In this 2026 supermarket Irish butter taste test, we blind-tasted eight popular brands available in major Irish stores. From the iconic Kerrygold to budget supermarket options like Aldi’s Kilkeely and Lidl’s Dairy Manor, we evaluated texture, taste, colour, and value.
All butters are made from Irish (or Irish/Northern Irish) grass-fed milk with at least 80% fat content.
Butter is simple: cream and salt. Yet subtle differences in milk quality, season, and production create noticeable variations. Our panel found all tested butters delicious, with minimal flavour gaps among creamery brands. However, standout winners emerged in creaminess, colour, and overall preference.
Why Irish Grass-Fed Butter Stands Out Globally
Ireland’s temperate climate and grass-based farming produce milk rich in beta-carotene, giving butter its signature deep yellow hue. This natural colour, along with higher omega-3s and CLA, sets Irish butter apart from grain-fed counterparts. Kerrygold has long capitalised on this, becoming a global icon, but supermarket own-brands now offer comparable quality at lower prices.
Serving sizes vary: café pats are ~7g, while packet labels use 5g or 10g (≈75 calories). We focused on spreadability, flavour on toast, and versatility for baking/cooking.
Best Overall: Glenstal Traditional Irish Butter ★★★★★
Widely available | 454g, Tesco €4.99 (€10.99/kg)
Made with summer milk from grass-fed cows in Co Limerick, Glenstal boasts a rich golden colour and exceptionally creamy texture. It’s naturally softer than winter-milk butters, spreading effortlessly. Our tasters consistently preferred it to Kerrygold at the same price point, praising its luxurious mouthfeel and balanced flavour.
Glenstal Traditional Irish Butter – the top-rated choice in our 2026 taste test, with its rich yellow hue and creamy texture.
Best Budget Options
M&S Food Salted Irish Butter ★★★★
Marks & Spencer | 454g, €3.40 (€7.48/kg)
Produced by North Cork Co-operative Creameries in Kanturk, Co Cork. This pleasant, creamy butter delivers excellent value in M&S’s price-matching strategy. Made from Irish grass-fed milk, it offers smooth spreadability and clean taste.
M&S Food Salted Irish Butter – a strong budget contender with creamy consistency.
SuperValu Irish Creamery Butter ★★★★
SuperValu | 454g, €3.39 (€7.47/kg)
Also from North Cork Creameries (same as M&S). This Great Taste two-star winner (2022) has a slightly yellower hue and pleasant, creamy profile. Hard to distinguish from premium brands, it’s a reliable everyday choice.
SuperValu Irish Creamery Butter – award-winning and great value.
Best Splurge: Simply Better Abernethy Sea Salted Butter ★★★★★
Dunnes Stores | 125g, €2.99 (€23.92/kg)
Hand-rolled in small batches with traditional paddles and Irish Atlantic sea salt. This artisan-style butter from Northern Ireland has delicate flavour and luxurious texture. Ideal for special occasions or small households.
Simply Better Abernethy Sea Salted Butter – the premium indulgence pick.
The Rest: Solid Performers
Kerrygold Irish Creamery Butter ★★★★
Widely available | 454g, Dunnes Stores €4.99 (€10.99/kg)
Produced in Cork from grass-fed milk. The global benchmark, famously called “the butteriest butter” by The New York Times. Delicious, but testers found it hard to justify the premium price over similar supermarket options.
Kerrygold Irish Creamery Butter – iconic but no clear winner in blind test.
Dairy Manor Irish Creamery Butter ★★★★
Lidl | 454g, €3.39 (€7.47/kg)
Made by Lakeland Dairies (Cavan) using Irish/Northern Irish milk. Pale but perfectly acceptable, with good spreadability. Excellent for heavy users seeking value.
Dairy Manor Irish Creamery Butter – reliable and budget-friendly from Lidl.
Kilkeely Creamery Butter ★★★★
Aldi | 454g, €3.39 (€7.47/kg)
Produced by Tirlán at Ballyragget, Co Kilkenny. Pale, pleasant, and virtually identical to other creamery butters. Perfect for Aldi loyalists.
Kilkeely Creamery Butter – Aldi’s dependable everyday Irish butter.
Tesco Irish Creamery Butter ★★★★
Tesco | 454g, €3.39 (€7.47/kg)
Also from Tirlán (same as Kilkeely). Silver Award winner at Blas na hÉireann 2021. Solid, good-quality butter with no flaws.
Tesco Irish Creamery Butter – award-winning and widely accessible.
Key Takeaways from the 2026 Irish Butter Taste Test
Supermarket own-brands have closed the gap on Kerrygold. Glenstal stood out for its summer-milk richness, while budget options from M&S, SuperValu, Aldi, Lidl, and Tesco delivered excellent quality at €3.39–€3.40 per 454g. Abernethy offers artisan luxury for special moments.
Whether you’re spreading on soda bread, baking scones, or cooking, Irish grass-fed butter remains a kitchen staple. In 2026, you don’t need to pay premium prices for premium taste—supermarket shelves are stocked with winners.
