Tried the mixed box first

Tried the mixed box first, really enjoyed the feeling of liking a low alcohol beer. Felt relaxed at the end of the evening and great in the morning. Tried the triple hop next, excellent flavour. Always serve Really cold, it does enhance the flavour.

How we ranked them

We scored each beer on taste awards, Trustpilot rating and review volume, price per 100ml on its cheapest standard pack, calories per 100ml, and what is in the can. Price is per 100ml because cans range from 330ml to 440ml, so a per-can price flatters the smaller can. Only brands with over 1,000 Trustpilot reviews are ranked on Trustpilot.
