I have always considered Hebrart's old-vine 'Selection' as  arguably the best NV available, often performing better in blind-tastings than some other prestige cuvees. This is the the 'Extra Brut' version, same base wine as the 'Selection' brut but with just 3.5gms/ltr dosage as opposed to 6 gms/ltr in the brut. All Premier and Grand cru fruit with the average vine age of 50 years      

A magnificent entry cuvée that articulates the inimitable talent of Mareuil-sur-Aÿ to magnificently juxtapose the elegance and the presence of pinot noir. For its age, pinot noir predominance and generous reserves, it upholds impressive freshness of Mareuil old-vine lift in precocious red cherry and red berry fruits and waves of anise and fruit mince spice. It concludes with an enticing and seamless fanfare of vibrant morello cherry acidity and wellharmonised dosage. It’s at once succulent and juicy and at the same time lively and fresh, with the pronounced salty chalk minerality of Mareuil tapped as only old vines can do. All hail the great 2013/2012 duo!  94pts Tyson Styelzer 'Champagne Guide 2020-2021'
