What would be the best description of 'insipid' coffee?

The term 'insipid' is commonly used to describe something that lacks flavor, zest, or interest. In the context of coffee, describing it as 'insipid' indicates that it is dull and unexciting in taste, failing to provide the rich, bold, or invigorating qualities that one might expect from a well-brewed beverage. This aligns perfectly with the notion of being 'boring and lacking flavor,' making it the most fitting description among the choices provided. The other options suggest qualities that would be the opposite of 'insipid,' emphasizing richness, strength, and robustness, which do not reflect the meaning of the word.
