Saint Joseph Blanc is a serious and excellent wine, with weight and complexity but not so imposing as Hermitage Blanc. It is arguably better than the red at the same price. The "Lieu Dit Saint Joseph," from one of the very finest vineyards in the appellation, is deeper and richer, with the added complexity gained by 6 months aging in 2nd year barrels. It drinks well young, but should age and improve for several years beyond the vintage.
Blend: 93% Marsanne, 7% Roussanne
"Even better and one thrilling white, the 2012 Saint Joseph Lieu-Dit Blanc, which comes from the vineyard that gave the appellation its name, is a smoking blend of 93% Marsanne and 7% Roussanne that’s brought up all in new oak barrels. Rich, textured and full-bodied, it oozes notions of caramelized peaches, toast, cream and brioche. It’s knockout stuff and should drink nicely for over a decade (although I’d drink it over the coming couple of years). "
The Wine Advocate
"Bright yellow. Fresh peach, lemon pith, smoky oak and honeysuckle on the highly perfumed nose, with an iodine nuance building in the glass. Firm and youthfully taut, in a distinctly steely style but showing seriously concentrated pit and orchard fruit character. Finishes spicy, stony and very long, with excellent clarity and resonating minerality."
