Green’s Discovery Amber Ale Review: The Beer That Started Modern Gluten-Free Brewing

4.3/5
The beer that arguably started modern gluten-free craft brewing in 2003, and it still tastes like a proper medium-bodied amber ale rather than a specialty substitute.

Green’s has a real claim to being the origin point of modern gluten-free craft beer. Founder Derek Green was diagnosed with coeliac disease and, unhappy with the gluten-free beer available at the time, worked with Belgium’s DeProef Brewery to brew Discovery Amber in 2003 using millet, buckwheat, brown rice and sorghum instead of barley. It is widely credited as the first European gluten-free beer, and it is brewed with a classic Belgian ale yeast strain rather than treated after the fact.

How It Tastes

It pours a deep amber-copper with a decent tan head for a gluten-free beer. The aroma is herbal and hop-forward with a caramel edge underneath. On the palate it is medium-bodied with real caramel and nut character, a subtly fruity note from the Belgian yeast strain, and a refined, dry, herbal finish. It is one of the very few gluten-free beers that could be mistaken for a standard craft amber ale in a blind pour.

If someone doubts a gluten-free beer can taste like a proper craft amber ale, this is the one to hand them.

  • Real caramel and nut character, closer to a standard craft amber ale than most gluten-free options

  • Historically significant as one of the first dedicated gluten-free beers on the market
Cons
  • Pricier and less widely stocked than mainstream options like Redbridge
  • 6.0% ABV and a fuller body make it less of an everyday session beer
  • Import-style distribution means availability varies by region

Who It’s For

The pick for a gluten-free or coeliac drinker who wants a beer that genuinely competes with standard craft amber ales on flavor, not just on being safe to drink.
