Hello, I brewed an American IPA a week ago and would like anyone's opinion on how to better manage gravity when I brew next week. I used this recipe: https://www.beercraftr.com/1-gallon-american-ipa-recipe/ The OG at the end of the mash was catastrophic: 1.020 (target was 1.070). Since I measured when the temp was around 150F, the OG was no doubt higher (1.030??), but I didn't do the calculation at the time. I was expecting low efficiency with BIAB, so I had DME on hand. I calculated that I needed 600 grams (eek!) but added just 500 because it already seemed like too much. Needless to say, I overshot the target OG. I measured after the boil and it was at 1.080 (at 70F). I have grains for the next three batches that were already milled (the LHBS wouldn't grind for BIAB or run it through twice). So, next time, I will make these adjustments: add more grain than in the recipe. but how much more would you suggest? do a proper mash out (I skipped the step in the first batch) the recipe called for 9.25l of strike water for the mash. perhaps I should mash in, say, 7l of water and sparge the BIAB at 170F at the end of the mash with 2.25l? Should I check the OG before the boil? If necessary, should I add DME before or after the boil? The final gravity target is 1.015. Since there is not actually that much beer, I am hesitating to test OG several times, but suppose I have to in order to find the correct moment to bottle it up. Or, would it be safe to leave it in the fermenter 3 weeks, without testing OG, and try to bottle? If my starting OG was 10 points above the target, will my FG also be 10 points above the target? Here's next week's brewday recipe: https://www.beercraftr.com/1-gallon-american-pale-ale-ii/ Thanks for any tips!
