Foreign Extra Stout is the stout style that gets almost no attention from craft beer writers despite being the most widely drunk stout in the world by volume, Guinness Foreign Extra Stout is available in over 150 countries and is the dominant Guinness product in India, Nigeria, and the Caribbean. I’ve brewed FES as a homebrewing project specifically to understand what distinguishes it from standard dry stout, and the higher gravity, more intense roast, and slight Brett character of traditional versions is genuinely fascinating.
Foreign Extra Stout style guide: the tropical export stout
Style overview: Foreign Extra Stout (FES) is a stronger, more intensely flavoured export version of Irish Dry Stout, originally developed for export to tropical markets (the Caribbean, West Africa, Asia, India) where higher alcohol provided stability during long sea voyages and hot climates. Guinness FES was first brewed in the 1800s as “West India Porter” and evolved into the current FES product. BJCP style parameters (16D): OG: 1.056–1.075. FG: 1.010–1.018. ABV: 6.0–8.0%. IBU: 30–70 (moderate to very high). SRM: 30–40 (very dark brown to black). Flavour profile: FES is more intense than dry stout in all dimensions: more roast character (coffee, dark chocolate), higher bitterness (sometimes approaching aggressive), more body from the higher gravity, and slightly more residual sweetness than dry stout (but still notably dry for a beer of this strength). Traditional Guinness FES has a subtle Brettanomyces character from aging with a small proportion of soured, Brett-fermented “stale” beer, this adds a slight winey, leather, or subtle funky note that distinguishes traditional FES from simply being a strong dry stout. Grain bill for 20L: Pale malt (Maris Otter): 5.5 kg. Roasted barley: 700–800g (significantly higher proportion than dry stout, 12–14% of grist). Flaked barley: 400g. Crystal 40L: 200g (small amount for some body). Target colour: 32–42 SRM (very dark to black). Total approximately 6.9 kg for OG 1.065. Hops: Target IBU: 40–60. East Kent Goldings or Challenger: 70–90g at 60 minutes. The very high hop rate is critical to FES, it provides balance against the intense roast and the significant malt body. Yeast: Wyeast 1084 (Irish Ale) or WLP004. Primary fermentation with clean ale yeast at 18–20°C. Optional Brett addition for traditional character: add Brettanomyces bruxellensis (White Labs WLP650 or Wyeast 5112) to secondary fermentation at a small rate (10–20% of a standard pitch) after primary is complete. Allow Brett secondary for 4–8 weeks at 20°C. The Brett adds subtle complexity without making the beer a sour, FES Brett character is a background note, not a defining sour flavour. Packaging and stability: FES’s higher gravity makes it naturally more shelf-stable than dry stout. Bottle-conditioned FES can improve and evolve for 2–3 years. Traditional export FES was brewed high-gravity at home in Ireland and then watered down to serving strength at destination, the homebrewer version at 6.5–7.5% is appropriate to serve at full strength. Indian homebrewing context: Guinness FES is widely available in India (in cans and bottles at liquor stores). It’s worth buying a can to taste as your benchmark before brewing. FES was specifically designed for tropical climates, the higher alcohol and robust flavour profile are well-suited to Indian beer culture and hot-weather serving conditions. FES at 6.5% ABV is significantly stronger than standard Kingfisher or Heineken (5.0%) and delivers more character per unit of alcohol. Roasted barley in the quantities required (700–800g) is the primary ingredient cost, available affordably from Indian homebrew importers and some health food stores.
Common Questions
Why does Guinness FES have a slightly sour or wine-like character compared to Guinness Draught?
The subtle sour, wine-like, or slightly funky character in traditional Guinness Foreign Extra Stout (and some versions of Guinness Extra Stout) comes from the intentional blending of a small proportion of aged, Brettanomyces-conditioned “stale” beer into the fresh-brewed base stout, a brewing practice dating to the 19th century that Guinness has maintained selectively in certain markets and products. The historical practice: Guinness historically maintained large oak vats of sour, Brett-fermented “stale” porter that were blended at approximately 3–5% of the batch volume into fresh “sweet” stout. This practice was borrowed from the London porter tradition (where blending new and old beer was standard) and provided complexity, acidity balance, and a distinctive signature. The modern Guinness FES has retained this character in some regional formulations, particularly the versions brewed in or distributed to Nigeria, the Caribbean (Jamaica, Trinidad), and some Asian markets. The character: Brettanomyces produces compounds including 4-ethylguaiacol (smoky, spicy), 4-ethylphenol (barnyard, leather, earthy), and acetic acid in small amounts. In the FES proportions (3–5% of blended volume), these compounds produce a subtle complexity, a slight winey, dried-fruit, or leather note, without making the beer a sour beer. For homebrewers: replicating this at home: produce a 5% proportion of Brett-conditioned sour stout (ferment 1L of the same stout wort with WLP650 Brettanomyces for 6–8 weeks at 20°C) and blend it into your 20L main batch at bottling. Alternatively, add a small amount of lactic acid (1–2 mL of 88% lactic acid per 20L) to simulate the slight acidity of the aged fraction without full Brett fermentation. The blending approach is truer to tradition. Note: not all commercial Guinness FES retains this character, the version sold in Ireland (Guinness Extra Stout) and some other markets has had the Brett fraction removed in modern reformulations. If you want the traditional FES character, the homebrew approach with a Brett fraction is the most direct path.
