Explanation:

- Admirer: Someone who has a particular amount of respect or esteem for something or someone, but not necessarily with expertise or deep knowledge.

- Connoisseur: A person who is especially competent to pass critical judgments in an art, particularly one of the fine arts, or in matters of taste, often related to food, drink, etc. This is the correct term for someone who knows a lot about and enjoys the arts, food, or drink.

- Ascetic: A person who practices severe self-discipline and abstention from all forms of indulgence, typically for religious reasons. This does not align with enjoyment or expertise in arts or fine living.
