Wheat Whiskey Explained

A whiskey made from 100% malted soft red winter wheat contains no corn at all. That is one of the two recipes behind Maker’s Mark’s Star Hill Farm American Wheat Whisky, and it captures the distinction at the heart of this category: wheat takes the lead, rather than playing a supporting role.[4]

US federal rules define wheat whiskey by a fermented mash containing at least 51% wheat, followed by distillation and storage within specified limits. Wheated bourbon is different: bourbon must contain at least 51% corn, with wheat taking a secondary role in a wheated recipe.[1][3]

What makes wheat whiskey wheat whiskey?

Wheat must supply the majority of the grain recipe, often called the mash bill. Under the US standard, it must account for at least 51% of the fermented mash. Other grains can make up the rest, so wheat whiskey need not be made entirely from wheat.[1]

Distillation and the barrel complete the definition. Wheat whiskey must be distilled at no more than 80% ABV (160 US proof) and put into charred new oak barrels at no more than 62.5% ABV (125 US proof). The category does not permit neutral spirits.[1]

These US federal category rules are checked against the supplied official text dated 3 November 2026. The regulation spells the category “wheat whisky”; this article uses wheat whiskey in its own prose, following American category usage.[1]

Wheat whiskey and straight wheat whiskey

“Straight” adds two important requirements: at least two years in charred new oak, and no colouring, flavouring or blending materials. It does not change the majority grain. Ordinary wheat whiskey may contain those materials, an important difference from bourbon.[1]

Source: 27 CFR 5.143, Table 1, rows 2 and 5, text dated 3 November 2026.[1]

Read the two words separately. “Wheat” identifies the majority grain; “straight” tells you more about storage and additions. Neither replaces an age statement. In the United States, whisky aged under four years generally requires one, subject to the exceptions in 27 CFR 5.74.[6] For the designation’s wider meaning across American categories, see what makes a whiskey straight.[1]

Wheat whiskey versus wheated bourbon

The difference is which grain leads the recipe. Wheat whiskey requires at least 51% wheat. Wheated bourbon remains corn-led, with at least 51% corn and wheat as a secondary grain. Giving wheat a prominent place in a bourbon’s description does not turn it into wheat whiskey.[1][3]

Maker’s Mark offers a clear example. The producer describes its bourbon as made with soft red winter wheat instead of the usual rye. “Wheated” describes that recipe; it is not a legal category in the United States and does not change the spirit’s identity as bourbon.[1][3]

The distinction reaches beyond the grain. Bourbon cannot contain colouring, flavouring or blending materials, while ordinary wheat whiskey permits them. Straight wheat whiskey excludes those additions. Reading the complete designation tells you which rules apply, rather than leaving you to assume that every wheat whiskey follows bourbon’s restrictions.[1]

For a closer look at wheat’s supporting role, the separate guide to wheated bourbon follows that corn-led style. Here, the defining question is simpler: does wheat itself supply the majority of the mash?

Three named examples, three useful distinctions

A complete category name, a published grain recipe and an attributed flavour description each reveal something different about a whiskey. These three producer descriptions show how to read those details. They are examples, not a ranking.

Bernheim Original: a straight wheat whiskey

Heaven Hill describes Bernheim Original as a seven-year-old straight wheat whiskey, bottled at 45% ABV (90 US proof) and distilled at the Bernheim Distillery in Louisville. In one description, the producer supplies the grain category, straight designation, age, bottling strength and named distillery.[2]

The key words are “straight wheat whiskey”. They establish more than “wheat whiskey” alone: the US straight standard requires at least two years in charred new oak and excludes colouring, flavouring and blending materials. Bernheim’s seven-year statement adds a separate piece of product information supplied by Heaven Hill, beyond the category’s minimum ageing requirement.[1][2]

Star Hill Farm: two wheat-led mash bills

Maker’s Mark’s Star Hill Farm American Wheat Whisky shows how much room there is within the category. The producer describes two mash bills: one with 70% soft red winter wheat and 30% malted barley, the other with 100% malted soft red winter wheat. Neither contains corn.[4]

