If you are the lucky owner of Farm Manager 2021, you must have seen an update of around 450MB a few days ago. This update is just a free DLC that adds beer and wine.
It was sold for € 3,99 when it was released on Farm Manager 2018, this time the Brewing & Winemaking DLC is free and installs itself on Farm Manager 2021. If you were going around in circles on your part, but that we very much doubt, you will be able to diversify. So try hops or grapes as new crops. Harvest and harvest your grapes, since unlike Farming Simulator, you will be able to produce alcohol well. 6 varieties of hops, 7 types of malt, and 11 of vines will vary the recipes. On the machine side, 2 new machines, a harvester and a harvester, will keep your employees busy. New buildings, a cellar and a brewery will serve as warehouses.
If the Steam update has not passed, you can go to the DLC sheet to force its installation.
