Slow Spirit Run
Posted: Mon Nov 02, 2009 11:05 am
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.
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.
