Espresso, Black or Iced Coffee for productivity boost?

From friendly social catchups, business meetings, to a caffeinated boost during the day, many of us cannot live without a cup of coffee…

Coffee, consumed by millions around the world, plays a vital role in our society. But with all its variations, which type of coffee is scientifically the best?

Experts at BrewSmartly.com conducted a study investigating which popular coffee drinks boost productivity the most. The study surveyed and grouped 4,250 volunteers and asked participants to complete short tasks before consumption of a specific coffee type (15 in total) and after.

In first place is espresso – this coffee resulted in a whopping 80% increase in productivity as participants completed an average of five of ten tasks before the shot was drunk and nine of ten tasks once consumed.

In second place is the black coffee in a regular-sized cup with volunteers recording a productivity increase of 75% – they completed four tasks before drinking the beverage and seven afterwards. Iced coffee ranks in third place as participants demonstrated a 67% increase in productivity.

On the other hand, drinking a frappuccino results in the least increase in productivity – 14%. Participants scored an average of seven out of ten tasks before and eight out of ten tasks after.

Irish coffees place in second position with a 17% increase in productivity (six tasks before and seven tasks after). Also reporting a mere 17% increase is the cappuccino.

In third place, is the café au lait with a 25% increase in productivity. Not to be confused with a flat white, café au lait is assembled with dark coffee and hot milk. Whereas a flat white, which fared better results in productivity with an increase of 33%, is an espresso with hot milk.


Methodology: For the testing, BrewSmartly.com created different segments of data entry, to see how many tasks volunteers could complete in the one-hour time slot. They then grouped 4,250 participants and gave them ten data entry tasks in a bid to see how many tasks they could fulfil before coffee was consumed, to calculate their average productivity level.

Participants were asked to do the same with different tasks once they had drunk their specific coffee type. All variables were kept the same, such as coffee type, milk, sugar, flavouring and temperature. BrewSmartly then collected the results from the 15 coffee variations and scores were averaged and calculated.
