Which lighter wine or water?

It's impossible to say definitively which is lighter, wine or water, without more information. Here's why:

* Density: Water has a density of 1 g/mL, while wine's density varies depending on the type of grape, alcohol content, and sugar levels. Some wines can be denser than water, while others might be slightly lighter.

* Weight: Weight depends on volume. A liter of wine will weigh more than a liter of water because wine is denser. However, a small glass of wine will likely be lighter than a large bottle of water.

To answer your question, we need to clarify what you mean by "lighter":

* Lighter in density: Water is generally denser than wine.

* Lighter in weight: Depends on the volume of each.

* Lighter in color: White wine is generally lighter in color than red wine.

Please clarify your question so I can give you a more specific answer!
