Q10. Ans:

No.

Alcohol level is, everything else being equal, mainly a result of the amount of sugar in the grapes. Warmer climates tend to allow for higher alcohol levels as the growing season is often longer.

As an example, California wines tend to be relatively high in alcohol, 14.5% being no exception. Burgundy on the other hand is a much cooler climate, and wines usually are much lower in alcohol. Overall, Burgundy Pinot Noirs are much more expensive though than California Pinot Noirs.

Q21. Ans:Hydrometers are used to measure the specific gravity (relative density) of liquids - the ratio of the density of the liquid to the density of water. Here, the white wine is denser as it contains more sugars than the red wine.
