Breweries, Malthouse, Barrels and Recipes to make Beer.

First recipes and malthouse and breweries for beer have to be researched.
For example for beer is needed yeast, hops, malt and water.
Malt and hops are brought from the malthouse and the hopsfarm to
a brewery where theyre mixed with water and yeast to make beer.
For classic barrels wood and for metal barrels steel is needed.
After a few ingame-weeks the beer is ready and can be filled into the barrels,
and finally it can be delivered to the foodmarket.

I want a recipe to make Rootbeer.
