Naaa, never bothered any of mine whether the winter is warm, cold or
indifferent

Black currants fruit on last years wood so after fruiting you cut out
the old wood and leave in the new.
You say it/they are making a lot of growth, I wonder what fertilizer
you are giving them. It/they might benifit from a low Nitrogen high
potash high phosphate fertilizer to toughen up the growth. With most
fruiting plants, if they are growing to well they don't carry a great
amount of fruit, they have no need to reproduce.
But I would be asking myself if it wasn't time foe a couple of new
bushes.
