THE NUMBERS
Brewed coffee nutrition facts per 100 g
The table below uses the reference state shown at the top of this page. Keeping one gram basis makes it easier to compare foods before translating the values to the portion you actually ate.

SERVING SIZE
Calories by portion and serving weight
Words such as “small,” “medium,” “half” and “one piece” are convenient but imprecise. Grams make the estimate reproducible, particularly when natural foods vary in size.

FOOD STATE MATTERS
How preparation changes the nutrition estimate
A reliable calorie entry should describe the food you actually ate—not merely a food with a similar name.
Brewed with water
Selected generic reference.
Decaffeinated
Mapped separately from regular brewed coffee.
Espresso or instant
Use the preparation-specific record.
Milk-based or sweetened
Log milk, cream, syrup and sugar or use the complete product label.
PRACTICAL CONTEXT
How brewed coffee can fit different goals
There is no universal “good” or “bad” food. Portion, frequency, the rest of the meal, preferences and individual health needs all matter.
Portion math
At 1 kcal per 100 g, the 29.6 g example is 0.3 kcal.
Fibre check
The selected record lists 0 g fibre per 100 g.
Protein check
The selected record lists 0.12 g protein per 100 g.
Best logging move
Measure the brewed coffee and record every milk, creamer, sugar or syrup separately.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Use clean brewing equipment and potable water.
After opening or cutting
Follow equipment and manufacturer handling directions.
Prepare
Treat milk- or cream-containing coffee according to the added dairy product's guidance.
Safety boundary
The nutrient record does not establish caffeine advice, hot-drink safety or storage duration; use current authoritative guidance.
PHOTO LOGGING
How to log brewed coffee more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Beverages, coffee, brewed, prepared with tap water.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
