btw, I have red and white currants planted and although they produce alot, they really can't touch the flavor of black currants.
My favorite alcoholic drink is probably a Cassis (Black Currant Lambic, which leans on sweet+tart pomegranate-like flavors).
I was pleasantly surprised to see nice frozen ones at my russian supermarket in Philly (Net Cost Market)... and they were AWESOME! That perfect sweet+tart taste (i was surprised they had a tinge of sweet to them).
I just assumed they are bitter since most people just make jam out of them with lots of sugar I assume
and the Ribena type drinks I've tried are ridiculously too sweet with too much sugar added.
If interested here is the frozen currants I got, maybe they have at your location:
I actually ordered these black currant jams on amazon to try them as well:
Hero Black+Red Currant jam
Mrs Bridges Blackcurrant Scottish Preserve
Anyhoo, I actually haven't gotten a good crop from my own plants yet, but I'll be sure to report back when i do (I have a decent amount of varieties growing and they fruit in semi-shade). All i know is the gooseberries and black currants i tried are way better and tastier than red and white currants (although they are very pretty).
Here is my list:
Jonkheer Von Tets
Gloire de Sablons
Pink Champagne currants
Minaj Smyriou (extra one from Whitman Farms)
Hills Kiev Select (rooted one in back area)
