Ok I figured it out so first you need the entegram or blueprint at lvl 36! Then craft it at the smithy aka the smithing table that unlocks at lvl 20 along with the forge, you need the forge to make smithy! Then you need some water pipes and then leme put it this way->YOU NEED TO PLACE THE BEER BARREL ON TOP OF THE WATER PIPE TO GET WATER INSIDE, AND NO YOU CANNOT USE WATERSKINS WITH THE BARREL!!! THEN PUT SOME BERRIES INSIDE IT! IF YOU DONT WANT TO WAIST YOUR BERRIES, THEN USE STEMBERRY OR SOMETHING! THEN WAIT AN HOUR AND YOU HAVE LIQUID BEER! YOU CAN FILL A WATER BOTTLE WITH THE LIQUID BEER TO MAKE BEER that’s in a cup I guess. Make the arrow go towards something above you if this help. By:JUST YOUR FELLOW HELPER

I can get it on mobile but I don’t know how to make beer
