(WineIndustryInsight) - Amazon is getting back into the wine business in time for this year’s holidays, according to Washington State sources close to the mega-online retailer who spoke to Wine Industry Insight on condition of anonymity. Indeed, Napa and Sonoma County vintners who attended meetings this week are non-communicative because of non-disclosure agreements they had to agree to in order to be part of the new Amazon Marketplace for wine. Similar to the existing third-party marketplace for other products (sold and shipped by some 2 million independent vendors) Seattle-area sources tell WII that Amazon wants to have the system for Napa and Sonoma up and running in the next four weeks.
