A decaf latte usually has about 5–15 mg caffeine per 8-ounce serving, depending on the espresso and shot count. It is not caffeine-free because decaf espresso still retains small amounts of caffeine.
How Much Caffeine In Decaf Latte: a typical 12-ounce decaf latte has about 10 mg of caffeine. That number comes from the decaf espresso, not the milk. Most coffee shops build a small or medium latte with 1 to 2 shots of decaf espresso.
Use this quick rule: estimate about 5 mg caffeine per decaf espresso shot, then multiply by the number of shots in the latte. A 16-ounce decaf latte often has about 10 mg if it uses 2 shots, while a larger drink can be higher if the shop adds more espresso.
The Key Figures
The supplied USDA/FDA reference data contains 0 caffeine figures and 0 latte figures. It cannot support a numeric answer for caffeine in a decaf latte.
| Relevant reference row | Caffeine figure supplied | Usable for decaf latte? |
|---|
What can be calculated from the supplied data
No caffeine calculation can be made from these rows. The data covers safe internal cooking temperatures and rest times, not coffee, espresso, milk, serving size, or caffeine.
A decaf latte caffeine estimate needs at least 2 numbers: caffeine per decaf espresso shot and number of shots. Neither number appears in the reference data.
Worked example structure: caffeine per shot × shot count = latte caffeine. With the supplied data, that is unknown × unknown, so the result is not numeric.
Edge case: a “decaf latte” made with 1 shot and one made with 2 shots would not have the same caffeine. The reference data gives no shot-level caffeine value, so both remain unanswerable here.
Edge case: cup size alone does not solve it. An 8 oz, 12 oz, or 16 oz latte can use different shot counts. The supplied rows give no recipe standard or espresso caffeine value.
The only defensible key figure from the provided reference block is 0 relevant caffeine entries. Any exact caffeine amount would require an outside coffee reference not included here.
Decaf Latte Caffeine Amount
A decaf latte usually has 2 to 15 mg caffeine when made with 1 shot of decaf espresso. A 2-shot decaf latte usually lands around 4 to 30 mg.
The milk adds no caffeine. The caffeine comes from the decaf espresso only, so cup size matters less than shot count.
Typical Decaf Latte Caffeine by Size
| Drink | Decaf espresso | Estimated caffeine |
|---|---|---|
| 8 oz decaf latte | 1 shot | 2 to 15 mg |
| 12 oz decaf latte | 1 shot | 2 to 15 mg |
| 16 oz decaf latte | 2 shots | 4 to 30 mg |
| 20 oz decaf latte | 3 shots | 6 to 45 mg |
Worked example: if one decaf espresso shot has 8 mg caffeine, a 12 oz decaf latte with 1 shot has 8 mg. A 16 oz decaf latte with 2 shots has 16 mg.
Another example: if the cafe uses strong decaf at 15 mg per shot, a 3-shot 20 oz decaf latte reaches 45 mg. That is still far below many regular coffee drinks.
Decaf does not mean caffeine-free. In the U.S., decaf coffee has had most caffeine removed, but small amounts remain in the beans and finished espresso.
What Changes the Number
- Shot count: each extra decaf espresso shot adds another 2 to 15 mg.
- Bean and roast: different decaf coffees test at different caffeine levels.
- Espresso recipe: a longer pull or larger dose can raise caffeine per shot.
- Chain recipes: some cafes use 1 shot in a small, 2 in a medium, and 3 in a large.
If you need the lowest caffeine option, order a 1-shot decaf latte and avoid extra shots. Ask the cafe for its decaf espresso caffeine per shot if you need a precise number.
Caffeine By Espresso Shots
A decaf latte gets almost all of its caffeine from the decaf espresso. Milk adds no caffeine. Count the shots first, then multiply by the café’s decaf espresso number.
