To upgrade your burgages to level 3 in Manor Lords, you need a tavern that is stocked with Ale. However, there is no dedicated building that creates this resource, so how do you make it.
You need to create a brewery, and to do this, you need to create an extension on a level 2 burgage.
If you don’t know how to create an extension, this guide will explain the whole process. Briefly, you need to create a burgage plot with a big enough backyard to allow an extension. You’ll then need to upgrade the burgage to level 2. Finally, you can create the brewery extension. Note that this will lock the family into the artisan profession, and they’ll be unavailable for general labor.
Once you have the brewery, you need malt to make ale. Malt is made from barley, which is grown in a field. Once you have the barley, you’ll need to build and staff a malthouse to create the malt. Malt will then be taken to the brewery to create ale, and then it will be transferred to the tavern.
A steady supply of ale can be difficult to achieve. The way that Manor Lords is now, you need to grow a lot of barley in order to create malt. Because of this, you may want to use a trading post to either bring more barley or malt into your settlement, thus keeping your supply chain stocked and the ale flowing.
