What type of malt is known for being already stewed in the process?

The correct response is caramel malts, which undergo a unique process known as "stewing" during their production. Caramel malts are produced by partially mashing malted barley before drying it, allowing the sugars to caramelize. This process results in characteristic sweetness and flavors of toffee, caramel, and fruit, which are often desirable in a variety of beer styles.

Base malts, such as pale malts, provide fermentable sugars and form the backbone of many beer recipes but do not undergo the stewing process. Roasted malts, while contributing rich, dark flavors, are typically subjected to high-temperature roasting rather than stewing. Both of these malt types contribute different qualities to a beer's flavor and aroma profile, but they do not share the same production characteristics as caramel malts.
