General Info

Inspired by Anspach & Hobday London Black.

Cold steep Carafa and add to last 15 of boil.

Regarding water: “Since you are brewing a Porter, some alkalinity is desirable in the mashing water. That will help keep the mash pH from dropping too low like it will if you use RO or distilled water. The beer flavor is improved when the wort pH is in the 5.4 to 5.6 range. With distilled or RO water, the wort pH could easily be in the 5.0 to 5.2 range. Its still going to be a good tasting beer, but may be more tart than you prefer.”
