* Amontillado is a specific type of dry sherry wine.
* Antonyms are words with opposite meanings.
Therefore, you can't really have an antonym for a specific type of wine. However, you could consider these as potential opposites in different contexts:
* Sweet wine: If considering the "dry" characteristic of Amontillado, the opposite would be a sweet wine.
* Another type of wine: If considering the "Amontillado" part, you could say other types of sherry or other wines entirely.
It's important to understand the context in which you're looking for an antonym to provide a better answer.
