Distilling old brew.

Postby Sandman » Thu Dec 12, 2019 8:22 pm

I put down a brew using raw sugar, molasses and turbo yeast. This was about 8-9mths ago. I had intended using an old 5 lt still that I hadn’t used for near 20yrs. But the element was burnt out, so the brew has been sitting in the fermenter since then.
I recently bought a T500 still, so I ran it through to see how it went. Made 3 1/2 lts @ 91% ABV. I ran it through carbon filter.
It has yeasty smell and kinda sweet taste. Not a nice clean smelling spirit. Not sure if it because it’s been sitting so long, or after reading what people say about turbo yeasts, maybe that? Or both?
Would it be worth running through still again? And maybe taking off more heads again?

I also recently put in a brew of 6kg white sugar and turbo yeast. It seemed to be going ok for 3days, then stopped. Left it for a couple more days, but no more activity. Checked with hydrometer and it was 1.22SG. The ambient temps have been pretty hot, so it has been brewing between 30 - 36C. Could that be the problem? Is there anything I can do to get it going again?

TIA

What you have made is rum with a poor choice of yeast. Even the best reflux still will have trouble stripping rum flavour.. from rum..

I’ll agree with Nathan.
Plus, the molasses makes one hell of a mess if your packing

So, perhaps if I just put it on a light oak, and make it all into rum, it might be ok???

If you did cuts, it might be. Be patient too. Oaking can take months. What were you intending to make? Neutral or rum?

Was going to make rum, but it got forgotten about when the old 5lt still died.

I used SS turbo yeast a few times (in the early days when I was learning), and I never had a distillation coming through "yeasty". I'm thinking that may be caused by how long you left the ferment. I would run it through the still again to see if the flavour improves
