Notes

Mini-mash flaked barley with 2-row at 152° F until converted. Add sulfate to water to achieve 40 ppm Ca++

Dilute extract and steep with RO water.

Steep dark grains in 3 qt water at 168° during mini-mash. Combine worts in kettle, dilute extract to get to 4.5 gallons of wort. Add hops to combined worts to simulate FWH.
