The men, aged 25-28, were part of a group of 12 heading to to Bratislava from London on Friday evening.
Reports say they became unruly and the plane was forced to carry out an unscheduled landing. German police officers met the flight.
The bridegroom was among those detained, officers said. The other six members of the stag group continued their journey.
German federal police in Berlin said in a statement that six members of the group, from Southampton, were threatening the security on board and did not comply with the crew's instructions.
They reportedly became aggressive when the crew refused to serve them any more alcoholic drinks, the BBC reported.
Police officers at Berlin's Schoenefeld airport charged the men with misdemeanours under the German aviation security laws, which can be punishable by a fine of up to 25,000 euros (20,000 pounds), they said.
A possible civil damages suit from the airline could also follow.
The men have now been released, the report said.
