👉 The term "wineglassfuls" is a phrase that refers to a small amount of wine poured into a glass. It's often used in the context of serving wine at a party or gathering, especially when it's not too much for one person to drink all at once. The size of a wineglassful can vary depending on the type and quality of wine being served, but generally speaking, it's considered small compared to a full glass of wine.
