I have had Denbies wines before, namely their Juniper Hill, and have always found them to be very pleasant. The Juniper Hill is a rather aromatic still white wine that is vinted from Bacchus and Schnöburger grapes. Bacchus? Schnöburger? Yes, Bacchus - a Silvaner and Reisling hybrid which is then crossed with Müller-Thurgau. As for the Schönburger...you can look that one up for yourself!
It is heartening to me that there are now some quality wines emanating from the Mother Country, albeit reliant on Teutonic inventiveness, with the introduction of newer, cool-climate hybrids.
All in all, the Rose Hill is a very agreeable mongrel of a wine.
