1/5/2024 0 Comments Beersmith estimated mash phA rough rule of thumb is to use around 60% of what the program estimates you will need for acid. A proper mash pH contributes to better flavor, complete conversion, and improved long term stability. I and others have written extensively on the importance of controlling your mash pH and maintaining it in the range of 5.2-5.6 during the sugar conversion step. Since the model the program uses overestimates the buffering capacity of the wort, the program does calculate more acid than is actually needed. This is a devilishly complex question as you want to adjust your mash pH quickly if brewing with modern malts. You can then, by entering the estimated mash pH or measured mash pH in the mash tab, get an estimated amount of acid to add to adjust the mash pH to your indicated target. SilverTree American Pale Ale Sparge Temperature: 168.1 F Tun Temperature: 153.0 F Adjust Temp for Equipment: TRUE, Mash PH: 5.55 Mash Steps. It does try to match the water profile you tell it you want and then tries to calculate the impact the minerals have, in combination with your water profile and the grains being added, on your mash pH. The program does NOT adjust the mineral content to reach a pH level. It will try to use one of those to attain the Bicarbonate level which is indicated in your target profile. The model used in the software has only two sources of carbonates: Baking soda and Calcium carbonate. The pH strips that I use are next to useless (for me at least) as I can't clearly tell the difference. ![]() The program is adding baking soda most likely because the water profile you told it to match has a Bicarbonate level around 43 ppm and your base water only contains 13.2 ppm. I wonder how accurate and reliable the mash pH estimation in this software is assuming we dial in all needed water parameters (my water supplier does provide pretty precise chemistry details). Let's start with this: BeerSmith does not think anything that you do not tell it to. Heat full volume of brewing water water to 7F above target strike temp Transfer all water to MLT to pre-heat for 3 minutes Mash-in, stir to reach mash temp.
