It is the first move by Baarsma into the UK market and the company said it intended to make other acquisitions in the future.
Cees de Rade, Baarsma’s chief operating officer, said: “We regard it as our first step into the UK.”
The current Armit management will remain with the company.
“The team is very professional and motivated and the company offers many synergy possibilities within the Baarsma group,” said de Rade. “Armit also enhances our position in the higher wine segment.”
Baarsma has a declared policy of international expansion by acquisition in north west Europe.
It bought the Cellarmaster Wines Europe mail order business last year, and the Canei Italian wine brand from Pernod Ricard.
It has wine trading operations in France, Switzerland and South Africa, and is the Dutch distributor for Constellation brands.
Armit was founded by John Armit in 1988 and has earned a glowing reputation for taking a modern approach to traditional fine wine trading.
It claims to be one of the UK’s biggest importers of first growth Bordeaux and is the exclusive agent for leading Pomerol house Chateau Lafleur.
Its Italian agencies include Sassicaia and Angelo Gaja.
Armit chief executive Ian Ronald said: “This will enable the company to realise its ambitious growth plans, with preservation of our service, customer orientation and traditions.”
