"Wineglass" as a Measurement: Conversion to Fluid Ounces (fl oz) & Milliliters (ml)
The term "wineglass" was historically used as a unit of liquid measure in older recipes, particularly from the 19th and early 20th centuries. Its volume was not strictly standardized but had common approximations.

Important Considerations for "Wineglass" Measurements:
The most commonly accepted modern equivalent for a "wineglass" in old recipes is **2 US fluid ounces (approximately 60 ml or 1/4 cup)**.
However, historical usage could sometimes imply a larger measure, closer to a gill (4 US fluid ounces or about 120 ml / 1/2 cup), especially in British contexts.
Context is key: If a recipe also calls for "teacups" or "gills," it might help determine the relative size intended for the "wineglass."
If the recipe is American and from the mid-to-late 19th century onwards, 2 fl oz is the more likely interpretation.
When encountering this term, consider the other ingredient quantities. If 4 fl oz seems excessive for the recipe, the 2 fl oz measure is probably intended.
Modern wine glasses vary enormously in size and are not used for measurement.
