"The Romaee-Conti of Jerez".
Moscatel Toneles is one of the legendary wines of the sherry region, produced by Valdespino.
It is an extremely old, powerful Moscatel that was long forgotten, because there was simply no market for it - up until Robert Parker gave it 100/100 a while back. Anyway it is said to be over 100 years of age (though they don't seem to disclose that).

"The NV Moscatel Toneles has reached a mythical status locally in Spain. It's an extremely old, concentrated and powerful sweet wine that was long forgotten, because there was no market for it. The color is dark brown, almost opaque with amber-green edges. The ever-changing nose is an explosion of spices (curry and cinnamon) and noble woods, and from the sheer concentration it displays a myriad of roasted coffee, dark chocolate, balsamic herbs and even a note of coconut. After some time in the glass the roasted orange notes of Muscat come back intermixed with very spicy incense notes. Give it more time and it smells of camphor. It's fascinating to smell it over the course of a few hours - even days. The palate is immensely concentrated, with the alcohol perfectly integrated and the extreme sweetness compensated by a piercing acidity that reminds me of some century-old Madeiras. It ends with an acute coffee note. The aftertaste is eternal. It is exceptional that such an old wine (it could be over 80 years of average age) keeps the freshness and balance, but when this happens, the wine is exceptional. A world-class sweet wine that shows what aged Muscat is able for. With its 430 grams of residual sugar, this wine is indestructible, but only 100 bottles are withdrawn and bottled yearly from a single, large cask.

I've often called Valdespino "the Romanee-Conti of Jerez." Well, there, I've said it. To me they represent quality and tradition at the very top of the Sherry hierarchy. The winery, soleras and brands are old, registered in 1875, but with documentation about their commercial and winegrowing activities going back to the 13th century. Their recent history starts in 1999, when Jose Estevez purchases the company from the Valdespino family. Today Valdespino is the jewel in the crown of the Grupo Estevez, which also includes Real Tesoro and La Guita, who stock and age 35,000 botas of Sherry and own 800 hectares of vineyards, 56 of which come from the Pago Macharnudo, on pure white albariza soil, one of the best vineyards in the Marco de Jerez, and 17 hectares from the heart of Macharnudo are still fermented in bota today and form the core of brands like Inocente, Tio Diego, CP or Cardenal. All the wines were carefully and slowly moved to the new facilities of the Grupo Estevez on the outskirts of Jerez, where they continue their development under the supervision of Eduardo Ojeda, technical director, winemaker, who as a wine-lover is very aware of his role preserving these old soleras, wines and traditions." 100/100.
