Guinness 0.0 is a zero-alcohol stout from one of the world's most iconic beer brands. This page compares them side by side.

Key Differences
Different Styles, Different Occasions
IMPOSSIBREW is an Enhanced Lager. Guinness 0.0 is a stout. That alone changes the drinking occasion. The lager is lighter and more versatile across meals, social settings and warm weather. The stout is richer and heavier, suited to colder months and pub-style drinking. This is not a like-for-like comparison, but it reflects a real decision many alcohol-free shoppers face.
Functional Ingredients vs Traditional Brewing
IMPOSSIBREW contains 375mg of the Social Blend formula, combining L-Theanine, Ashwagandha, Vitamin B1 and Magnesium. Guinness 0.0 takes a traditional approach with no functional ingredients added. Both are brewed to be alcohol-free, but IMPOSSIBREW is designed to support a relaxed, social feeling beyond just taste.
Sugar Content
There is a notable difference in sugar. IMPOSSIBREW Enhanced Lager has less than 1g of sugar per 100ml. Guinness 0.0 has 2.7g per 100ml. This is partly because fructose is added during Guinness 0.0 production to replace flavour lost during alcohol removal. For anyone watching sugar intake, this is a meaningful gap.
Alcohol Level
Guinness 0.0 is exactly 0.0% ABV. IMPOSSIBREW Enhanced Lager is 0.5% ABV, within the UK alcohol-free category. For anyone who requires strictly zero alcohol, Guinness 0.0 meets that threshold. For most shoppers, the difference between 0.0% and 0.5% has no practical effect.
What Customers Say
"I drink every night. I've done this for over a decade. Since I bought the lager from Impossibrew I have not drank on 3 nights and managed with only 2 pints for several others. All drink is now out of my house replaced with this. It seems to taste and feel best on an empty stomach. I have tried nearly every other sort. This works for me."
- IMPOSSIBREW customer, Judge.me (Enhanced Lager)
"I did Dry January with the help of Impossibrew. It's nearly March and I have no desire to drink. I love an Impossibrew lager when I'm cooking dinner. It definitely makes me feel calmer when I get in from work."
