1. Do strips. Use all the wash, in as many strips as you need to fill the boiler for a spirit run. Combine everything you already took except the fores and call it a strip, yeah. Hard to do but it's not looking good how it is.
2. Get more jars. You need more, probably twice the amount. At least 10-12 or so. Take smaller amounts in each.
3. Take all the jars and let them air for 48hrs with a coffee filter or paper towel on the top and point a fan at them to air out.
4. Make cuts by nose from the middle, where you think it smells good...where the hearts are. Work to the tails and make a preliminary cut of where you can first smell stinky tails. Then work to the heads and do the same. Stop when it smells worse than the hearts.
5. Then starting for the tails side take a few drops of the jars in your hearts from the jars at end of the good cut and water them down and re-evaluate by smell and taste to make sure that they aren't nasty and cut out anything nasty. Then try some of the jars that were cut out in the same way to be certain nothing good is cut. Then go the heads side and do the same.
6. Then you can combine the known to be good hearts and test for proof/abv %.
7. After you do this several times and get better at it and the process you can adjust to your own preferences.
Small amounts are really hard to work with, and yours are teeny tiny amounts in not enough jars at a too low proof. The more jars, the better the cuts can be. Get it? And your abv % should be higher, a low abv means that not enough separation was happening. It could be because of the overall small amounts of wash run, or that it run too fast and everything smeared into itself. The still itself and the small volume of wash was probably the biggest problem. If you can run the spirit run slower somehow, it will help big time.
You already have that one, I know you want to make it work, but the real step 1 would be to buy/make a bigger still or boiler. Your amounts are too small to realistically work with. With your still I would only put about a tablespoon in each jar. A 3-5 gallon still will allow you to use more wash so that you'll have more product to separate into jars and evaluate for making proper cuts. The bigger the better, just like with aquariums. Just one drop of bad stuff can ruin a whole batch, and the smaller the batch the harder it gets to keep it clean.
A flame test... I have no idea what that shows or doesn't. Go by senses! Something may burn yellow or blue or both depending on abv, type of product, size of spoon etc. Same with measurements. Use your nose first, then your tongue to make cuts.
Ageing at 80 proof will be...interesting. Next time age it on wood between 100-130 proof, different proofs pull different flavors from wood. I have no idea what that will end up tasting like since I and every distillery in the world has never done it.
