Does soda weigh more than water?

Alcohol found in Alcoholic Beverages is lighter than water. It is called ethanol.

But as far as chemistry is concerned alcohols are a large family of organic compounds. Alcohols are compounds whose molecules have a hydroxyl group attached to saturated carbon atom1 of a carbon chain. The chain may be short or long. Most monohydroxy alcohols are lighter than water. Some Diols(containing two hydroxyl groups ) and Triols(containing three hydroxyl groups ) are heavier than water.

Example of diol heavier than water- ethylene glycol.

Example of triol heavier than water-glycerol.
