Thanks for all the replies, lots to sample.
Giles, I like the local connection and recommendation. After finishing Uni I worked on farms around East Malling, and remember drinking in a pub not far away where the owner contended that the famous Kent Golding had first been commercially grown in a hopgarden adjoining his land.
Graham, the Greene King one sounds like a good introduction for someone unused to drinking.
Dave - good call on the Gewürztraminer, this used to be a favourite. A lot more new world ones around nowadays that I haven't tried.
