From my bedroom window I can see the Nyetimber vineyards and have to agree, it is very special, the Classic Cuvee is brilliant. I think there’s a chance of finding it in Waitrose, possibly also in duty free HT ?
Quaff (Fiveways and Portland Road, Hove) will certainly sort you out, there are more imaginative and better choices than Ridgeview IMO. How you going to get it back in hand luggage?
