While I havent actually tried the port (i hope the receiver of the gift cracks it open :) ), the customer service was nothing short of excellent. I stupidly clicked the standard delivery option instead of express, and tried the cancell the order. Instead the company- Vintage Wines and Ports, offered to dispatch expressly f.o.c.
I couldnt have asked for more. It arrived the next working day, in perfect condition, with a very nice leaflet explaining what sort of year 1984 was in terms of harvest/vintage etc.
