This is either done in an insulated mash tun with no heat required or a kettle and heat is applied to keep the temperature steady. This procedure is ideal for the use of a converted cooler. Single infusion mashing is the easiest method, as it requires very little attention other than keeping the temperature at a steady point. While many brewers choose more elaborate methods, the reality today is that, with the refined techniques of the modern malting process, single-infusion mashes are generally adequate for converting the sugars needed for most styles.
