It took the two of us two hours to get most of the currants off four bushes. We ended up with about a gallon currants which steamed down to 2 quarts of juice. Very unsual flavor, by the way. I can't describe it, but think tangy and intense. Maybe a bit woody and grapey. Ish.
I made black currant jelly and entered it in the Weber County Fair with my crab apple jelly and white seedless grape syrup.
