This comes from all three communes where Lilbert farms vines. Typically it is made with three consecutive vintages and is aged on its lees for a minimum of three years. With the warmer years, Bertrand began to lower his dosages from the usual 6-7 grams to less than 5 grams, beginning with the NV based on 2014. 

The NV based on 2015 received 4 grams; the NV based on 2016 received 3 grams. The style isn't changing so much as the weather is warming. Annual production is 1,650/12-pk cases plus 2,000 half bottles.
