Final answer:
Oloroso Sherry is a fortified wine with an alcohol content typically between 18% to 20% ABV, known for its rich and nutty flavors.
Step-by-step explanation:
Oloroso Sherry is a type of fortified wine that comes from the Jerez region of Spain. It is known for its rich and nutty flavors and is darker and more intense than other types of Sherry. Typically, Oloroso Sherry has an alcohol content that ranges between 18% to 20% alcohol by volume (ABV). This higher alcohol percentage is due to the addition of a grape spirit after the fermentation process, which fortifies the wine and increases its alcohol content. Unlike some other types of Sherry, Oloroso is aged oxidatively, giving it a distinctive robust character.
