I assume that by "boils faster" you really mean "boils at a lower temperature", and that by "alcohol" you mean "ethanol".

Ethanol has a lower boiling temperature than water at standard pressure. However, a mixture of ethanol and water boils lower than either by themselves do. This is called an "azeotrope" and it happens for ethanol/water mixtures at about 95% ethanol, which is why it's essentially impossible to get ethanol to more than 190 proof by distillation alone.

Alcohol has a lower boiling point than water. Naturally the alcohol evaporates leaving the flavanoids and the water. If you boil 100 % alcohol, then it would act like plain water. It will boil until it all evaporates.

Can alcohol and water be seperated by physical means?

Sure! It's called distillation and it's done all the time, especially in Kentucky. Alcohol's boiling point is lower than water's is. If you heat an alcohol-water solution to alcohol's boiling point, the alcohol will boil off leaving the water behind.
