M&S British Craft Lager is brewed for Marks & Spencer by Harbour Brewing Company in North Cornwall. The recipe uses spring water drawn from the brewery's own hillside site, and fermentation runs at low temperatures to retain character at 0.5% ABV. The brand describes the result as crisp and citrusy in style. It sits within M&S's own-label low-alcohol beer range alongside other lager and pale ale styles.
