Naked Wines is an online retailer for wine. Visitors to the website can buy one or more bottles of wine or a monthly subscription. The $40 monthly subscription fee goes directly to new winemakers, and the customer receives a $40 credit for wine. Customers buying wine are essentially becoming wine angel investors. The store selections include champagne, white wine, red wine, rose and sparkling.

The fees help self-employed winemakers get started. In turn, members receive free bottle samples and earn a say in how wines should taste (in addition to their store credit). Winemakers take suggestions like “it has too much oak” or “needs more fruit” to heart.
