Nyetimber, Classic Cuvée, brut, 2006
It usually takes some convincing to get continental folk to accept that English sparkling wines are not only drinkable, but can be quite excellent. But since we already know that, we hold them to a higher standard than most other German wine drinkers probably would. It is from this fairly lofty perspective, and only from there, that this one disappointed us somewhat when it was soundly beaten by a French sparkler costing less than half in this mildly humiliating Wine Rambler blind tasting.
That being said, not a bad sparkler by any standard - au contraire (again, see here for details).
