Good looking site - very clean and easy to navigate through. (I did notice a small typo on your 'products' page) - "provide you with the means to make aroun 50 bottles".
not bad - some errors, though: not all links point to something. For example, all those links in "the process of brewing" section point to empty pages.
I think a forum might be a good thing to have - It might be cool for people to discuss their own advice, tips and tricks, different methods, etc. And those are easy to set up.
