Flavus 2018 is a wine made with grapes from Viña Sastre's oldest vines. These white Cayetana vines, which are not typical of this Denomination of Origin but grow with great success in Viña Sastre, have a very low production. It is the only white wine of the house and revalues historical vines for its exclusivity, in 4,000 bottles, which makes it charming over the years. A product that should be taken into account to know what is exceptional about this winery.
