Hedgerow wine kit?

[gilly]

Hi,  i currently have a hedgrow wine kit on the go with plums that i was given, it says after 3 weeks it should have finished fermenting, after 4 and a bit, the water in the airlock still moves along every so often, just really slowly.  Do i just leave it until it stops moving completely or just move on to the next stage?


Thanks.

Gilly.
