Carlos I Single Malt Whisky is a Spanish whisky made with 100% Spanish barley and presented in a 70 cl format. Its process combines double distillation with maturation in Carlos I Solera Gran Reserva casks and a subsequent finishing in historic VORS casks of Amontillado and Oloroso from Osborne. The casks used distinguish the stages of production: the Carlos I Solera Gran Reserva casks take part in maturation, while the historic VORS casks are used for the later finishing. This sequence reinforces a personality deeply linked to the Jerez tradition, one of the highlighted traits in the product description. Its presentation therefore brings together three central elements: the single malt identity, the Spanish origin of the barley and the double distillation, along with a maturation and finishing process marked by Carlos I and Osborne casks.
