Why per 100ml

A 440ml can of a 12 kcal beer is 52 kcal. A 330ml can of a 15 kcal beer is 50. Per can, they look the same; per 100ml, one is a fifth lighter. Always compare per 100ml.

Calories are not the only thing in the can

Only three beers here add functional ingredients: IMPOSSIBREW (Social Blend: L-theanine, ashwagandha, magnesium citrate, citrus extract, vitamin B1, soluble plant fibre), Collider (L-theanine, Lion's Mane, ashwagandha) and Erdinger (sold as isotonic with vitamins B9 and B12).
