First runs have problems

[HOUNDOG]

Hello,

I have been reading everything I can about distilling and have attempted my first two runs. However, I did have some problems. I am using a Brewhaus 15 gal pot still, a mash of corn and sugar fermented with turbo yeast. I usually extract the sugars from the corn using a mash tun (like an all grain beer batch) and add sugar to around 1.100 SG. The runs have fermented down to 1.000.

My first run was ok, but had a bad burnt popcorn smell as it came off the still. I aired the jars out for 24 hours and the smell went away. However, I made the cuts of the heads/tails (I collected 200ml per jar) and cut the product with distilled water (purchased). When I cut this batch, the product became very cloudy, still transparent but cloudy. Any ideas of why this happened. Note: I ran both runs at about 1-2 drops per second.

I ran the second run with the turbo yeast still bubbling on the top, however FG was at 1.000. The product is clear from the still but has a very sharp aftertaste. This taste is similar to vomit!! Overall the product looks good but it has the nasty aftertaste. I havent cut it to see if it turns cloudy because I am going to attempt to run it again and avoid the aftertaste. Note: Same collection method as before- 200ml per jar at 1-2 drips per second. This run took 20 hours to complete and I still had 50% ABV when I shut it down.

Any help would be great!
