Run Procedure iStill One: Stripping a Clear Wash

03 December 2014
Hi there, here's another run procedure for the iStill One. Required reading for iStill One owners or will-be iStill One owners. The procedure is for the iStill One doing a strip run, to take a mash of 7 to 12% and turn it into 30 to 40% low wines for a brandy, rum or whiskey. For beer or wine stripping, so without (many) solids in the liquid you are going to strip. Stripping run approach on a clear wash:
  1. Take away all cleaning sections;
  2. Empty the iCatalyst by taking out the copper packing - place the packing under 45% strong alcohol to prevent copper corrosion;
  3. Place the 180 degree bend (from column to product cooler) directly on top of the now empty catalyst;
  4. Dial in the end cut point into the computer: 99.5 degrees C boiler temperature;
  5. Fill to boiler with a maximum of 1,250 liters of wash;
  6. Set the agitator at 5 revs per minute;
  7. Open up the water cooling;
  8. Fire up the heaters at full power;
  9. The boiler content will heat up in two hours;
  10. You will see the first drips coming off as soon as 65 degrees C (output temperature) is reached;
  11. Keep throwing 100% power at the iStill One during the entire run;
  12. Collect everything in your low wines container until the computer alarm for 99.5 degrees C in the boiler goes of;
  13. Now stop the program on the computer and shut down the agitator;
  14. Then shut off the gas burners;
  15. Keep the cooling water flowing for at least another 30 minutes, while the iStill One collects some additional low wines automatically, even with the burners off.
You can do multiple strip runs and combine the low wines to do a finishing run on (keep total ABV in the boiler at a maximum of 30%). Or you can dilute the low wines with fresh wash and do a finishing run on that. For the finishing run, please see the previous Blog Post.
