Keto Coffee and Tea: Net Carbs in 21 Drinks and Add-Ins
Black coffee and plain tea are close to zero carbs: USDA lists 0g for a cup of brewed coffee and 0.7g for a cup of brewed black tea. What goes into the cup decides whether it stays that way.
A tablespoon of heavy cream adds 0.4g. Two tablespoons of half and half add 1.3g, a teaspoon of sugar adds 4.2g, and a sweet cream creamer adds about 5g per tablespoon. Bottled drinks are where the numbers jump: a 13.7 fl oz Starbucks Frappuccino lists 54g of carbohydrate and an 18.5 fl oz Pure Leaf Sweet Tea lists 42g.
Plain drinks and kitchen add-ins come from USDA FoodData Central. Creamers and bottled drinks come from Chobani, Califia Farms and PepsiCo’s product facts site, which lists the bottled Starbucks and Pure Leaf lines. Add-ins are shown per typical pour so you can add them to the drink you make.

Frequently asked questions
Yes. USDA lists 0g of carbohydrate and about 2 calories for an 8 fl oz cup of brewed coffee, and about 0.5g for a 1 fl oz shot of espresso. The carbs come from what you add: sugar is 4.2g per teaspoon.
Heavy cream is the simplest choice at 0.4g of carbs per tablespoon (USDA). Half and half is 1.3g per 2 tablespoons. Among flavored creamers, Chobani Zero Sugar Sweet Cream lists under 1g per tablespoon, while the regular Chobani Sweet Cream lists 5g of added sugar per tablespoon. Most people pour more than one tablespoon, so multiply.
A splash is fine. Two tablespoons of whole milk add about 1.5g of carbs by USDA data. A milk-heavy drink like a latte is a different matter, since a full cup of whole milk carries 11.7g.
The black, unsweetened versions are. Starbucks Cold Brew Black Unsweet and Califia Farms Pure Black Cold Brew each list 2g of carbs per 12 fl oz. Flavored cold brews with sweet cream are not: Starbucks Cold Brew Vanilla Sweet Cream lists 19g per 11 fl oz can.
Regular sweet tea is not. Pure Leaf Sweet Tea lists 42g of carbohydrate, all sugar, per 18.5 fl oz bottle. Pure Leaf Unsweetened Black Tea and Pure Leaf Zero Sugar Sweet Tea both list 0g; the zero sugar version uses sucralose and acesulfame potassium.
No. The 13.7 fl oz Coffee Frappuccino bottle lists 54g of carbohydrate and 47g of sugar, more than two and a half times a strict 20g day. The 9.5 fl oz bottle still lists 38g. For a bottled Starbucks drink, Cold Brew Black Unsweet (2g per 12 fl oz) is the low-carb pick.
