Glen Marnoch Islay Single Malt | Whisky Review

In the world of supermarket whiskies, few bottles spark more curiosity than Aldi’s Glen Marnoch range. While many budget-friendly options disappoint, their Islay expression has quietly developed a cult following among whisky enthusiasts seeking affordable peated malts. But does this modestly priced dram truly deliver the authentic Islay experience?

Glen Marnoch Islay | Tasting Notes

---

• Nose: Peaty, Wood smoke, Maltiness
• Pallet: Peat, smoke
• Finish: Dry Smokiness

What Is Glen Marnoch?

Glen Marnoch isn’t a distillery but rather Aldi’s own-label Scotch whisky brand. The name itself may be fictional, but the liquid inside is genuinely Scottish single malt, sourced from established distilleries. Aldi maintains secrecy around the specific source, though speculation among whisky enthusiasts suggests it may come from one of the larger Islay distilleries such as Bowmore or Caol Ila.

The Islay edition specifically captures the distinctive character of Scotland’s most famous whisky-producing island, known for its bold, peaty expressions.

Tasting Notes

Appearance: Rich amber with golden highlights and good viscosity that leaves slow, defined legs on the glass.

Nose: Immediate maritime peat smoke greets you, but it’s more measured than overwhelming. Behind the initial smokiness lies surprising complexity: sweet caramel, toasted nuts, and hints of dried orchard fruits. A subtle medicinal note emerges as the whisky breathes, revealing its authentic Islay heritage.

Palate: The mouthfeel is richer than expected at 40% ABV. The peat is well-integrated, bringing campfire smoke without overwhelming the palate. That signature nuttiness mentioned in Aldi’s press release is definitely present – think toasted almonds and walnuts – balanced by sweet vanilla, baking spices, and a touch of dark chocolate.

Finish: Medium to long, with the smoke gracefully fading while leaving warming spice and a pleasant oak dryness. The sweetness persists just enough to balance the smoky character.

Key Specifications

• ABV: 40%
• Category: Islay Single Malt Scotch Whisky
• Cask Type: White oak casks (likely ex-bourbon)
• Price: Approximately £18.49
• Awards: 3 Stars at the Great Taste Awards, demonstrating exceptional quality

The Value Proposition

What’s most impressive about Glen Marnoch Islay is how it captures authentic Islay character at less than half the price of established distillery brands. While it doesn’t reach the complexity of something like Ardbeg or Laphroaig, it delivers a genuine peated experience that satisfies both newcomers and seasoned whisky drinkers.

This bottle proves that quality Islay whisky doesn’t need to break the bank. For under £20, you’re getting a legitimate, award-winning single malt that maintains integrity and regional character.

Ideal Drinking Experience

Glen Marnoch Islay is versatile enough to enjoy neat, but I’d add a few drops of water, which opens up more of those nutty, sweet notes while softening the smoke slightly.

It makes an excellent introduction to peated whisky for newcomers curious about Islay malts but hesitant to invest in pricier options. For experienced drinkers, it’s a reliable everyday dram when you crave smoke without reaching for your special occasion bottles.

Perfect for cool autumn evenings or alongside a cheese board featuring smoked cheddar or blue cheese.
