I tasted this as part of a "West Coast Wines" themed evening for Sweet Wine Wednesday. I dithered for quite a while between this wine and a Camel Valley Bacchus. I know, I know, I should have gone for the other, seeing as it's located that bit closer to the Atlantic, but on the few occasions I've had Bacchus I've not been particularly impressed.
Knightor are a small outfit located close to the Eden Project and St Austells. The current farm dates to the mid 19th century, but their website says that there are references to the property dating to 1305. (Not particularly relevant if your vines were only planted in 2006, but on the other hand probably quite appealing in a wedding venue.) They say they have 17000 vines, but I can't tell from the tone of their website if this is a way of saying they're really getting big, or that they're really boutique.
Trevannion is a blend of Siegerrebe and Schonberger, two pink skinned varietals. Siegerrebe is a 1929 cross of Madelaine Angevine and Savagnin Rose. It's favoured for cool climates - there's even some grown in Denmark, according to the big book of grapes. Schonberger is another cross, of Pinot Noir and Pirovano I, and in turn Pirovano I is a cross of Chasselas Rose and Muscat of Hamburg. (Is this too much grape breeding information?)
We're told that both varieties were picked when very ripe. They were cool fermented separately in stainless steel, then left on the lees for eight months before blending and bottling.
My initial impression is a very strong aroma memory of some rather rustic vin gris from the middle Loire - a wine which I remember being rather rustic but extremely gluggable.
The nose is fresh and fairly aromatic, with rose petals (or tinned lychees if you prefer), which evolves into a fairly elegant perfume, perhaps something like soap
The palate is strongly aromatic and off dry, with a subtle Muscat or Gewurz-like spiciness. The finish is long and warming, if a little simple.
Over time the wine becomes more floral, but this is probably just me over-chilling it.
Just like that Loire vin gris, this stuff is stupendously gluggable. And well worth the £19 I paid for it. If you see this one, I urge you to buy it. And don't over-chill it.
That vin gris which the Trevannion called to mind was from the valley of Le Loir, a river which flows into La Sarthe, which in turn joins La Loire. The appellation is the (mostly deservedly) obscure Coteaux-du-vendômois. But very gluggable.
