The rules make the flavor: bourbon must be made in the U.S. from at least 51% corn, aged in new charred oak barrels, with nothing added but water. The mash bill is where distilleries show their hand — wheated bourbons swap rye for wheat for a soft, sweet sip, while high-rye bourbons bring pepper and spice. Most bourbon still comes from Kentucky, but standout distilleries now craft it across the country.
When you shop bourbon online, learn the labels: bottled in bond means 100 proof, at least 4 years old, from a single distillery — a historic quality mark. Barrel proof is undiluted and bold. And do not overlook bottles with no age statement — many are batched for flavor, not the calendar. Our shelves carry the distilleries bourbon hunters ask for — Buffalo Trace, Woodford Reserve, Wild Turkey, Four Roses — including the allocated bottles that disappear fast.
Every bourbon here is available to order online at Del Mesa Liquor, shipping from San Diego, CA. Neat pour, old fashioned, or the top shelf of your dreams — start here.
Bourbon FAQs
What makes bourbon different from whiskey?
Bourbon is a type of whiskey with strict rules: made in the U.S., at least 51% corn, aged in new charred oak barrels, and bottled at no less than 80 proof with no added flavoring or coloring.
Is Jack Daniel's bourbon?
Jack Daniel's meets the legal requirements for bourbon, but it is marketed as Tennessee whiskey because of the Lincoln County Process — charcoal filtering before barreling — that defines the Tennessee style.
What is the best bourbon for an old fashioned?
A high-rye or 100-proof bourbon. The extra spice and proof stand up to sugar and bitters instead of getting lost in them.
Why is some bourbon so hard to find?
Top distilleries can only age what they barreled years ago, and demand has outpaced supply. Allocated bottles go to stores in small quantities — when you see one in stock, do not wait.
What Makes It Bourbon
Bourbon is America's native spirit, and the law is specific: it must be made in the United States from at least 51% corn, distilled to no more than 160 proof, entered into new, charred oak barrels at no more than 125 proof, and bottled at 80 proof or higher. No flavoring, no coloring, no shortcuts — everything in the glass comes from grain, water, yeast, and that fresh charred barrel. The corn gives bourbon its signature sweetness: caramel, vanilla, and baking spice over a backbone of oak. Most of it still comes from Kentucky, where limestone-filtered water and hot summers that push whiskey deep into the barrel staves have made it the spirit's home for two centuries.
Small Batch, Single Barrel, Barrel Proof
Within bourbon, three phrases tell you how a bottle was built. Small batch means the bottling blended a limited number of selected barrels — Colonel E.H. Taylor Jr. Small Batch ($59.99) is the benchmark. Single barrel means exactly that: one barrel, no blending to hide behind, like Blanton's Single Barrel ($94.99), the bottle that started the category in 1984. Barrel proof (or cask strength) means the whiskey went into the bottle uncut, the way it came out of the barrel — Elijah Craig Barrel Proof is the connoisseur's favorite example. Age statements still matter too: Knob Creek 12 Year Old ($69.99) shows what patient Kentucky aging does.

Frequently Asked Questions
Does bourbon have to come from Kentucky?
No. Federal law requires bourbon to be made in the United States, but it can be produced in any state — Texas, Nevada, and Indiana all make respected bourbons. Kentucky simply makes the most, and most of the famous names.
What's the difference between bourbon and Tennessee whiskey?
Tennessee whiskey starts as bourbon-style whiskey, then gets filtered through sugar maple charcoal before aging — the Lincoln County Process. It adds a mellowing step bourbon doesn't require.
What does "barrel proof" mean?
The whiskey was bottled at the strength it reached in the barrel, without water added to bring the proof down. Expect bigger flavor and higher alcohol — most drinkers add a splash of water or a large cube.
What's a good first bourbon?
Buffalo Trace. It's soft, sweet, and balanced enough to sip neat, but structured enough for cocktails — and at $24.99 it's the bottle we recommend to anyone starting out.
How should I store an opened bottle?
Upright (so the spirit doesn't eat the cork), away from sunlight and heat swings. Opened bourbon keeps its character for a year or more; very old, nearly empty bottles are best finished sooner.
