    For water additions, we use chalk to raise the pH of the mash to 5.3-5.4. Any other additions depend on the source water.

    Mash at 152° F for 60 minutes. Target OG is 1.100.

    The bittering addition can be subbed out with pretty much anything, but we use a high-alpha hop to minimize wort losses in the kettle.

    Pitch yeast at 65° F, rising to 67° F by the end of fermentation.
