Researchers have warned that coffee in Glasgow is stronger than what is served in Spain and Italy and this could have health implications for people trying to control their caffeine consumption.
The study has suggested that a person cannot place reliance on counting cup numbers when trying to control their consumption.
Coffee may be able to keep tiredness at bay, as well as some disease symptoms, but it also has negative side effects, such as feelings of anxiety. It is recommended that pregnant women not consume in excess of 200mg of caffeine each day.
Following on from a previous study where caffeine levels in coffee in Glasgow were assessed, researchers at the University of Glasgow and scientists in Pamplona, Spain and Parma, Italy tested the strength of more than 100 espressos. They also tested some instant coffees and cappuccinos.
The study concluded that coffee served in Scotland was stronger because heavily-roasted beans were used and customers were provided with bigger servings.
The level of caffeine in an espresso in Glasgow was between 72mg and 212mg, whilst in Italy it was between 73mg and 135mg, and in Spain, between 97mg and 127mg. These figures were compared to an average black filter coffee which has 40mg of caffeine.
Even the cappuccinos in Scotland were stronger and contained between 101mg to 275mg of caffeine in each cup.
Based on these findings, researchers have issued recommendations that consumers should be offered information on the caffeine levels and the bean variety.
