Beers, lagers, ciders and wines which are described as “low-alcohol” vary enormously in strength. Some wines can be up to half the strength of ordinary table wine. Beers, lagers and ciders can vary between being a third of the ordinary strength and virtually alcohol-free (0.005% ABV). Don’t be confused by the name: “light” can refer to the colour or calorie content of a drink rather than its strength.
