Quick answerTwo UK alcohol-free beers are brewed with blends aimed at helping you unwind: IMPOSSIBREW (Social Blend, six ingredients, 1,650mg per 440ml can) and Collider (Unwind Blend, three ingredients, 400mg per 330ml can by its own account). IMPOSSIBREW has more blend per can, more named ingredients, a lower price per 100ml and far more Trustpilot reviews. Collider adds Lion's Mane and has fewer calories.

Why ordinary alcohol-free beer can feel flat

Alcohol-free beer replaces the taste of beer but not the wind-down. Functional beers add ingredients chosen for that moment. They do not contain alcohol and they will not get you drunk.

More milligrams tells you what is in the can, not how strongly you will feel it. Different blends contain different ingredients.
