Blackcurrant tea really is excellent. Blackcurrants are berries that actually grow in small shrubs. In the US, blackcurrants used to be extremely popular. But in the 20th century, growing was banned because they were considered a threat to the logging industry. They have never regained their popularity here. Still, in some parts of the world it remains popular. Dilmah Blackcurrant Tea is one of the last authentic ones left. It has a tart, but still sweet taste. The real berry flavor of blackcurrants is blended with the best black tea to produce a tea with a wonderful aroma.
