Some of my IPA's have had a astringent off flavor.
My unaltered water profile is:
76 ppm Ca - Calcium
36 ppm Mg Magnesium
39 ppm Na Sodium
76 ppm Cl Chloride
42 ppm SO4 Sulfate
340 ppm CaCO3 Alkalinity
I have used up to 4 grams of Gypsum & 6ml of 88% Lactic Acid for a 6 gal batch. My system works best with a 1.75 qt/lb mash consistency.
What should I do differently to adjust the PH and Alkalinity?
Sample Grain bill:
Grain:
9.0 lbs Base (2-Row)
3.9 lbs British Golden Promise
1.1 lbs English Medium Crystal
.75 lbs Aromatic Malt
0.2 lbs Roasted Barley
Sample Hops:
0.6 oz Amarillo Gold 60 min
2.0 oz Warrior 60 min
2.4 oz Amarillo Gold 0 min
