IMPOSSIBREW vs BrewDog Mello | Functional Beer vs Craft AF
IMPOSSIBREW Enhanced Lager and BrewDog Mello are both marketed as alcohol-free beers that support a more relaxed drinking moment, but they are very different products. IMPOSSIBREW is a traditional-style clean lager brewed in the UK with a 375mg Social Blend combining L-Theanine, Ashwagandha, Vitamin B1 and Magnesium. BrewDog Mello is a very new 0.0% fruit-forward release from Scotland, built around magnesium plus botanical extracts like balm and chamomile, with flavours such as Peach & Passionfruit and Lime & Mint. If you want a classic lager-style beer with a broader nootropic formula, IMPOSSIBREW and Mello serve different use cases.

Key Differences
Functional Formula
Both products sit in the functional alcohol-free category, but the formulas are not equivalent. IMPOSSIBREW uses a four-part Social Blend with L-Theanine, Ashwagandha, Vitamin B1 and Magnesium (375mg total) designed as a complete relaxation-focused stack. BrewDog Mello uses magnesium plus balm and chamomile extracts, but does not include L-Theanine, Ashwagandha or Vitamin B1. In short, Mello has a lighter botanical approach while IMPOSSIBREW has a more comprehensive nootropic formula.
Taste and Style
Style is one of the biggest practical differences. IMPOSSIBREW Enhanced Lager is built to taste like a clean, crisp traditional lager. BrewDog Mello is fruit-forward, sold in Peach & Passionfruit and Lime & Mint flavours. That means Mello may suit people who want a softer flavoured novelty profile, while IMPOSSIBREW is usually a better fit for drinkers who want a classic beer-style experience.
The Relaxation Factor
Both brands talk about a calmer drinking moment, but they approach it differently. IMPOSSIBREW combines multiple pathways in one formula: L-Theanine for calm focus, Ashwagandha for stress support, Vitamin B1 for normal nervous system function, and Magnesium for fatigue and psychological function. BrewDog Mello leans mainly on magnesium and calming botanicals. IMPOSSIBREW also has a longer user track record, with 84% of customers reporting they feel genuinely relaxed.
Dietary and Transparency Considerations
IMPOSSIBREW Enhanced Lager is gluten free and publishes clear calorie data (15 kcal per 100ml). BrewDog Mello is not gluten free because it contains malted barley, and its calorie content is not currently disclosed on BrewDog's website. For shoppers with dietary requirements or those tracking macros, IMPOSSIBREW is the clearer and more transparent option in this comparison.
Track Record
IMPOSSIBREW has established social proof with 1,229 reviews averaging 4.7/5. BrewDog Mello only launched in December 2025 and currently has a much smaller and more mixed early rating base (around 3.0/5 on Untappd from 139 ratings). New products can improve quickly, but today the consistency gap is meaningful.
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/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."
