hey folks planning to brew my first Irish stout later this week being modeled after this recipe from zymurgy in Nov/Dec 2013:
https://www.homebrewersassociation.org/homebrew-recipe/brun-dry-stout/
Looking at the listed instructions, if I do a full volume biab mash in about 7.75 gallons of 100%ro water, omitting the roast barley until the end the mash, my resulting room temp mash ph is 5.43 with a 3.75oz acid malt addition.
Does this seem like too much acid malt for a dry stout? Should I add even more to further acidify? When exactly should I add the roast barley? I was thinking the last 10-15 mins of the 60 min mash.
How does this resulting water profile look with 4g gypsum and 2g cacl added to my mash water?
Ca 50
Mg0
Na0
Cl 33
So4 76
Is the amount of so4 too aggressive for this style? I figured it could accentuate the dryness of the style.
I'm also a bit concerned yeast health wise with the calcium barely being >50 ppm. When I followed Martin's guideline to add 2g of gypsum and 1.7g cacl per 8 gallons ro water, these mineral values seem too low to me.
Thanks in advance! Excited to try this style for the first time.
