A survey of European workers has revealed that workplace coffee drinking habits are shaped by time, taste, and the desire for a productivity boost.

The survey, commissioned by the Institute for Scientific Information on Coffee (ISIC) and conducted by YouGov, had more than 8,000 respondents from six European countries, including the UK. Workers were asked about their coffee consumption during the working day to understand when and why they chose to drink coffee, and whether they felt it was linked to productivity.

Across all countries, 68 percent of respondents said they always or often drink coffee during the working day. The top reasons for drinking coffee during work were: liking the taste (56 percent); to have time to pause and rest while drinking or preparing coffee (40 percent); and to feel more alert or less tired (both 29 percent).

However, just over a quarter (29 percent) said that they didn’t drink coffee because they didn’t have time or were too busy to drink coffee at work. Given that those who drank coffee did so for pleasure, relaxation, or to feel more alert, this could be an indication that some people are missing out on these elements because of their workload. In total, around one in 10 respondents (11 percent) said they never took a short break at work to eat or drink something during the working day.

Across every country ISIC surveyed, on average, coffee was the drink most closely associated with productivity, with 43 percent saying it improved their productivity over other caffeinated and non-caffeinated options. Overall, 63 percent of respondents selected short breaks as being most likely to improve their work productivity. Across all countries, 56 percent said they take one to two short breaks per day to have something to eat or drink; while almost a quarter (23 percent) said they take three to four short snack/drink breaks.

Those who drink coffee during working hours are most likely to drink coffee between 9-11am (59 percent) – with the exception of Finland, where workers prefer to drink coffee between 1-3pm (57 percent). Across all countries surveyed, however, there was a clear pattern of coffee consumption: peaking in the morning, with a slight rise at lunchtime (1-3pm), and then becoming increasingly lower during the rest of the afternoon.

A significant proportion (56percent) of people who drank coffee on their commute to work said that it helped wake them up, and more than a third (36 percent) said it helped them feel more alert. There is a recognized scientific connection between caffeine and performance: the European Food Safety Authority (EFSA) has stated that a cause and effect relationship between improved alertness and attention and 75mg caffeine (the amount in a regular cup of coffee) had been established.

ISIC hosted a roundtable discussion into the survey findings, with panelists Peter Rogers, professor of biological psychology, University of Bristol, UK; and Keith Wesnes, professor of cognitive neuroscience, University of Exeter, UK.

“Coffee’s often associated with the workplace, whether that’s in an office setting or on the factory floor. We wanted to understand more about workers’ relationship with coffee, given that there is some very interesting scientific research looking as the associations between caffeine, cognitive function, alertness and concentration,” said Roel Vaessen, Secretary General of ISIC.

ISIC’s survey results include some potentially interesting implications for workplace productivity. OECD data has shown that longer hours are not correlated with improved productivity, hence the number of survey respondents who claim they have no time for a break or a coffee may actually be less productive than their peers.

“ISIC’s survey results have some interesting implications for workplace wellbeing. For example, the fact that that nearly a third of those surveyed cannot find time for a short break could indicate that they have little job control, placing them under stress,” said James Chandler, policy analyst at the Work Foundation.
