Via the power of suggestion, I had imagined Bollenberg to be an obscure Alsatian grape that had been blended with Pinot Gris - it turns out to be the name of the specific vineyard - and set about attributing the unexpected flavour to this. It has a very deep yellow colour. The palate began with plenty of voluptuous aromatic lychee-type fruit before evolving into an odd - but very pleasant - almost Riesling-like oily dry finish. It would appear I got it from Oddbins and look to have paid around £14 quid but I'd go back for more (if they hadn't gone bust).
I shared it with M & D whose penchant for Gewürztraminer was helpful in their approach (Beccy wouldn't countenance anything as full bodied as this).
