Bit confused by this wine – some sips I liked more than others…

Piccini Chianti Classico Riserva 2009, Tuscany, Italy (£11.49 Morrisons)
Plus points: I really like the supple woody cherry flavour, notes of herbs and tea, and the light edge of volatility that lifts the flavours rather than murders them, and adds in a note of old school desk varnish character.
Minus point: there’s a green bitterness lurking in the background, maybe from poorly seasoned oak. Hmmm… B+
