U.S. Coffee Habits: What They Do—and Do Not—Tell Us About RTD Demand
U.S. coffee surveys show strong habits, but packaged RTD coffee is a narrower market. Compare NCA drinking data with channel-specific retail sales before making a buying decision.

Americans drink a great deal of coffee. That makes the United States an important market to study, but it does not automatically make every ready-to-drink (RTD) coffee a promising retail opportunity. A survey about cups consumed answers a different question from a scanner report about cans and bottles sold. For beverage buyers, the useful task is to connect these two kinds of evidence without treating them as interchangeable.
In September 2026, the National Coffee Association (NCA) reported that 66% of U.S. adults drank coffee in the previous day. It also found more cold-coffee occasions during summer. Those findings describe consumer habits, not packaged-coffee sales forecasts. Retail tracking provides a closer view of purchases, but published figures vary by channel, storage conditions and product classification.
Define the category before reading the numbers
RTD coffee is a finished coffee beverage sold ready to drink, commonly in a can or bottle. It can be black, milk-based, sweetened or flavored. The definition concerns the final packaged product. An iced latte prepared in a café and a refrigerated bottled latte may taste similar while belonging to different retail channels. Cold brew can be prepared at home, ordered at a café or sold in a sealed package. Neither cold nor specialty automatically means RTD.
Our consumer evidence comes from the NCA's publicly released National Coffee Data Trends (NCDT) highlights. The Spring 2026 survey covered 1,850 adults in January, and the Fall 2026 survey covered 1,882 in June. Both samples were described as nationally representative of Americans aged 18 and over, all having consumed a beverage other than tap water the previous day. The complete paid report and respondent-level data were not reviewed. See the spring release and fall release.
1. Coffee has broad reach, but this is not an RTD penetration rate
The NCA reported 66% past-day coffee consumption in both 2026 releases. Coffee is clearly part of many Americans' routines. Yet 66% does not mean that 66% of adults buy RTD coffee. The measure includes coffee from kitchen brewers, restaurants, cafés and packaged products. Nor does this figure demonstrate a rise in overall daily participation between those two surveys.
The fall release reports that 47% of adults had an espresso-based beverage in the previous week. This can inform hypotheses about familiar latte or mocha flavors. It cannot establish that a sealed version will win a shelf. Price, sweetness, packaging, placement and repeat purchase still determine the outcome. familiarity can reduce the burden of explaining a concept. conversion from a general coffee habit to a specific RTD SKU.

