Don’t worry! We are here to answer all your questions and help you make the right decision to save you money and time.

Single-serve Coffee: What’s the Hype?

The hype around single-serve coffee is based on convenience as they exhibit efficient and user-friendly features. Since its initial release, the single-serve brewing systems have seen exponential gains in market share. According to NCA’s National Coffee Drinking Trends report of 2015, 27% of daily coffee drinkers in the U.S use single-cup brewers, making it the second most common preparation method after a traditional drip coffee maker. And their popularity is still astronomically growing, both in-home and at work.

As single-cup evolves from a sensational trend to a developed market, we’re seeing exciting prospects across the segment for innovation, collaboration, and consumer education to change the conversation around single-serve systems.

Single-serving coffee has revolutionized our lifestyles and customs. It has moved espresso out of its conventional places of consumption, much like the invention of the teabag in the 1970s, which overturned the market and consumption habits for this beverage as the system of single-serve coffee in capsules includes the essential requirements for market success providing substantial advantages such as efficient service, high quality, and reliability.

Brewing only one cup at a time means that you’ll also be using less coffee and wasting less coffee, which will ultimately save you money over full brewing pots. If you are substituting the single cup coffee maker for buying your coffee at a coffee shop each morning, you’ll realize even more savings.
