When treating feints with slaked lime, are you adding it at a ratio, testing the ph and if testing, are you using litmus paper? I have a digital ph meter, but never tried using it with anything other than a wash. I've used Sodium Carbonate in low wines and feints many times before, but it was at a ratio that I read about and I didn't measure the ph. I quit doing that because something didn't sit right with me, treating to raise the ph without understanding what was actually happening or knowing what the ph was. I'll have to revisit that, study the info again and also search using 'slaked lime'. I understand slaked lime is also referred to as Calcium Hydroxide. I have a lot of Calcium Hydroxide I bought cheap on sale.NZChris wrote: ↑Wed May 15, 2024 11:29 pmThis is something that wasn't answered.
I've always had copper in the main boiler & still head, plus I'm heating with copper elements in the still and copper coil in the preheater. That may be one reason why I've not noticed much difference when running cleared sugar shine compared to murky, compared to other distillers with less copper.
A trick I've been using lately, with success, is upping the pH of Low Wines to over 7 using slaked lime. I buy it at the local building supply store for bugger all. A sack lasts me for years. It also works to precipitate undesirable VOCs out of feints before re-running them. A conical tank would work well for that too, but I don't know that it would be a 'must have'.
For a few years now, I've been saving my feints for an All Feints run through my Bokakob to make high quality neutral, but the slaked lime has been working so well at removing VOCs before the run that I've been experimenting with running it through a pot still instead and I've been very happy with the results.
When I don't clear a wash, tails are very strong (odor & flavor). When I clear a wash, tails are really feint in comparison. Cleaner in = cleaner out and that seems to be the case, at least in my experience. People always say, "when making a clean neutral, the further away from the yeast the cleaner it will be". This is the thread that got me first interested in trying to clear a wash.
