From older stocks of Colombard, Chenin Blanc, Semillon and Pinot Noir. For Osocalis, the brandies of Colombard from California have fantastic finesse and show the true potential of California Alambic brandies. However unlike the precocious Pinot Noir, Colombard takes decades to show its full potential. Thus, their XO is blended from brandies that have been in barrel for decades. While by old world standards their stocks are still young, the XO shows the rich development of Rancio with hints of orange peel, dried apricots, walnuts, cacao and a rich leatheriness.
