Constellation Brands has announced that the president and CEO of its Constellation Services business, Andy Berk, is to retire.

Berk, who is also a member of the California wine giant's executive management committee, will stand down on 31 May, Constellation said late last week.

Constellation Services provides support services to Crown Imports, Constellation's US joint venture with Mexico-based Grupo Modelo.

Berk will remain as a consultant for one year and continue to serve on Crown Imports' board of directors, Constellation said.

Following Berk's departure, the Constellation Services management team will report to Constellation's executive board.

Berk joined beer group Barton Incorporated in 1990 as president and chief operating officer, and continued in that role after Barton merged with Constellation Brands in 1993. He was named president and CEO of Barton Incorporated in 1998 and appointed CEO of Constellation Beers and Spirits in 2003.
