He is Guillaume Bott who has made wine with Gerard Boudot at Étienne Sauzet and then (and now) at Domaine Simon Bize where he has earned admiration for his excellent work on upgrading the white wines. During harvest he continues at Bize while Tomoko is in daily charge of Chanterives operations.
You can see their hands intertwined on the label shown here. They are currently building their own cuverie in Savigny. I assumed this first vintage was made chez Bize but in fact they rented a cellar in Pommard. (Talking of Savigny, I was actually quite impressed by a Gevrey made by Henri de Villamont recently!)
Flint Wines was showing four of their five wines on Tuesday and they certainly were impressive, whites as well as reds. The Winery of London W9 is currently offering their Meursault 2010, which I have not tasted, here. For value I was particularly taken by the Chanterives 2010 Bourgogne Rouge made, very gently, from fruit grown on the lower reaches of Pommard and the wine has some of the characteristic flavour of that village.
My tasting note: 'Cherry red. Clean, fresh and earthy on the nose. One of those rare wines where "earthy" is not a euphemism for funky; it really does smell of freshly turned earth. Intense cherry fruit too. Lovely pure, simple Burgundian Pinot. VGV 16 Drink 2012-14'
Flint Wines are offering this at £95 a dozen bottles in bond although, needless to say, they have not managed to add this new producer to their website at the time of tasting.
This is clearly a producer to watch. Buy now while stocks and reasonable prices last.
