RTD means ready to drink: coffee packaged for consumption without a fresh brewing step at the point of use. The category includes very different products, from unsweetened black coffee to milk drinks and sweetened blends. CoffeeBox's guide considers how origin information and more deliberate flavour positioning have broadened the category beyond a single familiar canned-coffee style.
Read ingredients, serving size, storage conditions and the best-before guidance alongside words such as specialty or cold brew. Cold brew is a preparation description, not a guarantee of lower caffeine or superior quality. Processing and packaging also influence how a product is stored, so a refrigerated item should not be treated like a shelf-stable can.
Choose according to the occasion and actual taste rather than expecting packaged coffee to reproduce every feature of a freshly ground pour-over. Packaging comparisons need local recycling access and production context before supporting environmental claims. This overview explains the category and buying questions without presenting a current market ranking, independent shelf-life test or universal flavour advantage.

A good question can make a better brew.
