV (standard): 8.92% IBU (tinseth): 46.93 SRM (morey): 17.66 FERMENTABLES: 13 lb - American - Pale 2-Row (84.1%) 0.5 lb - United Kingdom - Crystal 60L (3.2%) 0.5 lb - Belgian - Special B (3.2%) 0.25 lb - German - Wheat Malt (1.6%) 3.2 oz - American - Chocolate (1.3%) 1 lb - Honey - (late addition) (6.5%) HOPS: 1 oz - Centennial, Type: Leaf/Whole, AA: 10, Use: Boil for 60 min, IBU: 31.63 0.5 oz - Centennial, Type: Leaf/Whole, AA: 10, Use: Boil for 30 min, IBU: 12.15 0.5 oz - Centennial, Type: Leaf/Whole, AA: 10, Use: Boil for 5 min, IBU: 3.15 MASH GUIDELINES: 1) Infusion, Temp: 152 F, Time: 60 min OTHER INGREDIENTS: 0.01 oz - Irish Moss, Time: 15 min, Type: Fining, Use: Boil 1 each - Vanilla Bean, Type: Spice, Use: Bottling 1 tbsp - Orange Peel, Bitter, Type: Spice, Use: Bottling 1 each - Cinnamon Stick, Type: Spice, Use: Bottling 1 tbsp - Ginger Root, Type: Spice, Use: Bottling YEAST: Fermentis / Safale - American Ale Yeast US-05 Starter: No Form: Dry Attenuation (avg): 81% Flocculation: Medium Optimum Temp: 54 - 77 F Fermentation Temp: 64 F I understand there can be small differences, but these values seem significantly off. Thanks for any insight anyone can offer.
