After a couple of flights with the excellent Taittinger CdC, it seems LH is down to just the Alfred Gratien Cuvee Paradis, which is costing LH all of 40 EUR a bottle
LH say Alfred Gratien was chosen in a blind tasting, for quality.....
Alfred Gratien is produced by Gratien & Mayer who just by coincidence produce the Cremant LH serves in NEK......
The Cremant served in NEK is described in English in the J menu as 'Champagne'
