Overview
About Bourbon
Bourbon is a corn-based whiskey, and because distillation leaves the gluten protein behind in the mash, the spirit itself is gluten-free even though it starts from grain.
The catch is the alcohol: bourbon is graded a strong histamine liberator, which is why a couple of pours can bring on flushing, a stuffy nose or a headache even though the whiskey carries little histamine of its own. It is low FODMAP and clean on lactose and dairy, so the trigger story here is almost entirely about the ethanol, not the grain.

Watch for
What trips people up
- Strong histamine liberator: the alcohol prompts your body to release its own stored histamine and slows the DAO enzyme that clears it, so flushing, congestion and headaches are common even from a small measure.
- Gluten-free by distillation. Bourbon is made from corn and other grains, but the gluten protein stays behind in fermentation, so the spirit is safe for most people avoiding gluten. Watch only for flavored bottles with ingredients added after distilling.
- Graded pro-inflammatory and poor for SIBO, so it can aggravate a sensitive or overgrown gut even in modest amounts.
- Only borderline on sulfites, salicylates and tyramine, a lighter load there than wine, but still worth watching if you stack several drinks.

FAQ
Common questions about Bourbon
Is bourbon gluten-free?
Yes. Bourbon is distilled from a corn-heavy grain mash, and distillation leaves the gluten protein behind, so the finished spirit is gluten-free and safe for most people with celiac disease or gluten sensitivity. The exception is flavored or infused bottles that add barley malt or other ingredients after distilling, so check the label if a bourbon lists anything beyond the base spirit.
Why does bourbon make me flushed or give me a headache?
Bourbon is graded a strong histamine liberator. Alcohol prompts your body to release stored histamine and blunts diamine oxidase (DAO), the enzyme that breaks histamine down, so histamine climbs and you get flushing, a blocked nose or a headache. People with histamine intolerance tend to feel this from spirits more than the small amount of histamine actually in the drink would suggest.
Is bourbon lower in histamine than wine or beer?
The spirit itself carries very little preformed histamine, because distillation strips most of it out, so bourbon is lower in histamine than red wine or beer. But it is still alcohol, so the liberator effect remains. If histamine is your issue, a clear unaged spirit like vodka is usually the gentler choice.
