The Grain Foundation of Whiskey
Every whiskey starts with a mash bill, which is the specific recipe or mix of grains fermented to produce the spirit. The grain selection is a foundational element that dictates the whiskey's overall character, taste, and texture. While iconic spirits like single malt Scotch are made exclusively from malted barley, and bourbon requires at least 51% corn, the modern whiskey landscape is rich with diversity. Wheat is one of the four most common whiskey grains, alongside corn, rye, and barley.
Where Wheat Appears in Whiskey
Wheat is a common component in several whiskey styles, where it lends a smooth, sweet, and mellow profile.
- Wheated Bourbon: In the United States, bourbon must be at least 51% corn. Wheated bourbons, such as Maker's Mark, replace the typical rye grain in the remaining mash bill with wheat. This substitution results in a softer, sweeter, and more approachable spirit with notes of caramel, vanilla, and honey, as the wheat's mild flavor allows the corn's inherent sweetness to shine.
- Wheat Whiskey: A less common but distinct category, wheat whiskey is made from a mash bill containing at least 51% wheat. These spirits are known for being exceptionally smooth and mild, with sweet, bready, and honey-like characteristics. Examples include Bernheim Original and some craft distillery offerings.
- Grain Scotch Whisky: In Scotland, grain whisky—used primarily for blended Scotch—is often distilled from a mash of cereals that can include wheat or maize, combined with a small amount of malted barley. The wheat varieties used are often selected for their high alcohol yield and balanced flavor profile.
- Canadian Whisky: The rules for Canadian whisky are more flexible, and many brands feature a blend of grains, with wheat being a common ingredient. This contributes to the typically light, smooth, and approachable character of Canadian spirits.
The Flavor Impact: Wheat vs. Other Grains
The choice of grain is not a minor detail; it is a fundamental decision that defines the final spirit's aromatic and flavor profile. Below is a comparison of how wheat stacks up against the other major whiskey grains.
| Grain | Flavor Profile | Texture | Common Usage |
|---|---|---|---|
| Wheat | Soft, smooth, mellow, honey, vanilla, light fruit, bread | Creamy, velvety | Wheated Bourbons, Wheat Whiskey, Blended Scotch, Canadian Whisky |
| Corn | Sweet, rich, caramel, vanilla, butterscotch | Full-bodied, heavy | Bourbons (primary grain) |
| Rye | Spicy, peppery, clove, cinnamon, herbal, fruity | Dry, crisp | Rye Whiskey (primary grain), High-Rye Bourbons, Canadian Whisky |
| Barley | Malty, nutty, toffee, cereal sweetness | Smooth, complex | Scotch (primary grain), Irish Whiskey, Malt Whiskey |
The Distilling Process and Wheat
The physical properties of wheat also impact the distilling process. Its softness and gluten content can make milling and mashing challenging, sometimes creating a thick, sticky mash that can clog equipment. To mitigate this, many distillers use malted barley, which contains the necessary enzymes to convert starches into sugars, or they may add artificial enzymes. The distillation process itself is also crucial. Whiskeys distilled in continuous column stills, a common method for grain whiskies, tend to be lighter and cleaner than those made in traditional pot stills.
This is where much of the artistry lies for a master distiller—managing the tricky-to-work-with wheat to unlock its desirable flavor characteristics while avoiding processing pitfalls.
Conclusion: The Gentle Grain's Signature
The answer to the question "Does whiskey use wheat?" is a resounding yes, although its role is dependent on the specific type and regional style. From the famously smooth wheated bourbons that have cultivated a devoted following to the lighter, cleaner grain whiskies found in many blends, wheat offers a distinctly different, more mellow expression than its spicier rye or more assertive corn and barley counterparts. The gentle, sweeter notes it imparts provide a smooth and approachable entry point for many whiskey enthusiasts and a welcome balance in complex blends. Next time you enjoy a glass, consider the nuanced contribution of each grain in the mash bill, especially the creamy, bread-like smoothness that wheat brings to the mix. A deep appreciation for this ingredient will undoubtedly enhance your tasting experience.

Key Takeaways
- Yes, whiskey can use wheat: Wheat is a standard grain used in the production of many whiskies, particularly wheated bourbons, wheat whiskey, and some blended grain spirits.
- Softens and sweetens the flavor: Wheat lends a smooth, mellow, and often sweeter flavor profile to whiskies, with notes of honey, vanilla, and baked bread.
- Distinguishes wheated bourbon: In bourbon, wheat is used as a secondary flavoring grain instead of rye, resulting in a less spicy, more approachable taste compared to traditional high-rye bourbons.
- Primary grain for Wheat Whiskey: By law, any spirit labeled as “Wheat Whiskey” must be distilled from a mash bill of at least 51% wheat.
- Found in blended spirits: Wheat is a common ingredient in blended whiskies, including many Canadian and blended Scotch whiskies, contributing to their overall lightness and smoothness.
FAQs
What grains are used to make whiskey? Whiskey can be made from a variety of cereal grains, including barley (malted and unmalted), corn, rye, and wheat. The specific blend of grains, known as the mash bill, determines the style of the whiskey.
What is the difference between a high-rye bourbon and a wheated bourbon? A high-rye bourbon uses rye as its secondary flavoring grain, giving it a spicier, more intense flavor. A wheated bourbon substitutes wheat for the rye, resulting in a sweeter, softer, and smoother spirit.
Does wheat whiskey taste different from wheated bourbon? Yes. While both feature wheat, a wheated bourbon must contain at least 51% corn, with wheat as a secondary grain. A wheat whiskey must be made with at least 51% wheat, resulting in an even milder and smoother flavor profile where the wheat's character is more dominant.
Is wheat used in Scotch whisky? Yes, wheat is a key ingredient in grain Scotch whisky, which is then typically blended with single malt whiskies to create blended Scotch. Single malt Scotch, however, is made exclusively from 100% malted barley.
What are some popular wheated bourbon brands? Well-known wheated bourbon brands include Maker's Mark, W.L. Weller, Pappy Van Winkle's Family Reserve, and Larceny.
Why is wheat a challenging grain for distillers? Wheat's soft texture and high gluten content can make it difficult to mill and can result in a thick, gummy mash that can clog stills. Distillers often use malted barley or added enzymes to aid in the fermentation process.
Is it possible to have a whiskey made with a blend of wheat and rye? Yes, it is possible. Some distillers create a four-grain bourbon mash bill that includes corn, rye, wheat, and malted barley. This combination aims to achieve a balance of flavors, leveraging the sweetness of corn and wheat with the spice of rye.
What flavor notes does wheat contribute to whiskey? Wheat typically imparts notes of honey, vanilla, light fruit, and a pleasant baked bread or pastry character. Its main contribution is a softer, more approachable flavor and a creamy mouthfeel.
How does wheat compare to barley in flavor? Barley provides a richer, more malty, and complex flavor with nutty notes, while wheat delivers a smoother, milder, and sweeter taste. The difference is akin to comparing a rich brown bread (barley) with a soft white bread (wheat).
