Haevesting of sloe fruits
Though sloe fruits contain about 10 per cent sugar, but still they taste quite due to high acid content. These are astringent too. So sloe fruits are not very palatable for taking fresh. These are, however, used in making jams and jellies.
Sloe fruits are used to make sloe gin in rural Britain. Though sloe gin is not a true gin but an infusion of vodka, gin, or neutral spirits with the fruit to produce a liqueur. A popular liqueur called patxaran is made with sloes in Spain. Wine made from fermented sloes is considered a delicacy in Germany and other central European countries. Sloes are also preserved in vinegar and are similar in taste to Japanese umeboshi.
The juice of the berries is also used for dying lines.
Gin made from sloe fruits
The fruits are also dried for off season use.
Sloe fruits are high in mineral content, especially potassium.
Shrubs of sloe are mostly planted as protective hedge and these are very suitable for this purpose because of the presence of thorns.
New plants can be raised from seed but it is very slow. The seeds may take upto 18 months to germinate. Propagation is aso possible from softwood cuttings and air layering.
Slow favours sunny locations.
