Chokkino contains about 11 mg of caffeine
One espresso coffee contains about 80 mg of caffeine

The daily caffeine limits recommended by EFSA are:
adults 400 mg
pregnant women 200 mg
children 3 mg/kg

So if Chokkino were the only source of caffeine in the day, it would be possible to drink it:
adults 36 cups
pregnant women 18 cups
Clearly we advise against drinking all these cups of Chokkino
