O'Hara's Irish Red Nitro is brewed by Carlow Brewing Company, an independent family-owned Irish craft brewery established in 1996 and a pioneer in Ireland's modern beer scene. This is a full-bodied, smooth Irish Red that delivers more character than its modest alcohol content suggests.

The aroma opens with roasted barley and a hint of toasted grain, followed by subtle fruity and herbal notes. On the palate, a substantial malt body carries flavours of toasted bread and biscuit, balanced by restrained hop bitterness and a sweet malt finish. The nitrogen carbonation creates a soft, creamy mouthfeel that makes this beer remarkably smooth and approachable.
