I am sure there will be better wine ID/catalog apps, but Delectable is top dog at the moment. The label recognition capabilities are not perfect, but very close. The "expert/industry" ratings are from truly knowledgeable soms, winemakers and vineyard owners. I appreciate that the "buy this" component isnt in-your-face, because that isnt of interest to me, really. My favorite part is the cataloging of the wines by region, varietal and vintage. Very handy.
