WineSearcher is a price comparison channel for wine. Obviously while WineSearcher is not applicable to every merchant, it is a great channel to list your products if you sell alcohol including wine, beer, and spirits.
The WineSearcher Feed Specs don’t have too many field requirements, but you should definitely include the name of the wine, the bottle size, and price. Adding extra descriptive modifiers will of course help improve your relevancy and yield better results on WineSeacher.
