Trouble Brewin'

Trouble Brewin' is a quest that can be obtained in the Commonwealth in Fallout 4.

Synopsis
No matter the state of the world, alcohol will always remain a valuable commodity, and in the Commonwealth, there is no exception to this rule. As it so happens, the Commonwealth holds a secret involving a portable brewery from before the Great War, and a certain party is looking to discover this long buried secret.

Walkthrough

 * 1) Rufus Rubins from the Hotel Rexford, will ask for the Sole Survivor to recover some pre-War tech at The Shamrock Taphouse.
 * 2) Upon reaching the cellar of the taphouse, it is discovered that this technology is a micro-brewery that has been jury-rigged onto the body of a protectron.
 * 3) At this point, the portable brewery, designated the Drinkin' Buddy, may be optionally kept as a companion of sorts. However, it can only be sent to a settlement of the Sole Survivor's choosing, and will not actually provide company any further in the Commonwealth.
 * 4) Whichever choice is made, Drinkin' Buddy, at any given time, can be instructed to head off to the Hotel Rexford, in which Fred will reward the Sole Survivor upon arrival.
