et1883 Posted September 19, 2019 Share Posted September 19, 2019 ISO best idea to filter very fine dust and particulate matter from a compounded gin we are working on. Don't want floaties or what a customer might think would be foreign matter in the bottle. Thanks in advance! Link to comment Share on other sites More sharing options...
glisade Posted September 19, 2019 Share Posted September 19, 2019 Some cheap filter bags work well. http://www.dudadiesel.com/search.php?query=%2Bfilter+%2Bbag+%2BPTFE Link to comment Share on other sites More sharing options...
et1883 Posted September 19, 2019 Author Share Posted September 19, 2019 very interesting idea, and cheaper than a $000 machine. we have been thinking to basically rack the gin as if it were a home batch of beer, leaving dust and debris at the bottom, using a siphon approach. this looks compatible with that idea.

Glenlyon Posted September 19, 2019 Share Posted September 19, 2019 We use those filters - not so good with fine particulate matter. We've taken to fining some of our spirits to get that nice bright look. Link to comment Share on other sites More sharing options...

glisade Posted September 20, 2019 Share Posted September 20, 2019 I would start with filtering as low as you can go with the cheap bags..usually about 0.5 micron. Then let the spirit sit for 1-3 weeks and see if anything drops or separates from the spirit to a non-acceptable level for you. Then start experimenting with fining agents. I fine with bentonite after filtering to 0.5 micron for a couple of my liqueurs and it works well. Some just don't need anything more than a good level of filtering.

Glenlyon Posted September 21, 2019 Share Posted September 21, 2019 Chitosan. However, a problem we are encountering with the fining is now we have sediment on the bottom of the tank. Of course with the tanks being stainless, it's hard to see inside to avoid sucking up the sediment - this tends to leave product on the table. So, the jury is still out.

Silk City Distillers Posted September 21, 2019 Share Posted September 21, 2019 Fining in spirits? As opposed to straight filtration? The only filtration aid I've ever seen in wide use was diatomaceous earth (DE) used with larger plate and frame setups. 0.2 or 0.1 micron and done, it sparkles like diamonds.

Afilters Posted January 27, 2020 Share Posted January 27, 2020 Hi, Is this still an issue? If so, I would be happy to help figure it out. Thanks, Alex Link to comment Share on other sites More sharing options...
et1883 Posted January 28, 2020 Author Share Posted January 28, 2020 we're good. we reduced the % of botanical load and combined with 0.5 micron filtration. We were OK on proof, but had more botanicals than required for we wanted to achieve. Link to comment Share on other sites More sharing options...
