What is the typical range for mash temperatures in brewing?

The typical range for mash temperatures in brewing is between 145°F and 155°F. This temperature range is chosen because it allows for optimal enzyme activity during the mashing process. Specifically, temperatures within this range favor the activity of alpha-amylase enzymes, which break down starches into fermentable sugars, contributing to the overall efficiency of sugar extraction from the malt.

Mashing at these temperatures helps create a balanced wort with good sugar content, which is essential for fermentation. Higher temperatures within this range can lead to a more dextrinous wort, resulting in a fuller body and slightly sweeter beer. Conversely, lower mash temperatures, while effective for producing lighter-bodied beers, can lead to a less complex flavor profile.

Other ranges mentioned, such as 130-150°F and 160-170°F, could be used for specific styles or techniques but are not typically the standard for general brewing practices. The 175-185°F range is too high and generally employed for mash-out, a process occurred after the main mashing phase, designed to stop enzymatic activity and improve the efficiency of sparging, rather than for the primary mashing phase. Thus, the 145-155°F range is recognized as the optimal range for mashing, balancing
