The British shandy is a pub staple, and St Omer's version is a well-established import that's been sitting in the Morrisons chiller for years. Brasserie de Saint-Omer, founded in 1866 in the Pas-de-Calais, calls this "Le Panaché" — the French term for the same idea: light lager blended with lemonade to produce something cold and effortlessly drinkable. It's not trying to be a craft product. The lager is brewed with barley malt and maize; the lemonade side uses sugar, inverted sugar syrup, and citric acid to get its brightness. Standard industrial formula, and it works. St Omer doesn't pretend to be anything other than a simple, low-alcohol option for people who want something cold at a BBQ without committing to a full beer. At 21 kcal per 100ml it's light, and the 10-pack pricing at Morrisons makes it one of the better-value options in the low-ABV shandy category. Worth keeping cold.
