First Spirit Run Questions
Posted: Wed May 21, 2014 11:34 pm
Just finished a spirit run for the Gerber recipe. This is my first "real" spirit run. My only previous experience is with fiddling around with Franzia washes, which didn't produce very good results.
The whole process seems to take a looooong time. I'm wondering if I'm doing something wrong. Below is my whole run. Comments on what I could do differently are much appreciated. I think I could have saved about a 1/2 hour by calling it quits after collecting what I calculated to be 68% of the total alcohol. But, I've read on here that things shouldn't really slow down until after collecting about 75%. Also, I topped out at collecting 78% which seems odd.
At any rate, my boiler charge was less than 1.5 gallons @ ~50% and it took over 3 hours. That seems wrong. That would mean a 4 gallon charge @ ~50% would take about 6 hours!
Is that right?
Also, my setup time is about 30 minutes and my tear down time is about 1 hour. How does that compare to other folks'?
And, finally, it was surprising to me that the temp held at 168F for so long, and then later (container 7) dropped back down to 168F. Does this mean that there were a whole bunch of foreshots/heads in the wash?
Charge:
4613.471 ml @ ~ 49.5% (99 proof)
Total ABV: 2283.668145 ml
Run:
~9:30 - Start setup
10:07 - start heating on 10 (heat setting for stove-top element).
10:22 - temp starts rising. lower heat to 3. (T0)
10:24 - temp between 169-171.
10:26 - raise heat to 4.
10:30 - temp between 168-170.
10:32 - temp at 168. start collecting container 1.
10:35 - temp at 169. stop collecting container 1.
10:37 - temp between 171-172.
10:38 - start collecting container 2.
10:41 - stop collecting container 2. temp at 172.
10:43 - temp between 171-172.
10:51 - start collecting container 3. temp at 171.
10:53 - stop collecting container 3. temp at 172.
11:03 - start collecting container 4. temp between 171-172.
11:18 - stop collecting container 4. temp at 172.
11:21 - start collecting container 5. temp at 171.
11:38 - stop collecting container 5. temp at 174.
11:53 - start collecting container 6. temp between 172-173.
12:08 - stop collecting container 6. temp at 175. heat off. heat to 4.
12:23 - start collecting container 7. temp at 168.
12:57 - stop collecting container 7. temp between 170-173.
01:07 - start collecting container 8. temp at 170.
01:14 - stop collecting container 8. temp at 177. heat off. heat to 4.
01:30 - start collecting container 9. temp at 175. open valve. close valve.
01:32 - temp at 175.
01:37 - stop collecting container 9. temp at 187.
01:39 - start collecting container 10. open valve. temp at 193.
01:48 - stop collecting container 10. heat off. temp at 208.
02:26 - teardown done.
Collections:
*The temp in the above table is a guess. The temp varied throughout all the collections; it was more steady with collections 1-6.
*The T-T0 is the elapsed time from when the vapor reached temp (~168). This number includes waiting for the column to equalize. This number does not include setup time or tear down time.