Set those recipes beside the producer’s wheated bourbon and the distinction becomes clear. Wheat supports corn in the bourbon; in both Star Hill Farm recipes, wheat is the majority grain. Its presence alone is not what separates the categories. Its proportion in the mash is what matters.[3][4]

The producer describes the 2025 Star Hill Farm release as a blend of seven and eight year old whiskies, bottled at cask strength. Its published tasting notes appear below as the producer’s account of that release, rather than a tasting conducted by this site.[4]

Dry Fly: an all-wheat example

Dry Fly describes Washington Wheat Whiskey as its original whiskey and as a 100% wheat whiskey. Here, every part of the grain recipe is wheat. That is the producer’s choice, not the minimum demanded by the federal category.[1][5]

Alongside Star Hill Farm’s 70% wheat recipe, Dry Fly makes a useful comparison. Both recipes put wheat first, but only one is all wheat. The category name establishes a wheat majority; the producer’s published mash bill supplies the finer detail, including whether any other grains are involved.[1][4][5]

What does wheat whiskey taste like?

The clearest answer comes from individual bottles, not a single flavour assigned to wheat. Maker’s Mark attributes the “front-of-palate sweetness” of its bourbon to red winter wheat. That is the producer’s description of its own whiskey, rather than a rule that every wheat whiskey tastes sweet.[3]

Star Hill Farm’s published notes are more specific. The producer lists “buttery caramel”, “golden raisins” and “gingerbread” on the nose; “honeyed toffee”, “chocolate covered cherries” and “apple pie spice” on the palate; and “toasted pecans” and “soft cinnamon” on the finish. Those descriptions belong to that release, not to the legal category as a whole.[4]

Dry Fly takes a broader approach, describing Washington Wheat Whiskey as “mellow, sweet, and easy drinking”. This is how the producer presents its product, rather than a description that can be applied to every recipe led by wheat.[5]

Keep the mash bill and the tasting note in their separate roles. A published wheat percentage answers a concrete question about grain balance. An attributed tasting note gives the producer’s sensory account of a particular whiskey. Together they make a more useful description than either can provide alone, but one does not establish the other.[1][3][4][5]

Similar label terms that mean something different

An extra word on the label can change the barrel requirement, the composition of a blend or the rules on additions. US federal regulations distinguish wheat whiskey from several related designations, each with its own meaning.[1]

Whisky distilled from wheat mash requires at least 51% wheat, but specifies storage in used oak barrels. Wheat whiskey requires charred new oak. The grain threshold is the same; the barrel requirement makes these different designations.[1]

Blended wheat whisky must contain at least 51% straight wheat whiskey on a proof gallon basis and may contain up to 49% neutral spirits. These percentages describe the blend on the regulation’s stated basis. They do not describe the proportion of wheat in the grain recipe.[1]

Blended straight wheat whiskies is a separate designation again. The regulation covers straight wheat whiskies from different states, or straight wheat whiskies from one state combined with colouring, flavouring or blending material. It is distinct from blended wheat whisky, with that designation’s allowance for neutral spirits.[1]

Origin also matters. Wheat whisky belongs to the regulation’s group of distinctive US types. When made abroad, it requires the country of origin next to the type designation or the words “American type”. Meeting the wheat percentage does not, by itself, answer that labelling question.[1]

In short: common mistakes when reading the category

A grain name tells you something important, but it is not a complete product description. Keep these three distinctions in mind when reading a label or a producer’s account:

• Wheat whiskey is not necessarily all wheat. The US minimum is 51%; an all-wheat recipe goes beyond that threshold.[1]
• Wheated bourbon is not wheat whiskey. Its majority grain remains corn, even when wheat replaces rye in the recipe.[1][3]
• Wheat whiskey does not follow every bourbon restriction. Ordinary wheat whiskey permits colouring, flavouring and blending materials; straight wheat whiskey does not.[1]
