What is vodka beers?

As an AI language model, I do not have information on "vodka beers," as this seems to be a misnomer or a confusion between two different alcoholic beverages. Vodka is a distilled spirit made from grains or potatoes, whereas beer is a fermented beverage made from malted grains and hops. These two drinks have different production methods, ingredients, and alcohol content.

However, it is possible that you are referring to beer cocktails that contain vodka as one of their ingredients. Some popular examples of these drinks are the Black and Tan (a mix of stout and pale ale with a shot of vodka), the Boilermaker (a shot of vodka dropped into a glass of beer), and the Michelada (a beer mixed with tomato juice, lime, hot sauce, and vodka). While these cocktails can be tasty and refreshing, they should be consumed in moderation, as the combination of different types of alcohol can increase the risk of intoxication and hangover.
