Called Clarity, the magazine will go out to 20,000 consumers who mostly buy wine to drink and 15,000 who mainly buy it for investment or to enjoy it in the future.
Separate editions of the magazine will be tailored to the two audiences. Each edition will be 20 pages long and will be mailed out four times a year.
Clarity will channel the expertise of people who work for Berrys to help customers develop their knowledge of wine.
It will also showcase offers such as sampling cases and services such as Cellar Plan and Wine Club.
David Napier, account director at TMW, said: "The Berry Bros & Rudd brand is very well known and respected among wine enthusiasts.
"The brand has a great story to tell through Clarity. Our aim is to enhance the customer's experience of the brand by putting wine more into context with some seasonal inspiration and interesting content, while providing valuable offers and incentives to drive sales."
TMW has also redesigned a series of email templates which will be used to support the campaign.
The agency was appointed to the account in July 2008.
