Chateau Ducluzeau - 2018 - Chateau Ducluzeau - 1.5 L

This one is a magnum: 1.5 litres, two standard bottles' worth in a single vessel. The neck bore matches that of a 750 ml bottle, so the pocket of air under the closure stays about the same size while the wine beneath it doubles, and the cork is cut longer to fit the deeper neck. Ducluzeau's magnum here is the 2018.
