Slow Spirit Run

A few days ago I did my first long and slow run (approx 16 hour). I couldn't believe my eyes when looking at the reading... hour, after hour at the same high mark on the meter. :D Wow, much different experience than running quick at 1300W for the low wines.

Before this, I did quick stripping of multiple sugar washes to low wines and ended up with 16L at 40% (with cuts made). To the low wines, I added baking soda (bicarbonate) and let it sit for a few months.

For the slow run, I took the 16L of low wines, and added 4L of tapwater to refresh the mix and keep it under 40%, and act as a sort of buffer.

My setup:
- 2-inch diameter column Bokabob (similar to Pikluk's, with old design placement of thermometer below plates)
- one-and a half-times, 1/4 inch copper coil wrapped condenser that drops in the top of the column
- Brewhaus Stainless Kettle and fittings (kettle insulated with aluminum windshield reflector and bungee cord)
- Waring Pro Hot Plate (1300W)
- Dimmer Switch (rated for 1500W) to control hotplate temperature-cycling (butchered an extension cord- to work with hotplate and dimmer)
- Pond pump with tubing to condenser
- cooling water reservoir (bathtub)
- 2 digital thermometers (one under collection plate, one at top of column)
- Parrot w/ proof and traille hydrometer (alcoholometer)
- Stainless steel funnel
- Stainless Steel Scrubbers (column packing, and to loosely cover the top of condenser)
- various labelled glass containers

After about 110ml/210ml of of foreshot/heads removed, I collected a little over 5L at 95%. I could have collected the last bit and the tails, but at that point was getting tired, and decided I had enough and shut it down.

Next batch, I'll reflux a bit less and increase output rate, and compare the 'taste.'

I let everything air out for a day. I used freshly made distilled water (from a home appliance)...and then filtered the distilled water through a Brita filter. Never needed any carbon for the spirits though. :)

Then I diluted to 42% as per the calculator on the site.
End Result: Remarkable! Smooth, silky and perfect. No off-taste at all.

Perfect.
Parrot setup with proof and traille hydrometer... and some creativity.

I hear ya on the slow spirit runs... my run took around 20 hours and I ended up collecting over 5 gallons of 95%.

I have GOT to find a faster rig.

20 hours for 5 gallons@ 95%... How did you stay up? No way I could stay awake past 16 hours. On this run near the end, as soon as I felt my eyes closing for a few seconds and want to stay that way, I shut everything down.

That is the fine line eh... finding a rig the is suitable to your required volume, environment, budget, and time limitations.

I usually set my rig up and let it get to boiling, which takes around 2 hours with a 1500W element. Then I get it running and as soon as the heads pass I start collecting in gallon jars. Then I pretty much walk away and leave it be... if I need to nap I set my 120db truck driver alarm clock in countdown mode and go to bed.

Yeah yeah I know your not supposed to leave a still unattended, but I am confident in my rig enough to leave it alone for an hour or so at a time.

With a reflux column, once you are out of the heads and into the hearts, you can stop and restart the run anytime you want, without having to re-equilibrate for an hour, jut ten minutes is usually enough. I often do my neutral runs over 2 or even 3 days. First day set up and take off the fores and heads real slow, and maybe start the hearts section. Second day continue the hearts, and if I do not have enough time, I shut down, and finish them off on the third day. Usually only takes 2 days though.
