Wild Service tree: Sorbus torminalis

PRODUCT HIGHLIGHTS

The fruits are used to make strong alcoholic drinks and can also be used to flavor alcoholic drinks such as whiskey. In traditional medicine the fruits of the Wild Service Tree have been used for their astringent effects which are due to the high tannin content. Wild service tree represents the most valuable hard wood on European market. Nowadays the wood is mainly used for decorative veneers, but in the past musical instruments, billiard sticks and screws for winepresses are just some of the products made from it.

It’s good to freeze the fruits to make them edible. Therefore it is recommended to harvest fruits after the first frosts, because after freezing they contain less tannin and become pastier.

ID&ECOLOGY

Wild service tree is a deciduous tree, which can reach 25 – 30 m in height. The trunk can reach over 1 m in diameter. Bark is smooth and grey colored. It’s stripping away leaving darker layers beneath. Leaves have five to nine lobes, with both sides smooth and shiny. Flowers flourish during May and June. They are monoecious hermaphrodite and insect pollinated.

The fruits are round to oval, greenish colored, 8-10 mm in diameter; they are ripening in September to November, when the color changes to reddish – brown. The tree can live up to 300 years of age. Wild service tree prefers clay and lime based dry soils. The plant is thermophilic, and the fruits contain high content of pectin, vitamin C, flavonoglycosides, and fruit acids. The optimum mean annual temperature is 10 °C – 17 °C (it withstands down to -5°C in April), precipitation 700 mm – 1500 mm, pH range from 3,5 up to 8. Young trees are susceptible to browsing by ungulates. The leaves can be attacked by leaf scab (Venturia inaequalis (Cooke) G. Winter), leaf aphids and gall mites (Eriophyes spp.). Serious threat for older stems is honey fungus (Armillaria spp.)

MANAGEMENT

The species is growing in small groups or as solitary trees. Since small quantities of wood are harvested and berries are not so popular, management is not developed.

TRADE

There are no data about global berries trade, although small scale trade exists. The berries are sold directly by farmers, on street sales or via restaurants.

They are mostly used as snacks or as ingredients in muesli or chocolate. Other Wild service tree products are: honey, noodles, cakes, etc.

Although it has high quality timber, there is no importance of this species on wood market, since only several thousands of cubic meters are harvested yearly.
