The Richest Yolks
You Say?

You heard that right - we top the yolk scale. And yes, there is such a thing called a Yolk Scale! Much like the Richter Scale measures the strength of an earthquake, the Yolk Scale measures the colour and richness of an egg's yolk. That golden egg yolk colour you see in every St. Ewe box? It's not by accident. We are so proud that our Rich Yolk eggs top the scale with their deeply golden yolks - the mark of quality, care, and British high-welfare free-range hens living their best lives.

St. Ewe Rich Yolk eggs are amazing to use in the kitchen because of the incredible vibrancy in the colour of the yolks, giving that natural, amazing golden hue when used - and they are delicious!

Why The Colour Of The Yolk Makes All the Difference in the Kitchen

A golden yolk isn't just beautiful to look at - it changes what your cooking can do. That deep, rich colour signals a higher concentration of carotenoids, which means more flavour, more vibrancy, and a more luxurious result on the plate.

When a recipe calls for eggs, it's the yolk doing the heavy lifting - and the richer the yolk, the richer the result. Hollandaise takes on a gorgeous golden colour. Homemade pasta becomes a deep, burnished yellow rather than pale and flat. Even a simple fried egg, with its rich, vibrant yolk gleaming against the white, feels like something worth sitting down for. That's why chefs reach for St. Ewe Rich Yolk eggs when the colour and quality of their dish matters.

Have a Question?

For optimum freshness, keep eggs refrigerated at a constant temperature below 20°C and always store them in their original box - egg shells are porous (around 7,000 pores per egg!), so they can easily take on the smell or taste of surrounding foods. Nobody wants an egg that tastes like an onion. If you do remove them from the box, use them in date order, and always discard any dirty, cracked, or broken eggs.


You would be hard-pressed to find a food that contains such an ideal mixture of nutrients as eggs, as they are one of nature’s superfoods, fitting into many diets and lifestyles. Along with high-quality protein, eggs are naturally rich in vitamin D, B2 (riboflavin), B12, iodine, and selenium, and contain several other essential vitamins and minerals.

You can check egg freshness by placing the egg in a glass or bowl of water. Fresh eggs will sink and lie flat on the bottom, while older eggs will stand upright or float. Additionally, St. Ewe eggs carry a date stamp for guidance.

St. Ewe Free Range Eggs are known for producing eggs with rich, golden yolks and a full, delicious flavour. Our Rich Yolk eggs are a favourite with chefs and home cooks who want standout, golden egg yolks for everything from vibrant brunches to rich pasta dough and sauces.

In the UK, there isn’t a specific certification as such that guarantees a “rich yolk”. However, much like the Richter Scale measures the strength of an earthquake, the Yolk Scale (Roche Scale) measures the colour and richness of an egg's yolk. St. Ewe Rich Yolk eggs top the scale with their delicious, quality yolks from British high-welfare free-range hens.

An egg yolk's vibrant golden colour comes mainly from a hen's diet. When hens eat plants and grains rich in carotenoids (natural pigments found in things like leafy greens, maize, marigold and peppers), those pigments are passed into the yolk, deepening it from pale yellow all the way to that rich, golden hue that St. Ewe Rich Yolk eggs are known for.

Golden yolk eggs aren't just visually striking - that deeper colour reflects a diet richer in carotenoids, which are natural antioxidants. While the overall nutritional profile of an egg doesn't change dramatically based on yolk colour alone, hens producing deeply golden yolks are typically better fed and better kept - and that quality shows with every egg cracked.
