Forged Irish Stout vs O'Hara's Leann Folláin

Side-by-side comparison · Published 27 April 2026 · 6 min read

The honest comparison most marketing copy avoids. Forged is a 4.2% nitro Irish dry stout with a celebrity brand. Leann Folláin (Irish for "wholesome ale") is the 6.0% flagship craft Irish stout from Carlow Brewing Company, the only one of the four heritage Irish stout-producing companies still independently Irish-owned. They are not in the same weight class, and that's exactly why the comparison matters.

How they taste

Forged is the smooth, low-bitterness session option. Leann Folláin is something else entirely — a complex, layered, robustly bitter Irish dry stout that announces itself the moment it hits the glass. The chocolate notes are darker; the coffee character is fuller; the hop bitterness is genuinely present (a rarity in modern Irish dry stouts); and the 6% ABV gives it a body and warmth Forged simply doesn't have access to at 4.2%.

Drinking them in sequence is instructive. Forged drinks like a session stout brewed to fit the nitro-Guinness template. Leann Folláin drinks like a stout brewed by people who care about stout for its own sake. The difference is not subtle.

The verdict

Forged vs O'Hara's Leann Folláin

Different weight classes — Leann Folláin wins on every metric except availability

If we're scoring purely on the beer in the glass, Leann Folláin is in a different league: more flavour, more layers, more honest brewer-led identity. Forged's only structural advantages are its lower ABV (genuinely useful for some occasions) and its broader supermarket distribution. If you've never had Leann Folláin, treat the next twelve months of stout-buying as your chance to fix that. Carlow Brewing has been the standard-bearer for Irish craft stout for thirty years, and Leann Folláin is the best contemporary expression of the Irish dry-stout tradition you can put on your kitchen table.
