A good way to start celebrating my 40th, with this late-disgorged 733 alongside a regular 737, to share with my team. Both were definitely in the firm, austere style with plenty of minerality – and this particularly, at 2.5 g/L dosage vs. 3.5 g/L in the 737. Plenty of lees character from the additional ageing sur lie, with some toastiness and subtle lemon. Some saline length, albeit perhaps a little short for a £68 bottle of Champagne. Nice though!
