Across the Nelson and Marlborough region there are number of wineries that are renowned for producing outstanding Pinot Noir wines, however, in a recent report by Nick Stock regional stars include Neudorf, which works with old vines, and Mahana, run by Michael Glover.
Stock described both the 2014 and 2015 Neudorf Moutere Pinot Noirs as worthy of collecting and maturing; capable of attaining the kind of sweet decay that you find in the best older Burgundy wines with age.
