- Yeast: Converts the natural sugars from the grain mash into alcohol during fermentation.
- Oak Barrels: While not an ingredient added to the mash, aging in wooden barrels (typically oak) imparts a significant portion of the flavor, color, and aroma.

Frequently Asked Questions: Shelf Life & Dietary Facts
Does Whiskey Go Bad?
Unopened bottles of whiskey have an virtually indefinite shelf life when stored properly in a cool, dark place out of direct sunlight. Because of its high alcohol content (typically 40% ABV or higher), unopened whiskey does not spoil or mature further inside the glass bottle.
Once a bottle is open, oxidation begins. An opened bottle with a high liquid level remains excellent for 1 to 2 years. If less than a quarter of the bottle remains, oxidation accelerates, and the flavor profile may begin to flatten after 3 to 6 months.
Is Whiskey Gluten Free?
Yes, pure distilled whiskey is consider gluten-free. Even though whiskey can be from gluten-containing grains such as wheat, barley, or rye, the distillation process removes gluten proteins from the final liquid.
Note: Individuals with severe celiac disease or gluten sensitivities should exercise caution with flavored whiskies or spirits where post-distillation additives or cross-contamination might occur.
