Landing pages with different domain

Dear,

I'm developing a beer web shop for the moment, let's simply call it beerwebshop.com. I think I already have your attention

I have translated all productpages and information pages into English, French, Dutch and German, all covered by the same domain name beerwebshop.com. I'm mainly aiming at the following markets : Netherlands, Belgium, Germany, UK and France. In order to do so I'm thinking about buying domain names in those languages. A few examples :

- onlinebeer.co.uk
- koopbieronline.nl
- acheterdelabiere.fr
- biereenligne.fr
- bierkaufen.de
-...

I believe it is no longer beneficial to simply redirect those domain names to my beerwebshop.com site. Therefore I'm thinking about creating landing pages with content about the topic of the concerning domain name. So in this case I would have to write a text in German about 'Bier Kaufen', a text in Dutch about 'Koop bier online'... Here are some questions :

1. Is this a good idea?
2. Is it better to include these text pages into the beerwebshop.com site and then 301 redirect the domain to this page? Or is it better to create an entire new website, only containing these landing pages with matching domain names and then put a link of beerwebshop.com somewhere in the text?
3. What are the consequences for the SEO of my beerwebshop.com pages?
4. Extra tips or a better strategy is always welcome.

Thank you very much in advance and I'm looking forward to the responses.

Cheers
