Single-vineyard CPC sparkling wines come from many soils (sandy granite, slate, calcareous, clay, loam) and microclimates. Xarel.lo is the most preferred variety but may be blended with Macabeo and/or Parellada. Chardonnay and Pinot Noir are also used. Most age their wines for much longer than 36 months minimum age. Vines must be at least 10 years old, with lower yields.
