Costack started in 2014 with a simple frustration: most UK supermarket seasonings are mostly salt and filler. Real spice content? Sometimes under 30%.
We wanted something different. Real garlic, real paprika, real onion, real spice. Bold blends, built for the way British home cooks actually cook.
Twelve years on, Costack is in UK kitchens across every region. From London to Edinburgh, Bristol to Belfast. Premium spices and seasonings, delivered fast.

A Word From the Founder
Why I Built Costack
I didn't build Costack to be just another spice brand. I built it because I believe food should be bold, cooking should be joyful, and the seasonings that make it happen should be easy to find wherever you are in the UK.
Every order supports a real British business, run by someone who cares about what goes in your kitchen. That's the promise.
I Got Tired of Bland Food. So I Fixed It.
Cooking was never just about eating. It was culture, connection, and creativity. And the one thing that made it extraordinary every time was the right seasoning. The right blend doesn't just season food, it transforms it. That's what Costack is built on.
I launched Costack in 2014 because I saw a gap in the UK market. Premium spice blends that turn a weeknight dinner into something memorable were hard to find without a specialist trip. So I built them. Today, the range is 20 spice blends, every one designed for the way British home cooks actually cook.
Built for Real Kitchens. Trusted by Real Cooks.
Costack is built on a simple belief: great flavour should be accessible, authentic, and unforgettable. Designed for busy families, confident home cooks, and anyone who wants their meals to stand out without complication. No jargon. No specialist knowledge. Just real flavour, every time.
