My experience from 2016.
Briefly, if you want fresh eating go with Aurora but ideally the even newer varieties (although I have not tasted those yet) (Boreal Blizard, Boreal Beauty, Boreal Beast)
If you want preserves can probably go with any as you will add sugar but the above 4 are still good bets for size and flavor.
So far my yields have been slow to increase so depending on your flavor preference and yard size, I would actually lean towards Titania black currant if I had limited space and wanted jam/syrup.
Haskasp – Tundra (Planted Fall 2013 from prairieplant.com) Survived. No dieback. Tons of flowers.
Haskasp – Aurora (Planted Fall 2014 from Whiffletree) Survived. No dieback. Tons of flowers.
Haskasp – Honeybee (Planted Fall 2013 from prairieplant.com) Survived. No dieback. Tons of flowers.
Haskasp – Borealis (Planted Fall 2013 from prairieplant.com) Survived. No dieback. Tons of flowers.
All the Haskasps were flowering around May 14 with Tundra perhaps a bit later. Aurora and Tundra seem to have the longest bloom time. The plants are still pretty small, about 18-24” tall. The new varieties Boreal Blizzart and Boreal Beauty seem to be amazing with much larger/sweeter fruit and flowering 2-4 weeks later! I just don’t have room!
Fruit was ripening June 15-20 but still tasted pretty sour. I heard leaving them on the bush made a difference so I left them longer. Well the day later the birds discovered them and took about 50%. I netted them quickly but will be sure to do so earlier next year. On July 1st I harvested the rest except for some Aurora’s which were still ripening.
The ones labelled Honey Bee in my photos are actually Borealis. I also had Tundra and Aurora.

Aurora is by far the largest. Tundra and Borealis were similar in size. Taste test with my wife: For fresh eating Aurora won hands down the best. Borealis perhaps had a slight edge over Tundra. Measuring Brix Aurora (17, 14), Tundra (9, 9.8, 11.8), Borealis (12, 12, 11.2) so you can see why Aurora was more pleasant. In the end we ate the Aurora’s fresh and I made a compote with the other 2 by mixing 1 part berries to 0.5 part sugar by weight and it was nice and tasty and acidic.
Yield post bird attack was tiny. Aurora 5 berries (8 grams), Tundra (41 grams), Borealis (32 grams). All are about 3 year old plants.