2. Home and out-of-home consumption describe occasions, not packages
In June 2026, 83% of past-day coffee drinkers had coffee at home and 38% consumed coffee away from home, according to the NCA. These groups overlap. A person might make one cup at home and purchase another on the way to work, so the percentages should never be added together.
Home drinking can involve ground coffee, pods, instant products or RTD beverages. Out-of-home drinking may involve freshly prepared coffee, not a packaged item. The same NCA release says 55% of past-week out-of-home coffee buyers used a drive-through and 40% ordered through an app. Those are behaviors within the out-of-home buyer group, not shares of all American adults. Interpretation: convenience and routine deserve consideration. Unproven: how many such occasions are available to bottled or canned coffee.
3. Cold-coffee interest is real, but not all cold coffee is packaged
The NCA's Fall 2026 release says 21% of past-day coffee drinkers had cold coffee in the June survey, versus 17% in January. Hot coffee accounted for 71% in June and 78% in January, using the report's stated measure. The publisher also reports 16% cold-coffee consumption for 2022. Seasonality therefore belongs in an evaluation of sampling and shelf placement.
Still, the cold category includes homemade iced coffee, café espresso poured over ice and packaged cold brew. The broader NCDT specialty definition includes many preparations, as clarified in Daily Coffee News's analysis. Neither summer cold-drink prevalence nor specialty-coffee popularity measures the sales rate of a packaged drink. Hypothesis worth testing: an accessible cold format could fit some warm-weather occasions. The test must identify its actual channel and shoppers.
4. Historical RTD participation is more relevant, but still not sales
The NCA's September 2025 release reported that 19% of past-day coffee drinkers had RTD coffee, compared with 9% in 2021. This consumer measure speaks more directly to packaged coffee than the 66% headline. But it is a historical comparison among coffee drinkers, not a count of units sold, a current 2026 RTD estimate or a brand-loyalty measure.
Without consistently defined RTD survey questions over time and channel-level retail data, it is not responsible to turn that figure into a forecast for a new canned or bottled product. It indicates that RTD is an established reported behavior, not that every formulation will find commercial demand.
5. Retail figures tell a more complicated story
Dairy Foods reported Circana data for the 52 weeks ending July 13, 2025. Refrigerated RTD coffee recorded about $1.3 billion in dollar sales, up 7%, while unit sales increased 5%. In a separately defined RTD cappuccino/iced-coffee segment, dollar sales were approximately $3.3 billion, down 6%, and units declined 8%.
These are distinct subcategories. They should not be combined into a purported total RTD market without checking the research provider's taxonomy, tracked channels and overlap. A drop in units alongside more dollars could also reflect pricing rather than more purchasing occasions.
A 2026 Beverage Industry analysis cites another Circana period: 52 weeks ending April 19, 2026, across U.S. multi-outlets including convenience stores. It reports refrigerated coffee at about $1.3 billion, with dollar sales up 4.6%. Its $19.2 billion figure for all coffee includes many non-RTD formats such as ground and single-cup coffee. It is not an RTD market-size estimate.
The 2025 and 2026 periods have different end dates. Nor does the public reporting prove identical category definitions and channel coverage. Avoid calculating a new growth rate by directly comparing their dollar totals. Interpretation: packaged-coffee performance differs by segment and retail context. Still needed: a consistent, current dataset showing units, distribution, prices and repeat purchasing for comparable products.
A buyer's evidence ladder
Different questions need different measurements. A survey may justify exploring a flavor. Actual store velocity and repeat purchase are more relevant to expanding distribution. Before citing any market statistic, record its date, geography, respondent or store universe, category definition and measurement unit.

How to test a concept without overstating demand
Start with a defined product and shopper. A black canned coffee for convenience-store commuters faces different substitutes from a sweetened milk latte in a supermarket refrigerator. Identify the exact format, serving size, caffeine positioning, intended temperature and target retail price. Compare competitors with similar characteristics, including freshly prepared coffee where relevant.
For a controlled test, request weekly units per store, points of distribution, shelf availability, realized selling price and promotional periods. Measure trial separately from repeat purchasing where retailer or shopper-panel data make that possible. Review margin after freight, discounts and other channel costs. A successful small pilot could support wider testing, but it does not automatically represent the entire U.S. market.
Ask the retailer how it categorizes and merchandises the SKU. Refrigerated and ambient distribution carry different storage and handling requirements. Confirm the actual product documentation, shelf life and labeling for the destination market rather than transferring specifications from another coffee product. These are due-diligence questions, not claims about any particular Nam Viet product's U.S. eligibility.

The bottom line
America's coffee habit is widespread, and cold-coffee occasions warrant commercial research. But daily consumption, specialty-drink preferences, RTD survey participation and retail scanner sales are different kinds of evidence. The public numbers do not justify treating 66% past-day coffee consumption as demand for any particular can or bottle. Build the case through a defined shopping occasion, comparable products, consistent sales units, distribution and repeat purchase. That is a sounder foundation for a buyer conversation than a broad coffee headline.
Frequently asked questions
Does the 66% daily coffee figure mean 66% of Americans buy RTD coffee?
No. It includes coffee prepared or bought in many forms. Packaged ready-to-drink consumption is a narrower measure and must be identified separately.
Can rising retail dollar sales occur without higher unit sales?
Yes. Prices and product mix affect dollar sales. Compare units, periods, promotion and distribution as well as revenue.
Is all cold brew counted in the retail RTD category?
No. Cold brew can be homemade, freshly served or packaged. Check the specific product and the research provider's category definition.
What should a buyer ask for before expanding an RTD coffee trial?
Weekly units per store, distribution and availability, realized prices, promotion effects, repeat purchase when measurable, and viable margin for the intended channel.
