Did you know whisky matures in the most unexpected places?

Never miss whisky news, reviews, and new releases again.

What would happen if a whisky cask matured not on Earth, but in space? It might sound like science fiction, but scientists are set to investigate the effect of space on whisky maturation. Under the name Project Space Puffin, the University of Glasgow and Japan’s Kyushu Institute of Technology are joining forces for a remarkable experiment. But what exactly are they hoping to discover?

Why mature whisky in space?

Several chemical processes play an important role in whisky maturation. This experiment will focus in particular on cycles of heat and cold. Rapid temperature fluctuations may speed up certain processes that take place as whisky matures.

The team is developing a small satellite carrying experimental materials and equipment. Using it, the researchers hope to study what happens under the conditions of Earth orbit. Wood, of course, plays an essential role in whisky maturation. The interaction between the spirit and the wood accounts for around 70 to 80% of the aromas, colours and flavours of the finished product.

But what happens when you change those conditions?

Did you know whisky can mature on the seabed, too?

Distillers have been experimenting for years with exposing wooden casks to all kinds of conditions.

Take the practice of placing casks on the seabed, for example, as French producer Maison Benjamin Kuentz has done. Whisky is also being put to the test in Scandinavia, where it matures in extreme climatic conditions. Another well-known example is the Jefferson’s Ocean range. Its bourbon casks embark on months-long sea voyages to explore how temperature and environmental factors, such as salty sea air, affect maturation.

So distillers’ ongoing search for new ways to influence maturation is nothing new. But sending whisky into space takes things to a whole new level.

When will the whisky go into space?

Back to Project Space Puffin. The team aims to launch a CubeSat in 2028. The small satellite will first travel on a mission to the International Space Station (ISS). From the station’s Japanese module, the CubeSat will then be sent into orbit around Earth.

The mission will last up to five years. During that time, the researchers aim to map the chemical processes in detail and discover how the unique conditions in space affect them.

That means it could be as late as 2033 before the full results of the experiment are known. Who knows what new insights this could offer into whisky’s flavours, aromas and colours? Perhaps one day, lovers of the water of life will be sipping whisky matured in an entirely different way.

Exciting, isn’t it?

FAQ

What is Project Space Puffin?
Space Puffin is a collaboration between the University of Glasgow and Japan’s Kyushu Institute of Technology. The researchers aim to discover how conditions in space affect the chemical processes involved in whisky maturation.
Why are scientists studying whisky maturation in space?
The researchers are focusing in particular on the effects of rapid temperature changes. These may speed up certain chemical processes during maturation.
When will the results of Project Space Puffin be available?
The CubeSat is scheduled to launch in 2028. The mission could last up to five years, so the full results may not be available until 2033.
