02/19/2025 / By Zoey Sky

Bilberries (wild blueberries) are small, deep indigo berries that grow on low shrubs.
Known for their flavor which is a balanced mix of sweet and tart, bilberries offer a more intense taste compared to cultivated blueberries.
Historically foraged and consumed for thousands of years, bilberries are native to Europe, Asia and North America.
Bilberries are rich in bioactive compounds, most notably anthocyanins, which are powerful antioxidants that neutralize free radicals and reduce oxidative stress. The nutrients in bilberries support digestive health, cardiovascular health, bone health and immune function.
Bilberries are the perfect ingredient for salads, smoothies and jams.

Bilberries (Vaccinium myrtillus L.), often referred to as wild blueberries, are a small but mighty fruit that has captivated health enthusiasts, chefs and herbalists for centuries.

Known by various names across cultures — such as European blueberries, whortleberries, huckleberries or blaeberries —bilberries are a close relative of cultivated blueberries but boast a unique flavor and nutrition profile as well as medicinal properties.

Bilberries, with their round shape and slightly tart, sweet taste, are not only a culinary delight but also a nutrient powerhouse packed with phytonutrients that can support overall health.

The bilberry: A closer look

Bilberries are round, about five to nine millimeters in diameter, and grow on low shrubs. They are easily recognizable by their deep indigo hue, which comes from powerful antioxidant pigments called anthocyanins.

When ripe, the skin of bilberries is smooth and slightly waxy, encasing a juicy, dark purple flesh that can stain fingers and tongues alike.

The flavor of bilberries is a delightful balance of sweet and tart, with a more intense and complex taste compared to cultivated blueberries. Their rich, earthy undertones make them a versatile ingredient in both sweet and savory dishes.

Historical and cultural significance

Bilberries have a rich history that dates back to ancient times. Native to Europe, Asia and North America, these berries have been foraged and consumed for thousands of years.

Historical records suggest that bilberries were used by the ancient Greeks and Romans for their medicinal properties, particularly for digestive and vision-related ailments.

During World War II, British Royal Air Force pilots reportedly consumed bilberry jam to improve their night vision, a testament to the fruit’s long-standing reputation as a vision-enhancing food.

Today, bilberries are primarily found in the wild, thriving in acidic, nutrient-poor soils in temperate and subarctic regions. They are especially abundant in Scandinavian countries, the British Isles and parts of Eastern Europe.

Unlike their cultivated blueberry cousins, bilberries are smaller, darker and more intensely flavored.

Nutritional composition and phytonutrients

Bilberries are celebrated for their exceptional concentration of bioactive compounds, particularly anthocyanins, which are responsible for their vibrant color and many health benefits.

These phytonutrients are potent antioxidants that help neutralize free radicals, reducing oxidative stress and inflammation in the body. (Related: The jackfruit: A superfood source of vitamin C, fiber and other nutrients.)

In addition to anthocyanins, bilberries contain:

Fiber – Promotes digestive health and satiety
Flavonoids – Flavonoids such as quercetin and catechins support cardiovascular health
Manganese – A trace mineral crucial for bone health and metabolism
Phenolic acids – Includes chlorogenic acid, which is known for its anti-inflammatory and blood sugar-regulating properties
Vitamin C – An essential nutrient for immune function and skin health

Health benefits and potential therapeutic uses

The nutrient-dense profile of bilberries makes them a valuable ally in preventing and managing a variety of health conditions.

Research has highlighted several key areas where bilberries may offer significant benefits:
