The secret to a relaxing brew session is to have things organized and have things that run unattended.
Lets break this down a bit. The brewing process consists of getting stuff out, mashing, sparging, boiling, chilling, pitching and cleaning up.
Getting stuff out is self explanitory except that if you aren't organized you will be continually getting things from the kitchen/garage/basement, which can take a tremendous amount of time and energy. I've got everything I need in 1 Rubbermaid container. 1 trip for that plus my pot, cooler and pressure caner and I'm ready to go.
Mashing is pretty simple. Grains pre ground, water up to temp. Mix and let it sit. Go watch a movie. Pretty darn easy ! Check every 20 minutes (on the commercials) for heat loss. With the steam system, open the valve and stir a bit to bring up the temp.
At this point I haven't broken a sweat yet. I haven't really been brewing, I've been watching a movie why the grains soak.
Sparging is pretty simple too. Add water, recirc until clear and then slowly drain. Top up with water once in a while ! I weigh out my hops and start my yeast during this time. This is the first part of the brew session that I actually consider that I am doing something.
The boil. The key to a relaxing boil is to get the heat source set so that it boils unattended. I use a digital thermometer during my boil. A pot at less than 92C needs no attention other than a stir from time to time. During this time I weigh out the hops and clean up the HLT.
From 92 to 95C, I watch a little closer. Wort boils at 96C where I live (3500 feet), so I watch closely from 95 to 96C until its at full boil. A boil over won't occur until 97C, so I watch my temp closely and get the stove set so it holds 96C all the time. If I stir and the temp drops I leave the stove set right where it was because it will bring it right back to full boil, but not boil over.
While the boil is going on, I clean out the mash vessel. Thats the most work of the whole boil. Then I sanitize the fermentation vessel. I'm done with the MLT and HLT at this time so I put them away.
Now its time to chill. If I'm brewing in the kitchen, I have to stir. If I'm using the CFC, all I have to do is watch the outlet temp a bit. Once I get the flow set, its hands off too.
My brew sessions are pretty relaxing and they will be even more relaxing when I get some of my automation projects done.
It really helps to have a sink right in the brewing room. Saves many steps running for water, etc. I'll be putting a sink in the garage with freeze proof faucets in our next house.
Another thing that makes it more relaxing is to have a nice comfy chair and a TV nearby. I found that I tended to do a lot of nervous nelly hovering in my early batches. Now I set things up (mash, sparge, boil, chilling) and leave them run. I'm either getting ready for the next step, cleaning up or relaxing while this stuff is going on. There is no need to hover.
I'm sure you will get much, much better as time goes on. I remember being totally played out with my first batches too. Now I tend to brew on nights when there is a good hockey game or movie on TV so that I am not bored. Like anything, it takes practice.
