From a single, sixty-year-old vineyard named Piedra Juan situated on sandy, volcanic soils in the municipality of La Frontera, John Stone is a steep site with dramatic views of the crescent-shaped El Golfo. Planted with Vijariego Blanco (better known in the Canaries as Diego) and Listán Blanco, this site bears the full brunt of the nearly constant trade winds. This site is harvested by hand, fermentation begins by natural yeasts in tank and finishes in French oak barrels leaving a small space at the top for the development of a thin layer of flor.
92 points, "The white blend 2019 John Stone is a blend of Verijadiego Blanco and Listán Blanco from a single vineyard called Piedra Juan (literally, John Stone, or Stone John...) planted over 60 years ago on sandy soils in the higher part of Frontera. Halfway through fermentation, it was transferred to barrel, where it completed fermentation and matured until June without racking; during that time in barrel, it developed a veil of flor yeasts. It has a tender personality, reminiscent of some of the young ouillé whites from Jura but not really marked by the flor, which is very subtle, with notes of fennel and herbs. The wine has higher acidity and a touch of salinity. This should develop nicely in bottle, and with the acidity it has, it should be long lived. Only one 300-liter barrel was produced, 370 bottles. It was filled in July 2020." - Wine Advocate
