Black coffee has zero sugar; the sugar comes from syrups, sauces, and sweetened milk.
Blended and flavored coffee drinks can carry 40–70g of added sugar.
Cutting pumps of syrup and choosing unsweetened milk dramatically lowers sugar.
Coffee itself is one of the lowest-calorie drinks there is — plain brewed coffee has essentially zero sugar and about 5 calories. Everything sweet in a coffeehouse drink is added. Here's where it comes from.
Where the sugar hides
The sugar in a coffee drink comes from a few sources:
Flavored syrups: each pump adds roughly 5 grams of sugar. A large flavored latte might have four pumps — 20 grams before anything else.
Sauces (mocha, caramel, white chocolate): sweeter and often higher in sugar and fat than syrups.
Sweetened milks and creamers: oat milk and sweetened condensed milk add sugar; whole dairy adds natural lactose.
Toppings: whipped cream, caramel drizzle, and cold foam pile on more.
Typical amounts
A plain latte has only the natural sugar from milk (around 12–18g, none added). But a large caramel or mocha blended drink can reach 50–70 grams of added sugar — meeting or exceeding a full day's 50-gram budget in one cup. Seasonal specialty drinks are often the sweetest of all.
How to cut it
Small changes add up fast: order fewer syrup pumps (or ask for sugar-free syrup), skip the sauce and whipped cream, and choose an unsweetened milk. Sizing down helps too, since syrup scales with size. Black coffee, espresso, and unsweetened lattes give you the coffee without the sugar load.
Build your usual coffee order in the BevFacts app, adjust the syrup pumps and sweetness, and watch the added sugars line rise and fall in real time.
Frequently asked questions
Does black coffee have sugar?

How much sugar is in a flavored latte?
It varies, but a large flavored or blended coffee drink can contain 40–70 grams of added sugar. Each pump of flavored syrup adds about 5 grams, and sauces and toppings add more.
