Possibly still on sale in Lidl, £1.49 500mls, this is from Shepherd Neame and its their 4% abv Double Stout with the Master Brewer label.
Almost black, but very transparent, light coffee cream head. Its ticks most boxes with its aroma, coffee, chocolate, roast malts. First taste though and my mind immediately focuses on its body, its quite light and thin, the carbonation is fine but just the thinness strikes you.
Anyway what about the rest? Well its got dryness, coffee and chocolate, a lingering metallic note. Quite bitter coffee noted.
All in all its okay, not great just okay and drinkable.
