I have not liked either of the two beers I've made with Red X even though I have liked commercial beers with large amounts in the grist. I finally jumped aboard the pH meter bandwagon and tested my batch of Red X and it came in at 5.17 or so. Fudging the color in Bru'n water tells me that my mash pH was 4.95 for one and 5.1 for the other. Could certainly explain why the beers were awful.
So I'm going to need to try another Red X based beer very soon.
Anybody else notice this?
I just brewed a 100% Red X single malt American Strong Ale last night. My water profile is such that I have to add only a 1/2 tsp of gypsum to get a "perfect" water profile for this style. My water pH was 7.5, and pre-boil, I had a pH = 5.6. I have tasted the Red X malt straight from the bag and it does not taste acidic or tart. It tastes like warm baked biscuits, malty, and sweet. From what others have posted, I have noticed that if the starting brew water pH was <6.5, there were issues with the final beer taste. I tasted my wort after cold-crashing but before pitching yeast, and it tasted pretty damn good. Can't wait to taste the final product.
