Oregon is the leading blackberry producer in the world.
Blackberries are notable for their high nutritional content of dietary fiber, vitamin C, vitamin K, folic acid, and the essential mineral manganese.
Blackberries rank highly among fruits for antioxidant strength, particularly due to their dense contents of polyphenolic compounds. Blackberries have an ORAC value (oxygen radical absorbance capacity) of 5347 per 100 grams, making them among the top-ranked ORAC fruits.
One Celtic legend says that ”when you put blackberries on a threshold or windowsill, you can force a vampire to count over the thorns and berries until morning comes.”
