The small winery of Bimbache, Finca Los Valles, is located in the northeastern part of El Hierro in the municipality of Valverde where it is surrounded by a vineyard planted with Vijariego Blanco (Diego), Listán Blanco, Gual, Babosa Blanco, Forastera Blanca, as well as various other more obscure white varieties. While not as dramatic as the views from Piedra Juan, this site is especially exposed to nearly constant winds being situated on a peninsula only a few kilometers from the ocean. This makes for a taught wine with low pH that is all things volcanic, maritime, and refreshing. Like John Stone, it begins fermentation in tank and is transferred to French oak barrels to finish fermentation.
93+ points, "The vines planted around the winery produced a white 2019 Grand Cruz del Calvario, a multi-grape blend of Verijariego Blanco, Listán Blanco, Forastera Blanca, Gual (Boal), etc., from one of the cooler zones with more influence from the Alisio winds that are associated with higher humidity. The wine is "only" 12.7% alcohol (some wines from 2018 were 14.6%!) and has insane acidity readings, a pH of 2.6 and 10.4 grams of acidity (tartaric). Likes the other single-vineyard white, John Stone, it finished fermenting in a 300-liter oak barrel, where it was kept without racking until bottling. It has a sharp palate and vibrant acidity (Madeira?) and is mineral, stony and saline. This is a pungent, mineral and marine white with crazy readings of acidity and pH. It should live forever. Only 370 bottles were filled in July 2020." - Wine Advocate
