Bluntrock Yop Rock Lager
By Bluntrock · UK
A 0.5% lager from Bluntrock, in Rock on the north Cornish coast, brewed with Yops™, a yeast-derived aroma product that Bluntrock says it was the first in the UK to use. The result, it says, is “bright, citrusy and darn refreshing”.
At 0.5% ABV, this isn’t alcohol-free under UK guidance, which keeps the term for 0.05% or less. We list it with alcohol-free beers, as UK shops do. How UK labels work

What is Yop Rock?
Yop Rock is the lager in Bluntrock’s alcohol-free range, alongside Zen, a 0.5% pale ale. Its citrus character doesn’t come from fruit: we used to say it was brewed with yuzu and orange peel, but Bluntrock names no fruit. It credits Yops™, a yeast-derived aroma product developed by EvodiaBio and sold to brewers by Lallemand, which is designed to add flavour to low- and no-alcohol beer.
Bluntrock says it was the first in the UK to use Yops, and it has added Yop Rock to its core range. It says all its beers are vegan friendly and unfiltered; Yop Rock contains barley and wheat, so it isn’t gluten-free. Bluntrock doesn’t name the hops or publish a calorie figure.
Bluntrock was founded in 2021 by George Collins and Hugo Roads, and started out brewing in shipping containers in Rock. You can buy Yop Rock from its own shop and from Wise Bartender. For other lagers, see our guide to the best alcohol-free lagers.
