This is a wine with staggering length and immense purity. It's as powerful as chardonnay can be, showcasing an incredible depth of pure fresh lemons, yellow grapefruit, honey and dried white and yellow flowers. The concentration and complexity of primary fruits are outstanding, and there are some more exotic flavors here too in the peach and green-mango spectrum. The texture is ultra-fine and creamy through the mid-palate, its majestic curves sweeping long around a sturdy mineral core. This is very silky and focused, offering gently creamy moments before twisting towards a composed, restricted and compressed chalk-like finish. It delivers an impression of chardonnay that captures incredible richness, fleshiness, persistence and power. Yet the acidity is staggering while being simultaneously perfectly balanced. Drink now but this will have a lot more to come after 2020.

Pure Chardonnay from the walled vineyard in the heart of Le Mesnil, this intense wine from a great vintage is tight and mineral, still showing hints of toast from its barrel fermentation. With its taut texture, complex acidity and crisp citrus, it's very young, but will age indefinitely. Showing the beauty of Chardonnay in Champagne at its best, it will certainly still be impressive come 2030.

98+ Krug's beautifully citrus colored 2002 Blanc de Blancs Brut Clos du Mesnil (ID 415068 - disgorged IV/2015) shows a deep, complex, very clear and precise if not etherial bouquet with citrus aromas intertwined with chalk and noble brioche notes in the background. Pure, profound and vibrantly fresh on the palate, this is a straight, athletic, very intense and expressive yet highly elegant and finessed Clos du Mesnil with a unique fresh fruit character! The 2002 reveals a great mineral structure and chalky texture on the palate. The highly complex, energetic finish reveals bracing freshness and vitality as well as the charm and creaminess from the vinification in barrels and possibly the dosage wine that seems to boost the Krug style. While terroir wine is the result of hands-off winemaking, Krug's Clos du Mesnil is perhaps a very particular Krug Champagne—it has great quality, style and complexity that is the result of the winemaking and the addition of the dosage wine. How the Clos du Mesnil would taste if farmed biodynamically, picked later and dosed with nothing but itself is a pointless question, but it hasn't left my mind since I tasted the paradoxical 2002, which is terribly fresh on one hand and also has this unique Krug reserve style. Notabene: This doesn't include the hypothesis that the wine could be any better. It would just be different and surely less "Krug," which is not what we really want, do we?

The most extreme of the four Krug wines our panel tasted for this issue, the single-vineyard Clos de Mesnil presents chardonnay at its most severe. In fact, the flinty reduction put off some of our tasters. (I had the opposite reaction, scribbling, “Wow, smells like roast veal in heaven.”) The wine’s acidity proves to be elastic, starting out narrow and powerfully chalky before stretching to encompass all the richness the wine reveals as it opens with air. The structure tightens around luscious lemon-curd flavors with its youthfully green lime-zest chardonnay grip. By definition this is less complete than the 2002 Krug (above); on the other hand, it is more distinct, demonstrating the depth and detail one variety and one parcel of vines can achieve in an extraordinary vintage.

A lovely, lacy Champagne, with ripe apricot, fennel seed and espresso aromas. This caresses the palate with a finely detailed mousse and expansive flavors of pineapple pâte de fruit, toasted brioche, fleur de sel and grated ginger. Long and chalky on the finish, this is a prima ballerina, showing power cloaked in grace. Disgorged winter 2015. Drink now through 2032. –AN
