Given that it just requires water, wheat, rye, and barley as its only four ingredients, vodka is regarded as the purest of all distilled spirits. Other distilled beverages, like as whiskey and bourbon, are produced using a variety of grains and may incorporate other flavors that alter the flavor.
Adding water to alcohol doesn't reduce the amount of acohol in your drink. If you had a glass o vodka, 80% proof, and added a glass of water, you still have the same amount of alcohol. If you drink the combination, you still have consumed the same amount of alcohol.
For getting a little drunk, three shots of vodka are enough. If you continue to drink up to 8 to 9 shots, that's when they start getting more drunk. The upper cap for men is ten shots of vodka. Exceeding this, they will be extremely drunk.