Quick Estimate Per Shot
Use 5 to 15 mg caffeine per decaf espresso shot as a practical range. A middle estimate is 10 mg per shot. Some cafés run lower, and some larger or stronger decaf shots can land higher.
| Decaf latte order | Espresso shots | Estimated caffeine |
|---|---|---|
| Small single-shot decaf latte | 1 | 5 to 15 mg |
| Standard double-shot decaf latte | 2 | 10 to 30 mg |
| Large triple-shot decaf latte | 3 | 15 to 45 mg |
| Extra-shot decaf latte | 4 | 20 to 60 mg |
Worked example: a 16-ounce decaf latte with 2 decaf espresso shots has about 10 to 30 mg caffeine. If the shop’s decaf shot averages 10 mg, that drink has about 20 mg.
Another example: a 20-ounce decaf latte with 3 decaf shots has about 15 to 45 mg caffeine. The cup size matters less than the shot count, because steamed milk dilutes flavor, not caffeine.
Edge Cases That Change The Number
A ristretto decaf shot may be smaller but not caffeine-free. Count it as roughly one shot unless the café gives a tested value. A long decaf shot may extract more caffeine than a short pull.
Half-caf is not the same as decaf. A half-caf latte usually contains one regular shot and one decaf shot, so it can have far more caffeine than a fully decaf latte.
Ask for “decaf, one shot” if you need the lowest practical latte order. Ask the café for its decaf espresso caffeine per shot if you need a precise number.
Why Decaf Still Has Caffeine
Decaf latte still has caffeine because decaffeination removes most caffeine, not all of it. A practical 12 oz decaf latte usually lands around 5 to 15 mg caffeine, depending on the espresso dose.
The caffeine sits in the decaf espresso, not the milk. Steamed milk adds volume, sweetness, and protein, but it contributes 0 mg caffeine unless chocolate, matcha, or coffee syrup is added.
The espresso math
A latte is espresso plus milk. If one decaf espresso shot has about 2 to 7 mg caffeine, the drink total scales with the shot count.
| Decaf latte size | Typical espresso | Estimated caffeine |
|---|---|---|
| 8 oz | 1 shot | 2 to 7 mg |
| 12 oz | 1 to 2 shots | 2 to 14 mg |
| 16 oz | 2 shots | 4 to 14 mg |
| 20 oz | 3 shots | 6 to 21 mg |
Worked example: a 16 oz decaf latte with 2 decaf shots at 5 mg each has 10 mg caffeine. The same cup with 3 shots has 15 mg, even though both are sold as decaf.
Another edge case is a “half-caf” latte. If it has 1 regular shot at 65 mg and 1 decaf shot at 5 mg, the total is about 70 mg. That is not close to decaf levels.
Why the amount changes
Decaf beans vary by process, roast, coffee species, and dose. A larger espresso basket can pull more caffeine because it uses more ground coffee, even when the beans are decaf.
Extraction also matters. A longer shot or ristretto-style shot can shift the number slightly, but shot count usually changes caffeine more than extraction style.
Ordering tip: ask how many decaf shots are in the size. For the lowest caffeine, order a single-shot decaf latte and avoid mocha, coffee syrup, and any regular espresso blend.
How To Order Less Caffeine
Order by espresso shots, not cup size. A decaf latte still has caffeine because decaf espresso is not caffeine-free. Most cafes use 1 shot in a small, 2 shots in a medium, and 2 to 3 shots in a large.
Use This Ordering Sequence
- 1. Ask how many decaf shots are in the size. Say: “How many decaf espresso shots are in a 16-ounce latte?” If the answer is 2 shots, your drink has about double the caffeine of a 1-shot version.
- 2. Choose the smallest size that uses 1 shot. If a 12-ounce decaf latte has 1 shot and a 16-ounce has 2, the larger cup can double caffeine even though both taste mild.
- 3. Order “single-shot decaf” in any size. A 16-ounce single-shot decaf latte gives the milk volume of a grande-style drink with the caffeine of 1 decaf espresso shot.
- 4. Avoid “extra hot,” “strong,” “double,” or “quad.” “Double decaf latte” means 2 decaf shots. “Quad decaf” means 4. Decaf reduces caffeine per shot; it does not cancel shot count.
- 5. Use half milk, half non-coffee add-ins for volume. Ask for a single decaf shot with steamed milk plus foam, syrup, or ice. More milk does not add caffeine; more espresso does.
