This is a very small proportinally scaled down mash made of the same malts as the original recipe. The best way to determine mash pH is to conduct a test mash. (Of course these spreadsheets *have* done a great service to the homebrew world.)Ĭertainly data entry errors, measurement errors, accuracy errors and repeatability errors, etc. There is no spreadsheet or set of equations that can fully and accurately predict mash pH, though most do a good approximation. The DI pH is the pH of a mash made with distilled water and a small amount of a finely ground malt sample. You can calculate normality using any of the following formulae: Normality (N) (Mass of the solute) / (Equivalent mass of the solute (E) × Volume of the solution (V) ) Normality (N) W g / E g × V Equivalent weight per liter / ( W × V ) Note that in the above formulae the volume of the solution V should be in in liters. Other calculators like "Mash Made Easy" allow you to enter what is known as the DI pH of each malt. Try setting a base malt as a roast malt and look at the effect it has on the predicted pH. These coffee water calculators were inspired by the groundbreaking book. BruNwater most likely has three equations fitted to samples of base, crystal and roast malts. A collection of water chemistry calculators. The thing is some of these data points are outliers and don't fit well within the fitted equations, also each malt and worse yet, each batch is different. rainwater that falls instead of tap-water (precipitation calculator) and the energy cost when you use a. Those spreadsheet calculators operate off of equations that have been fitted to data points collected from various malt samples. Ion exchange calculator for one chemical element.
Does anyone have any logic to suggest one more accurate than the other? Just trying to get a feel for which one to trust. Last brew day though I went with the first one, added the recommended acid additions and ended up with a pH of 4.9. I guess my question is why is one calculator generating a mash pH with no acid additions of 5.28 and another says it will be 5.53? I guess it is not a terribly big deal as both are in a decently acceptable range. I have a water test kit and have gotten the following resultsīrewing tomorrow and have the following grist and goal water profile: I have looked around at other calculators and the same data entry seems to yield different results. I have been using Bru'nWater the last several batches and it seems to over estimate the addition of acid (at least in the last batch). I have been trying to dial in water chemistry a bit more accurately and have gotten some conflicting results from brewing calculators.
