What is the percentage of alcohol in a glass wine?

There is no single answer to this question because the alcohol content of wine can vary greatly depending on several factors:

* Type of wine: Red wines generally have a higher alcohol content than white wines.

* Grape variety: Some grape varieties naturally produce wines with higher alcohol content than others.

* Winemaking techniques: Winemakers can manipulate the alcohol content through techniques like adding sugar or allowing the grapes to ferment for longer periods.

* Region: Wines from different regions can have varying alcohol levels due to differences in climate and soil.

Here are some general guidelines:

* Red wine: Typically ranges from 12-15% alcohol by volume (ABV). Some red wines, like fortified wines (e.g., Port) can have much higher ABV.

* White wine: Usually has a lower alcohol content, around 10-14% ABV.

* Rosé wine: Similar to white wine, typically 10-13% ABV.

* Sparkling wine: Typically has a lower alcohol content than still wines, ranging from 11-13% ABV.

To know the exact alcohol content of a specific glass of wine, you would need to check the label.
