I've always enjoyed the Reserve, which I believe is made from a selection of favorite barrels. Clones represented are Dijon 667, 115 and Pommard 4 grown on legendary Goldridge sandy loam soils.
From a historical perspective, the 2009 vintage Kanzler Reserve has always showed very well, comparing favorably even with red Burgundy from Côtes de Beaune.

This 2014 bottling showed quite young and tight upon opening. Decanted to get some air which loosened it up a bit after a couple of hours and let the fruit show thru. And oh what fruit! Savory dusty cherry up front with a tart pomegranate finish. Nothing is out of place in this supremely balanced example of top notch Sonoma Coast pinot noir. Right now, it's a wine of beautiful potential.
I'd give this at least another five years to approach optimal drinking window. It seems to have plenty of structure to easily age another 20 years.
