NV Jacques Selosse Substance Blanc de Blancs Brut Champagne Grand Cru from this lot has the following scores - The Wine Advocate 100 points. This is the tasting note for NV Jacques Selosse Substance Blanc de Blancs Brut Champagne Grand Cru from Robert Parker - with a score of 99 points. One of the pinnacles of the tasting with Selosse, unsurprisingly, is the NV Blanc de Blancs Grand Cru Substance, a wine with the most complex making, going through four stages of maturation - from barrels to the bottle. As always, it derives from a solera created in 1986. Originally, the wine was sourced from two parcels in Avize, but today the base wine (which eventually contributes only about 4.8% to the final blend in the bottle) is produced from a selection of plots in the village. Guillaume opted to include parcels that best fit the desired balance—sometimes these will be south-facing, other times east or even north-facing sites. Muscular and multidimensional, it jumps from the glass with a bouquet of kaleidoscopic complexity, featuring notes of orange zest, spices, beeswax, toasted hazelnuts and dried fig. On the palate, it is full-bodied, vinous and textural yet searingly chalky—even more mineral than Les Chantereines. Guillaume Selosse remarks that oxidation during maturation (and through multiple transfers between different vessels) frees the wine from fruit in a classic sense, leaving mostly chalky extract and enhancing its mineral aspect. Every time I taste at this great domaine, I vacillate between Substance and the lieux-dits as to which wine best defines this benchmark producer. The latest release was disgorged in July 2024 with 1.5 grams per liter dosage and promises a concentrated, unforgettable drinking experience.
