Prime Cellars of Napa is inviting your opinion on two possible labels for their new Chardonnay. It's a fun exercise, so go over and leave your thoughts in the comments.
The best thing to do is print them both out (ideally on label stock), paste them on bottles and go down to the local market (one with lots of bottles on the shelf - e.g. Molsberry Market in Santa Rosa), and see which one stands out the most from the crowd of Chardonnays on display. Don't have an opinion, have data!
And if they truly both suck, start over. The attractiveness and recognition factor of your label is one of the most powerful tools you have to sell your wine.
Just like winery Web sites tend to all have nice pictures of vineyards, most wine labels tend to be remarkably similar-looking.
