I’m a huge fan of the Blanc de Blancs style and the Charles Heidsieck was a particular favorite of mine with its pristine, polished fruit flavors, floral aromas and brilliant acidity.  Great minerality adorned with the addition of 25% reserve wine. ***+(FR)
Frank liked this more than me.  While I enjoyed its fresh acidity and immediate complexity, it finished with a touch of bitter phenolics that I found a little off-putting.  My guess is it will improve in the cellar. **?(JR)
