Much of the food we eat contains yeast, and the same is true for alcohol. Normal amounts of yeast are fine, but yeast contains bacteria that, if not processed correctly by your body, can cause infections. In this case, some doctors will recommend a yeast-free diet. If you drink alcohol, this could be a disappointment. However, there are some alcoholic beverages that are free of yeast.


Wine

Wine, red or white, is almost completely free of yeast by the time a winery bottles the product. Yeast is used to initially color and flavor the wine, but in order to make the wine clear, it has to go through a filtration process that clears out the yeast. If yeast were to remain in wine, the wine would become cloudy and distasteful over time. This is because the yeast would continue to allow the wine to become more alcoholic.


Domestic Beer

U.S. law requires that all domestic beer be filtered and pasteurized. This means that the yeast is removed from the drink after the yeast has produced the desired color and alcohol level. However, this is only true for domestic beers. Imported beers, or beers that come from somewhere other than the U.S., do not have to abide by this law. If you are put on a yeast-free diet, you should only drink domestic beer.


Vodka

Vodka is considered the purest of all alcohol. Vodka goes through a rigorous distillation process that removes the yeast. Like wine, if yeast were to remain, the vodka would not remain clear. Vodka is recommended if you are on a yeast-free diet. The pureness of vodka also prevents hangovers.


Gin

Gin is another clear alcohol that is cleared of yeast by filtration before it is bottled. Gin is preservative free, but it is also known as a diuretic, so care should be taken when drinking gin. It is, however, a drink that can be consumed on a yeast-free diet.
