(translated) Publisher Blurb:
"To produce quality beer (at least from the sanitary point of view ; taste being a real luxury), you need water (the purest possible ; in Wastburg, the least dirty), barley (hops is for aristocracy), some hardware and a good distribution network. [...] Once brewed, it must be delivered and drunk promptly or get spoiled. This assume you have casks, cask deposit and refund system, carts, delivery persons to delivery full casks and recover empty ones while the brewers work on the next batch. [...] Unless you heavily invest in a brand new brewery and aim for the high end, it is a risky enterprise, and a market hard to conquer. Even more when an old house alread holds it all."
