Classic Scotch whisky cocktail; alcohol and vermouth sugar make it a notable gout flare risk.
The Rob Roy is a classic cocktail built from Scotch whisky, sweet vermouth, a dash of bitters, and a cherry garnish [3]. The dominant ingredient, Scotch whisky, is typically 40% alcohol by volume [1], and a standard Rob Roy serving delivers roughly 1.6 standard alcoholic drinks [2]. This concentrated alcohol is the main gout hazard.
Alcohol raises blood uric acid in two ways: it speeds up the purine breakdown that produces uric acid, and it impairs the kidneys' ability to excrete uric acid. Even modest amounts can trigger an acute flare, especially in people who already have elevated uric acid. The whisky portion alone is enough to move the needle.
Sweet vermouth contributes added sugar — about 2 g per serving and 6 g of total carbohydrates . While modest, sugar (especially fructose) can also raise uric acid by boosting purine metabolism. Combined with alcohol, the effect is compounded.
A Rob Roy is best avoided during a flare or when uric acid is poorly controlled. If you do choose to drink, limit yourself to one small cocktail, sip slowly, and pair it with plenty of water. Skip the drink entirely if you are on diuretic medication or have a history of frequent attacks. Overall calorie load varies from roughly 179 to 278 kcal depending on proportions [2], so this is not a light drink by any measure.
