The wine from full bottles and Mags is cuvée 181, 67% 2015, deg. 9/2018 (bottles) and 1/2019 (Mags); it’s a little grassy but acceptably so, and the mag is more mineral and craggy, not surprisingly. It’s actually the better rendition, though don’t take that to mean it’s ready to drink immediately. I’m actually kind of sad about restaurants who pour young Champagne from Mag; it looks good but often the wine’s stiff and unyielding. One final note: when Gimonnet says a reserve wine is (let’s say) 9.3% 2014, what that means is it is the entire NV blend of 2014, so that all the reserve wines THEMSELVES contain reserve wines. Moreover, these wines are stored in MAGNUM, not in tank, which gives them greater freshness and refinement.
