Reviews:

If the 2014 vintage was especially open and demonstrative, the 2015 Cristal is going to require more patience. Unwinding in the glass with aromas of citrus oil, crisp stone fruits, white flowers, crushed mint and subtle hints of buttery pastry, it's medium to full-bodied, deep and layered, with a deep, concentrated and rather introverted core of fruit framed by chalky extract and animated by a pretty pinpoint mousse. This is a serious, vinous Champagne that has considerable substance to age and may well evolve along the lines of the lovely 1985.  William Kelley 95+
