(Forbes) - Along with bestsellers and electronics, we can now browse the mighty Amazon.com for wine. The online retailer’s entry into the wine marketplace is a solid affirmation that online wine sales are big business, which should be good news for the wine industry. Rich Bergsund, CEO for Wine.com, a leader in online wine sales, believes it’s an exciting time for the wine business. “Amazon entering the online wine sales is a good thing; anything that makes wine more accessible is a good thing.” Access has been a problem, but Bergsund notes that Wine.com’s revenue has doubled in the past 5 years while also cautioning that, “Online wine sales are still a small part of the overall market because of regulatory hurdles.”
