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.
94+ points, "The vines planted around the winery are the origin for the white 2020 Grand Cruz del Calvario. It's a pungent white with incredible parameters, a wine that Rayco Fernández described as a volcanic lemon. It reminded me of a white from Vatan in Sancerre, but this is 3,000 kilometers south in a subtropical region! This is sharp, clean, young and vibrant, produced with a multi-grape mix of Verijariego Blanco, Listán Blanco, Forastera Blanca, Gual (Boal), etc., with a moderate 12.35% alcohol and insane acidity readings, a pH of 2.68 and 10.3 grams of acidity (tartaric). It finished fermenting in a 300- and a 500-liter oak barrel. Super austere and for the long run. They were able to produce 1,000 bottles that were filled in June 2021. But they lost the crop in 2021." - Wine Advocate
