- Sparge temperature should be around 165 °F - 172 °F. Much higher and tannin extraction becomes an issue.
- Stop collecting wort if pH rises above 6.0. Too much tannin extraction occurs above this. Keep an inch layer of water above your mash bed to avoid a compacted mash and a possible stuck sparge.
- Sparge at a rate of about 1 qt./min. Sparging too fast will compact the grain bed and decreases the efficiency.
- Stop sparging when the specific gravity of your runnings is below 1.008.
