Low alcohol beer

Step Mash Method
Step from below 50°C to over 73°C by adding boiling water over a short period of time. The low step increases the protein content (required for fermentation) and the high step causes rapid inactivation of maltose-producing beta amylase. This creates a wort with a very low attenuation limit. Make sure that the mash does not drop below 73°C after increasing the temperature.[1] See Mashing.
In making low-alcohol beers it is usual to mash well-cured malts with caramel malts at high temperatures to minimize saccharification, and so reduce the production of fermentable sugars.[2]
