Wine Cuvee Monsignori White Argyros Estate. Cuvee Monsignori is Estate Argyros’ vision on what Santorini Assyrtiko can actually be. Excessively old Assyrtiko vineyards, at least two hundred years old, giving minute yields. Fermented, partially uninoculated, in stainless steel, at cool temperatures and aged for ten months in stainless steel tanks on fine lees. A wine of breed, extract and length, that needs about four years in bottle to unfold and can be confidently kept for more than a decade after vintage.
