Jameson is a triple-distilled Irish whiskey; Jack Daniel’s Old No. 7 is a charcoal-mellowed Tennessee whiskey. Both are bottled at 40% ABV (80 proof) in the US, and both are among the best-selling whiskeys in the world, but they come from different countries, different grains and different legal rules. Jameson tastes lighter, smoother and more floral. Jack Daniel’s tastes sweeter and richer, with banana, caramel and charred-oak notes.
Below you will find a side-by-side comparison, how each is made, how they taste, and which one to choose for the way you drink.

How Jameson Is Made
Jameson traces its history to John Jameson’s Bow Street distillery in Dublin, founded in 1780. Since 1975 the whiskey has been made at the Midleton Distillery in County Cork. Pernod Ricard became the owner when it took over Irish Distillers in 1988.
Jameson Original blends two styles of whiskey. The first is single pot still whiskey, a distinctly Irish style made from a mix of malted and unmalted barley, which gives a creamy, spicy texture. The second is grain whiskey, which is lighter and smoother. Both are triple distilled, one more distillation than most Scotch and American whiskeys receive, which contributes to Jameson’s light, clean character.
To carry the name “Irish whiskey,” the spirit must meet the Irish Whiskey Act, 1980. The law requires distillation in the Republic of Ireland or Northern Ireland from a cereal mash and maturation in wooden casks for at least three years. Jameson’s own product listings state that Jameson Original is aged at least four years.
How Jack Daniel’s Is Made
Jack Daniel’s distills in Lynchburg, Tennessee, and the company lists its distillery as established in 1866. Brown-Forman owns the brand.
The mash for Old No. 7 is mostly corn, with smaller amounts of malted barley and rye. Corn gives the whiskey its sweetness. Jack Daniel’s uses the sour mash process, in which some spent mash from a previous batch goes into each new fermentation to control acidity and keep batches consistent.
The defining step comes after distillation. The new spirit drips slowly through about ten feet of packed sugar maple charcoal before it goes into the barrel. This charcoal mellowing, known as the Lincoln County Process, removes some harsher compounds and gives Tennessee whiskey its signature smoothness. A 2013 Tennessee law requires whiskey labeled “Tennessee whiskey” to be made in Tennessee from a mash of at least 51% corn, filtered through maple charcoal before aging, and aged in new charred oak barrels.
How They Taste
Jameson Original
Jameson opens with a light, floral aroma and a touch of sweetness. On the palate, the brand describes spice, nuttiness and vanilla with hints of sweet sherry, and a smooth finish. It is light-bodied and easy to drink neat, which is why it often serves as an introduction to whiskey.
Jack Daniel’s Old No. 7
Jack Daniel’s is fuller and sweeter. Expect caramel, vanilla and toasted oak from the new charred barrels, along with a distinctive ripe-banana note that many drinkers associate with the brand, and a warm finish. The corn-heavy mash and new barrels give it more body and sweetness than Jameson.

Which Should You Choose?
- For sipping neat as a beginner: Jameson. It is lighter and less sweet, with fewer bold oak notes.
- With cola: Jack Daniel’s. Its caramel and vanilla flavors pair naturally with cola, and Jack and Coke is one of the most ordered drinks in the world.
- With ginger ale: Jameson. The brand’s signature serve is Jameson, ginger ale and a lime wedge over ice.
- In a Whiskey Sour or Old Fashioned: Either works. Jack Daniel’s gives a sweeter, richer drink; Jameson gives a lighter, brighter one.
- In an Irish Coffee: Jameson, since the drink calls for Irish whiskey.
Two Easy Serves
Jameson, Ginger and Lime
- 1.5 oz Jameson Original
- 4 oz ginger ale
- 1 lime wedge
Fill a highball glass with ice, add Jameson, top with ginger ale, then squeeze in the lime and drop it into the glass.
Jack and Coke
- 1.5 oz Jack Daniel’s Old No. 7
- 4 oz cola
- Lime wedge (optional)
Build over ice in a highball glass and stir briefly. A squeeze of lime cuts the sweetness.
Beyond the Flagship Bottles
Both brands sell wider ranges. Jameson offers richer expressions such as Black Barrel alongside the Original. Jack Daniel’s sells Gentleman Jack, which is charcoal mellowed twice, plus flavored products such as Tennessee Honey, Tennessee Fire and Tennessee Apple. Those flavored Jack Daniel’s products are bottled at 35% ABV, lower than Old No. 7, and are sold as whiskey liqueurs or specialty products rather than straight whiskey. Bonded and single barrel bottlings are stronger. Always check the strength on the specific bottle. Read our guide to Gentleman Jack for more.
Strength and Serving Size
At 40% ABV, a 1.5-ounce pour of either whiskey equals one US standard drink of 14 grams of alcohol. A 750 mL bottle of either holds about 17 standard drinks. For more on serving math, see how much whiskey it takes to feel the effects.

Frequently Asked Questions

Most drinkers find Jameson lighter and smoother, thanks to triple distillation and a less sweet, less oak-heavy profile. Jack Daniel’s is smooth too, but fuller and sweeter.
Is Jack Daniel’s a bourbon?
Jack Daniel’s labels itself Tennessee whiskey, not bourbon. It shares bourbon’s corn-heavy mash and new charred oak barrels, but adds sugar maple charcoal mellowing before aging, which is part of the Tennessee whiskey definition under state law.
Which is stronger, Jameson or Jack Daniel’s?
Neither. The flagship bottles of both are 40% ABV (80 proof) in the US.
Is Jameson Scotch?
No. Jameson is Irish whiskey, made in Ireland under Irish law. Scotch must be made in Scotland.
