Bottling 5 gallons? About 45 minutes...an hour max...
You just gotta dial in your process,....try different things until they work for you, until you've pimped it down to the bare minimum of steps...and practice practice practice...and if it doesn't work for you, then scrap it and change it again...
For example I hated the bottling wand on the end of a hose, with the bottles in beer case method, that most people use..You know, then one shown in Papazian's book where the bucket is on the counter and you sit on the floor and fill the bottles sitting in the cases....well the first time I did that, I lost track of where I was in order, and actually capped about a half dozen empty bottles...as well as spilling a sh*tload of beer because I could really see when the wand was putting the beer to the lip of the bottle....a ton would spill out....
Plus sitting for so long on the floor was bad for my back....
So I kept tweaking my process until I was happy...
I start my priming sugar water boiling before I start sanitizing my bottles with my vinator....after the first case is sanitzed then take it off the stove to let it cool a bit.
I have my bottling wand mounted right on my bucket's spigot...
So I can sit at my dining room table and fill bottles confortably...I prop my bucket on a pot, or fermenter bucket to bring it up to my eye level.
I have a dip tube in my bucket so I get all but about 4 ounces of stuff from my bottling bucket.
Since I'm a lefty I work right to left on my table....I put my two cases of sanitized bottles on the right hand side of the table (on the chair next to me,) I put the vinator on the table to the right of the bucket filled with my bottles caps sanitizing away. then when I fill the bottle I place a cap loosely on it, and move it to the left side of the table...with the bottling bucket in the middle of the table there's room for a case worth of filled bottles on the table on the left side.
When I hit 24 bottles, I stand up, move the empty case to a chair on the left side of the table, then I pick up my capper and cap the first case of bottles, putting them in the case on the chair nearby...Then I grab a beer from the fridge, and sit back down and do the next case of beer....
I can get them all done and the bottling bucket and stuff soaking in oxyclean between 45 minutes and an hour....
I usually start a basic brewing podcast then get started..and I usually hit the end when I'm done bottling.
