Wine-bibber is a derogatory term used to describe someone who drinks wine excessively. However, there are many other words that can be used to convey this same meaning. Some synonyms for wine-bibber include tippler, drunkard, alcoholic, boozer, lush, sot, and inebriate. Others might include imbiber, wine-lover, or connoisseur, though these words do not necessarily imply that the person drinks too much. It is important to choose your words carefully when talking about someone's drinking habits, as it can be a sensitive subject. Using a more neutral term like "wine drinker" might be more appropriate in some situations.
