As you already stated, more content - less ads. currently your site looks like a mix and match of billboards, i don't think you actually need to lessen the ads, you should incorporate the ads into your articles, thus generating content through/via the ads. For one, it would give you immediate ideas about content, for another you'd be tying your advertisers into your reports. Hyperlink to the ads, and drop the skyscraper, billboard, etc. approach, it's almost too antique. If you have traffic, sell banner space (through cpm pricing) that goes userdriven, "adjuggler" is a nifty program that can help with that.
Beef up the content with wine reviews from users, wineries, high level liqueur stores, etc. Give your users a reason to return, by adding userdriven functions to it as in: User recommendations, how to make your own wine in small quantities, etc.
Focus on who you are making the page for then deliver to what your users would like to see and educate them through their own contributions.
Also, Austria (as one of the most award winning countries in terms of white wine production) Italy, France, Australia and some areas in the USA would be thrilled if people came to see them, so far you're linking to other pages. Start coming up with researched content yourself and own your site. Then start recommending places and let your users recommend destinations, which in the end will bring you to a Forum and eventually blog where users can connect AND where wineries can connect with the users.
The page(s) themselves are "ok" for the beginning, you have a lot of work to do. I simply base this statement on: If you're catering to the wine drinker that drinks wine from a paper carton then you're on the right track, your target group though, especially when you present foreign destinations, are people that drink wine from glass bottles, review their peer opinions about products, etc. In short, you're dealing with mostly educated users, approach them as such, visually as well as through your content.
You delivered a good start, all thats left to do is tune it.
just my .02 cents though
