The NV Extra Brut Blanc de Blancs Longitude 1er Cru comes across as a bit closed and narrow today. I would give it 6-12 months in bottle to come together. Citrus, dried flowers, mint, spice and marzipan all open in the glass. The Longitude is powerful, but also inward. This release is 60% 2018 and 40% a perpetual reserve that goes back to 2004. Dosage is 4 grams per liter. Drinking window: 2021 - 2029, (VM, 92 points).
