The double shot may become redundant after scientists work out a way to make even the smallest caffeine hit last all day.

In Switzerland, scientists are working on a new way to drink coffee that will soften that initial kick, but also prevent the afternoon slump so familiar with fans of the dark brew.

They plan to create liquids that mimic the cellular structure of cubsomes (bulk and dispersed cubic liquid crystalline phases), which are naturally in the body’s cells. The cellular structure of the liquid affects the way that nutrients, drugs and stimulants, are released into the body. So, they could create a liquid that slowing releases caffeine over a period of a few hours.

It’s a technology already used by the pharmaceutical company, think slow-release pain medication. The break-through is a new 3D-mapping tool which allows allows for a greater application of the science.

Nestle is pioneering the research efforts, and hasn’t said much about its plans for the technology, except for the following cryptic website update:

“Many of us are familiar with the jittery feeling that comes from consuming too much caffeine too quickly. But what if you could drink one beverage and enjoy the boost effect caffeine provides in a slow, sustained way throughout the day?”

All-day espresso hit? Yes please.
