Spreading the love of our tasty
butter to every UK household
We think Wales is the best place in the world to make butter! In years gone by, butter was churned on most farms across the land and there is a strong Welsh connection with salty butter. The historically heavily salted butter recipes were a key part of Welsh Miners’ diets to help them maintain their salt levels as they worked hard underground in the mines.
This tradition for salty butters still lives on today. We have retained our unique Welsh recipe which is crafted to deliver just the right balance of salty notes for modern tastes, whilst honouring our connections with the past.
We want to delight our customers with great tasting and convenient products which don’t compromise their natural, healthy status.
Churned in Caerphilly since 1966
Here at Castle Dairies, we take our many years of expertise in great-tasting butter making and butter churning seriously. We know what we are doing – we are passionate about getting it right.
Some of our team have been with us for over 40 years – true butter experts who know their craft inside and out. We have combined their knowledge with the latest technology, investing over £1m in the UK’s most modern churning facility. And the result – award wining and delicious tasting butter with just the right salty notes.
We make our spreadable butters using a simple, gentle cold mix process – with no added heat. It is important to us to keep it simple, so the butter stays as pure and tasty as possible. We don’t overwork the butter so the delicate butter fats stay intact and we believe this gives a better and richer tasting product. To make spreading effortless, we blend our butter with just the right amount of rapeseed oil to soften the texture, so it’s ready to enjoy straight from the fridge.
As we look to celebrate 60 years of butter making in 2026, we are proud of our heritage and the great tasting premium butters behind our brand.
But we are not stuck in the past. Innovation inspires us. We look forward to continuing to perfect our craft and bringing fresh ideas to the butter aisle – we are just getting started!
Collaborating with
like-minded brands
Our strong collaboration with Halen Môn Sea Salt began in 2018 – a perfect fit with a family based, like-minded, artisan Welsh food manufacturer.
Halen Môn was founded in 1997 by Alison & David and has expanded to include their 3 children. As they left a pan of seawater to boil on the Aga at home, they watched salt crystals start to form and they knew they’d struck culinary gold!
They make salt the long, proper way – with no shortcuts! That’s why Halen Môn Sea Salt is famous across the world. They care deeply about the environment and they have received the Queen’s award for Sustainability and recently become B-Corp registered.
They are a perfect partner for us at Castle Dairies, with both companies winning Great Taste awards for our high quality products. Their crunchy delicious sea salt packs a punch in our butters giving them just the right amount of crunch and deliciously salty notes.
We hope you enjoy them as much as we do!
