Sediment / Cloudiness in Spirit

6 posts in this topic

I'm working on some formulations for a new product using pre-distilled 190pf base spirit, then adding water, sugar, and a few flavor components. I'm using RO water and have confirmed that the flavors are completely water soluble. At some point after blending (typically a few weeks) I've noticed that a white sediment-looking formation collects at the bottom of the bottle. When it is disrupted it "floats" upwards and disperses throughout the bottle, looking similar to rising smoke. When you shake the bottle heavily, it disperses completely but only to return within a day or so. 

I've confirmed that the issue is not caused by any type of bacteria, calcium in the water, or other potentially obvious things. I initially thought cold temperature was the driver, but I've tried putting it in the freezer and it doesn't seem to directly cause the issue. Has anyone ever encountered this before, or do you have any insight into what might be causing it and how to eliminate it?

It'd guess minerals in the water.  Do you have a TDS meter? Are you using an ion exchange column after your RO system?

Probably either minerals (your RO system not working well) or your water soluble ingredients fall out of suspension in the alcohol/water solution.

@IndySpirits thanks for the response and yes to both, so I've been thinking more and more that it's something besides just minerals in the water.

I would think it is the added flavour components are NOT completly completely soluble in your mix. For interest carefully pour some of the clear liquid off the top of a bottle with sediment. Replace with some neutral and see if the sediment dissolves.

Also try leaving out one flavour ingredient at a time to see if one is causing the problem.

If you are happy with the taste of your product then leave to settle out the sediment for a few weeks before filtering and bottling.
