![]() If the temperature is too high (around 168-170F), it can permanently halt the conversion process. If the mash temperature is too low, it can lead to poor starch conversion, resulting in a thin, “watery” beer.Īdditionally, mashing at a temperature much lower than the recommended range can break down essential proteins needed for head retention. What happens if the mash temperature is too low? On the other hand, mashing at the lower end produces shorter sugars, resulting in a thinner, drier beer. Mashing at the higher end of this range results in longer sugars which are harder for the yeast to consume, leading to a more full-bodied beer. ![]() ![]() The normal mashing temperature range is between 145 – 158F (63 – 70C). Mash temperature plays a crucial role in determining the outcome of your beer. Frequently Asked Questions Why is mash temperature important?

Mash too much lower than that and you’ll end up with poor starch conversion and a really thin, “watery” beer. This leaves behind a thinner, drier beer. Mashing at the lower end of the range produces shorter sugars, which the yeast will gobble right up. More sugar will be left over after fermentation resulting in a more full-bodied beer. In general, mashing at the higher end of that range produces longer sugars which are harder for the yeast to eat. We’ll get to the swift action in just a moment.įirst, know that the normal mashing temperature range is 145 – 158F (63 – 70C). ![]() The good news is it’s probably not as bad as you think, and you can mitigate the effects by taking swift action.

To my dismay, the mash temp capped out 15 degrees below target. The thermometer needle was creeping up, but slowly… too slowly. I mashed in at 163F with a target temp of 152F. As the strike water heated up, we cracked open some brewskis and played a few songs on Rock Band.
