How Much Caffeine In Decaf Pumpkin Spice Latte? | Size Math

A decaf pumpkin spice latte still has a little caffeine, usually around 2 to 5 mg in a Starbucks-style drink.

If you want the fall flavor without a full coffee hit, a decaf pumpkin spice latte is one of the lighter picks on the menu. The catch is simple: decaf does not mean zero. There is still a trace left in the espresso, so the drink can matter if you’re extra sensitive to caffeine or you want a late-night cup.

For most café orders, the plain reading is this: expect a few milligrams, not a full buzz. Official Starbucks nutrition sheets list decaf Pumpkin Spice Latte builds from 1.8 mg to 5.4 mg, depending on size, market, and whether the drink is hot or iced. That is tiny next to a regular latte, but it is still real caffeine.

How Much Caffeine In Decaf Pumpkin Spice Latte? Size Changes The Number

The number stays low, but size still moves it. Smaller hot drinks land at the bottom of the range. Larger hot drinks creep up a bit. Big iced drinks can sit at the top, since some builds use more decaf espresso.

If you just want a fast read on your cup, this is the pattern most people care about:

• Short or tall hot decaf pumpkin spice lattes tend to land at the low end.
• Grande hot drinks usually sit in the middle of the range.
• Venti hot and venti iced drinks can sit at the top.
• Even at the top, you are still dealing with only a few milligrams.

Why Decaf Is Not Zero

That trace comes from the decaf espresso itself. The pumpkin sauce, milk, and topping build the flavor, but the coffee shot is what brings the caffeine. In plain terms, decaf coffee beans have most of their caffeine removed, not every last bit.

The FDA caffeine advice says decaf coffee still contains caffeine, and it puts a plain cup of decaf coffee at 2 to 15 mg per 8 ounces. A decaf pumpkin spice latte fits that same idea. It is low-caffeine, not caffeine-free.

Decaf Pumpkin Spice Latte Caffeine By Size And Style

Starbucks sheets from different markets tell a tight story. The Starbucks Austria autumn nutrition sheet lists hot decaf pumpkin spice latte builds as low as 1.8 mg for short and tall sizes, then 3.6 mg for grande and venti. The Starbucks Ireland autumn nutrition sheet lists tall and grande hot drinks at 3.6 mg and venti hot drinks at 5.4 mg, with iced venti drinks also at 5.4 mg.

The main thing to notice is not the tiny difference between 1.8 mg and 3.6 mg. It is the gap between a decaf version and a regular one. Once you swap in decaf espresso, the caffeine drops hard. That is why many people can drink a decaf pumpkin spice latte late in the day and feel fine, while others still notice it if they are extra responsive to caffeine.

So if your goal is “as low as I can get without giving up the flavor,” a short or tall hot order is the safest bet. If your goal is “I want the biggest drink but still low caffeine,” even a venti decaf version stays light next to standard coffee drinks.

What Changes The Count In Your Cup

Size is only one part of the story. The real driver is how many decaf espresso shots end up in the cup. That is why the jump from one size to another is not always neat. Some markets use one pattern for hot drinks and another for iced drinks, so two drinks with the same name can land a little apart.

Milk choice can change calories, fat, and sugar, but it does not swing the caffeine the way espresso does. In the Starbucks sheets, the decaf caffeine numbers stay the same across many milk choices within the same size. So if you switch from dairy to oat or almond, you are changing the body of the drink more than the caffeine.

Your own custom order matters too. Ask for an extra decaf shot and the number goes up. Ask for half-caf and you are no longer in trace-caffeine territory. Ask for no espresso at all and you are leaving latte territory.

Order Build	Decaf Caffeine	What Usually Drives It
Short hot	1.8 mg	Small cup, one decaf shot build
Tall hot	1.8 to 3.6 mg	Still low, with some market-to-market shift
Grande hot	3.6 mg	Larger cup, more espresso in the build
Venti hot	3.6 to 5.4 mg	Biggest hot build, sometimes with more decaf espresso
Tall iced	3.6 mg	Iced latte build starts a bit higher in one sheet
Grande iced	3.6 mg	Middle iced size stays in the low range
Venti iced	5.4 mg	Largest iced build sits at the top of the listed range
Any size with an added decaf shot	Higher than menu baseline	Extra espresso is the main thing that changes the count

Read that table as a range, not a lab promise. Starbucks menus can shift by market, recipe sheet, and season. Even so, the broad pattern stays steady: decaf pumpkin spice latte caffeine stays low, larger builds run a bit higher, and extra shots change the number more than milk swaps do.

Best Order When You Want The Lowest Caffeine

If you want to keep the number as low as you can, order a short or tall hot pumpkin spice latte with decaf espresso and no added shot. That keeps you near the floor shown in the Starbucks sheets. If you want the drink iced, know that the largest iced size can run a bit higher.

This is also where plain math helps. The FDA says up to 400 mg a day is not generally tied to negative effects for most adults. A decaf pumpkin spice latte sits way below that line. Still, that broad daily marker does not settle how your own body reacts at night. Some people can shrug off 5 mg. Some cannot.

Order Move	What Happens To Caffeine	Best Use
Swap regular espresso for decaf	Drops the drink from full coffee range to a few milligrams	Late-day order with coffee flavor still in place
Pick short or tall hot	Keeps you at the low end	Best fit when you want the lightest trace
Pick grande hot	Bumps the count a bit	Good middle ground for a fuller cup
Pick venti hot or venti iced	Moves you to the top of the listed range	Works when volume matters more than the last few milligrams
Add an extra decaf shot	Raises caffeine right away	Skip this if you want the lowest count
Order half-caf	Lands far above a full decaf build	Only for people who still want some lift

Use this checklist when you order:

• Say “decaf,” not “half-caf.”
• Skip the extra shot.
• Go short or tall hot if sleep is the main goal.
• Ask the café to confirm the shot build if you need the exact count.
• If even trace caffeine bothers you, switch to a pumpkin drink with no espresso.

So, how much caffeine is in a decaf pumpkin spice latte? In most Starbucks-style builds, you are looking at a trace amount: usually around 2 to 5 mg, with official menu sheets showing 1.8 mg on the low end and 5.4 mg on the high end. That is low enough for many people who want the taste of fall without much caffeine, but it is not the same thing as zero.
