Bilberry
Vaccinium myrtillus · Ericaceae · also known as Whortleberry, Whinberry, Blaeberry, European blueberry
Europe's small, dark wild blueberry — more intense and tart than the cultivated kind, and stained purple all the way through. A laborious hand-picked forage fruit famous for eye-health folklore and deep-purple pies.

British WWII propaganda claimed RAF night-fighter pilots ate bilberry jam to sharpen their vision in the dark — a story invented partly to hide radar, but one that gave the humble bilberry a lasting reputation as an eye tonic.

How to select & store
Picking a ripe one
Foraged from moorland and forest floors — choose plump, deep blue-black berries; the flesh should be purple inside, unlike a blueberry's pale flesh. Picking is slow work with a berry rake or by hand.
Storing it
A day or two fresh; they freeze and dry well and are widely sold as juice, jam, and dried fruit since fresh bilberries rarely reach shops.
Practical uses
🍽️ Culinary
- Bilberry pie and tart (Sweden's blåbärspaj, France's tarte aux myrtilles)

🌿 Health & traditional
- A famous traditional eye tonic; bilberry extract is widely studied for vision, circulation, and blood sugar
- High-anthocyanin fruit used across European folk medicine
🎎 Cultural
- A cornerstone of Nordic and Alpine foraging, gathered by the bucketful each summer with berry rakes
- WWII RAF pilots were rumored to eat bilberry jam to sharpen night vision — a myth that made the fruit famous
Eating bilberry: what to know
What regular consumption looks like
Bilberry is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of fibre (about 3 g per 100 g), which supports digestion and satiety. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Bilberry contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The bilberry is Europe’s answer to the huckleberry: a small, wild, un-farmed relative of the blueberry, more intense and tart, and — the key difference — stained deep purple all the way through, where a blueberry’s flesh is pale. Bite one and your fingers, teeth, and any nearby pastry go inky.
Hand-picked and legendary
Bilberries grow low on moorland and forest floors, and gathering them is slow, back-bending work with a berry rake — which is why they rarely reach shops fresh and mostly appear as jam, juice, and dried fruit. The reward is flavor and chemistry: an anthocyanin content far above cultivated blueberries, colored throughout rather than just in the skin, and long studied for eye health, circulation, and blood sugar. That eye-tonic reputation got a famous boost in WWII, when British propaganda claimed RAF pilots ate bilberry jam to sharpen their night vision — a cover story for radar that gave the little berry lasting fame. From Sweden’s blåbärspaj to France’s tarte aux myrtilles, it remains a treasured summer forage across the continent.
