Cognac vs Bourbon

Two oak-aged spirits with very different regulatory regimes. Bourbon is the most strictly regulated mainstream spirit — zero additives, by law. Cognac permits sugar dosage, caramel coloring, and oak extract within BNIC limits, and most major brands use all three.

Verdict

Bourbon wins on purity. Cognac is sweeter and "smoother" partly because of permitted additives; bourbon's character comes entirely from grain and barrel. Cognac also carries grape-derived histamines that bourbon doesn't.

FAQ

Is bourbon or cognac healthier?

Bourbon, narrowly. The no-additive rule outweighs cognac's smoother profile in chemistry terms. Cognac also carries grape histamines that bourbon doesn't.

Why is cognac smoother than bourbon?

Three reasons: longer aging, smaller charred oak fraction (used French oak vs new American), and permitted sugar dosage. The first two are chemistry; the third is added sweetness.
