Re: Any idea why this is coming out blue?

Had a quick Google and it's very inconclusive as to whether plastic will leach into the first run - especially at low Concentrations and a short time space like 6 hours?

Re: Is this potassium carbonate safe?

I don't see why it shouldn't be safe, within limits. It was used for years as a leavening while baking quick breads, and as an additive in beverages – like wine. But I don't understand why you would choose to use it, when it's expensive and probably less effective than lime (calcium hydroxide / whi...

Is this potassium carbonate safe?

Hey all, Normally i buy small batches of potassium carbonate off ebay labelled food grade. I've recently moved towards a bigger fermenter (200L) and so the small amounts i can buy off ebay aren't really enough. I've found an online chemical supplier selling what they call "Potassium Carbonate A...

Leaking Compression fitting on my proofing parrot

Hi all, The compression fitting on my proofing parrot drain is leaking... there isn't enough space to remove the nut and replace the plumbing washer thing (i know v stupid of me). This also means there isn't enough space to move the nut far enough away from the compression washer to wrap it in PTFE....

Re: Having trouble running my VM on a Neutral spirit run

Sounds like your well into the tails. ABV will rapidly drop, temp rise, and product not drinkable. Your run is done. You harvested most of the alcohol on day one. But your yield calculations are off. Either a specific gravity reading was wrong, or you lost alcohol vapor through the top of the still...

Re: Having trouble running my VM on a Neutral spirit run

Big L, have you confirmed whether or not you are losing vapor out the top of your still? If your running your reflux coil too hot then vapor will pass right past the coil. Also I'd stuff copper mesh in and around the coil and that will help. On this page there is a good guide to running a VM still....

Thanks for the wise words everyone - I think i need to sort out a electronic temperature sensor and a valve i have more controll over - its 42mm ball valve at the moment.

Re: Having trouble running my VM on a Neutral spirit run

[*] Off a 40% charge like yours I would have expected quite a bit more. In my VM the tails can come suddenly, but always preceeded by a rise of ~0.2 deg. C. I can hit tails while still above 91-92%. [*] If I take too much product too quickly, I'll smear tails. I can take 2.5L / hr wide open, but mo...

Its mainly going fine and was getting a fairly consistent 94% - a few times it would drop off and then all I would do is shut off the valve and let it re-equilibrate. I am making small adjustments to the cooling water to keep the coil condenser outlet at between 40-50 DegC I have also been gradually...

Yeah sorry for not being clear: I will load the boiler with 35-40% - what i am asking if loading them separately is worth it. One which was over 10% and one under 10% at the fermented wash stage (but have now both been stripped). Annoyingly Shadylane I don't think i'll have quite enough of the under...

WPOSW - Importance of keeping below 10% with VM reflux still

Hi All, If running a VM reflux still how important is it to keep the wash ABV below 10%? I understand why it would be important with a pot stills but if you're going for a neutral with all that reflux would it still make a difference?

For the Sanke outlet common to your T/C ferrule, just sand the bead off of the teflon gasket. I put 120 grit sandpaper on a flat surface and hold the gasket with the ferrule, slowly sliding it back and forth. The bead will sand off and you’ll have a flat surface on the gasket to match the keg fitti...