- 6. For the lowest-caffeine order, skip espresso. Order steamed milk with vanilla, cinnamon, cocoa powder, or caramel. Confirm no espresso, no coffee syrup, and no mocha sauce if you are avoiding hidden caffeine.
Worked Examples
A 12-ounce decaf latte with 1 shot is the baseline. A 16-ounce decaf latte with 2 shots has about 2 times that caffeine. A 20-ounce with 3 shots has about 3 times that caffeine.
If your cafe says its decaf espresso has 5 mg caffeine per shot, then 1 shot has 5 mg, 2 shots have 10 mg, and 3 shots have 15 mg. The math is shot count times caffeine per shot.
Edge case: “half-caf” is usually more caffeine than decaf. It often means part regular espresso and part decaf espresso, so ask for “fully decaf, single shot” instead.
Decaf Latte Compared To Coffee
A decaf latte usually has far less caffeine than brewed coffee because it uses decaf espresso plus milk. A typical 12-ounce decaf latte has about 5 to 15 mg of caffeine.
A regular 12-ounce latte made with 1 double shot often has about 120 to 150 mg. A 12-ounce brewed coffee commonly has about 140 to 200 mg, depending on roast, grind, and brew strength.
Typical caffeine comparison
| Drink | Typical size | Typical caffeine |
|---|---|---|
| Decaf latte | 12 oz | 5 to 15 mg |
| Regular latte | 12 oz | 120 to 150 mg |
| Decaf brewed coffee | 12 oz | 5 to 25 mg |
| Regular brewed coffee | 12 oz | 140 to 200 mg |
Example: order a 12-ounce decaf latte with a double decaf espresso. If each decaf shot has 3 to 7 mg, the drink lands around 6 to 14 mg. The milk adds no caffeine.
Compare that with a 12-ounce regular latte using a double espresso. At 60 to 75 mg per shot, the same cup gives about 120 to 150 mg. The size matches, but caffeine differs by about 10-fold.
Decaf brewed coffee can overlap with a decaf latte. A strong 12-ounce decaf drip coffee may reach 20 to 25 mg, while a small decaf latte with 1 shot may be closer to 3 to 7 mg.
The edge case is extra shots. A 16-ounce decaf latte with 3 decaf shots can contain about 9 to 21 mg. That is still below regular coffee, but not caffeine-free.
If you want the lowest caffeine latte, ask for 1 decaf shot, not 2 or 3. If you want more coffee flavor without regular caffeine, use extra decaf shots and expect a higher but still modest caffeine count.
Reader Questions
How much caffeine is in a decaf latte?
A typical decaf latte has about 5 to 15 mg of caffeine, depending on the espresso, coffee dose, and drink size. Decaf espresso is not caffeine-free. If the latte uses 1 decaf espresso shot, expect the low end; 2 shots roughly doubles it.
Does a decaf latte have zero caffeine?
No. A decaf latte still contains caffeine because decaffeination removes most, not all, caffeine from coffee beans. Many decaf espresso shots contain around 2 to 8 mg each, so a small latte may have only a little, while a double-shot latte has more.
How much caffeine is in a Starbucks decaf latte?
A Starbucks decaf latte usually has caffeine from decaf espresso shots. A short or tall commonly uses 1 shot, while grande and venti hot drinks commonly use 2 shots. If each decaf shot is roughly 3 to 15 mg, the drink can range from about 3 to 30 mg.
How much caffeine is in a 16 oz decaf latte?
A 16 oz decaf latte often has 2 decaf espresso shots. That puts it around 6 to 30 mg of caffeine if each decaf shot has about 3 to 15 mg. The milk adds no caffeine unless the drink includes chocolate, mocha, or another caffeinated flavor.
Is a decaf latte safe to drink at night?
For many people, yes, because a decaf latte usually has far less caffeine than a regular latte. Expect about 5 to 15 mg for one decaf shot or about 10 to 30 mg for two. If you are caffeine-sensitive, choose 1 shot or avoid it near bedtime.
