I am fortunate to have been on the Promontory allocation since inception, and am going to share with my wine group. I have a tasting of 2013, 2014, and 2015 vintages of Promontory, Penultimate, and Mascot. I think it will be educational to compare the three wines of same vintage. Just hoping to get some thoughts on how best to structure the tasting: Vertical of each and then discuss? horizontal of the three wines? We usually do blind tastings, but I think given the wines, I am going to reveal what they are in order to give them due respect. Any input would be appreciated! Also, to anyone who has had these: any thoughts on decanting times. I did get some suggestions from the vineyard, but wanted any other input.
