Why did you add calcium carbonate (oyster shell) to a wash that was already high (at pH 5.7)?
It is not needed and potentially could cause the wash to turn caustic (too high of pH). Oyster shell is for raising the pH of an acidic wash that has a pH that is crashing (< pH 3.5).

Indeed, why the hell did i do that ? too much whisky last night, only excuse i have.... Just been upstairs to check and remove the said shells, my p.h. is now at 4.5 ? Would rising the temp have helped things?
Fermentation will produce acids during the process. And just a few hours in a nearly neutral environment, the shells would NOT contribute much neutralizing effects. So, I’m not surprised your pH has dropped to 4.5. That’s a good indication of a healthy start. If it continues down to 4.0, or below, then add the shells back in. Otherwise, relax...it’s fine.
ss
Yes, it's dropped from about from 5 to 4ish over night,....thanks for your taking the time to reply, everything you have said to me makes sense, on both threads.....
Your an excellent teacher....Thank you...the only thing now is your stuck with me for life......

If any sugar wash of mine has a pH around 4.5 the next day, I add shells. Not grit, whole shells.
Yeah Chris, i have 5 mashes running at the moment, getting a bit ahead of myself...i bought 15 medium oyster shells last week, there is hardly anything left of them...just had delivered 25k of crushed oyster shells ...you may call them grit..? i don't see a problem with them, unless you know different ? thanks for your experienced help..

Crushed behaves differently because of the larger surface area making it a lot easier to make a mistake.
Chris.. would mind clarifying the statement.. maybe in your mind it adds up, but not in mind..

My TFFV is waaay behind schedule, thank you for your post, my p.h.is around 5.7....have added oyster shell,
If I am not wrong, 5.7 is not a high acid reading at all and you don't need oyster shell, not that it will have a negative impact I expect.
Oyster shells are used to bring the acid down, which means increasing the ph.
There is a fair bit on the site here about adding oyster shell at the beginning of the ferment to prevent a ph crash and that ph typically stabilises after a 24-48 hours.
If I see that reference again I will post a link.
Good luck
Taking a break while I get a new still completed....

For a wash, an acidic environment of Ph 4 is the best.. lower and the yeast are affected.. and higher is somewhat ok, but not the best went come to stripping the wash.. when a high Ph is at the end of the ferment, it is best to lower the acidic level to a 4.. if it's not lower the wash will foam/puke much more than normal, plus the wash will not clear as well..

Hi.
On the first page in "formula" is "...250g wheat bran..." can I replece it with 250g of wheat flakes or crush wheat malt? Or it's the same ? Thank You for answer.

Not sure if you are using a regional terminology that represents the same thing but wheat flakes sounds suspiciously like some type of breakfast cereal and I saw mention on this thread to not use it. Crush wheat malt? I don't know. I would spring for the $1.5CDN to do it with wheat bran atleast at first.

not sure, but wheat bran is the hard outer layer of the wheat kernel, which is 'quote' jam-packed with various nutrients and fiber.(esp vit b)
it's in the breakfast cereal section in my local woolies, just sold as 'wheat bran'.
looks like fine breadcrumbs TBH.
I went with the bran deliberately. As said it has nutrients and fibre but not the kernel or germ. The germ adds oils which changes the subtle flavours. That little wheat grain is a rather complex beastie and the bran is what helps the germ to sprout if left. In addition I found it available very inexpensely.
Thanks to all for the positive comments.

Well here is a negative one!
I went to both Woolworths and Coles last night and there was no Wheat Bran and I blame you Teddy and your damn good TTFV!
I reckon it is sold out because everyone is making TTFV!!!!!!
i don't understand why you can't get it, i bet some people are probably hoarding it
woolies have it in plastic bags, usually hidden on their bottom shelf, hard to spot sometimes.
the packets look like this....

oops lol
That's my point, they are hoarding it to make TTFV!!!!
Its you!!!!!!!

Got one of these fermenting now. It's 30L and started 3 days ago. As I'm in Australia, I had to adjust the recipe slightly. No DAP so replaced with two caps of hydroponic nutrient from bunnings. Boiled the bran and added 50g yeast as nutrient - yes, yeast boiled so dead. Added 50g anhydrous potassium carbonate (pottery supplies) and 20g citric acid to bring starting PH to 6.6 and hoping it'll act as a PH buffer. 5.5kg sugar gave a S.G. of 1.07. Added 6 oyster shells in a sock as it's the time of year to put stuff in socks! Added 50g more yeast to get it all going. Yup, went off like a rocket. Not bubbles but burps, if you say burp as fast as you can, that's what it sounds like. Anyway, today, 0.99 S.G. but still gassing so will leave until tomorrow before stilling it. BTW, why do people leave it to settle? Doesn't the act of boiling it mix it all up again? Or do they siphon and leave the dregs behind?
Will still it tomorrow (reflux) even though those little guys that have been working so hard will get killed in the process.

Hi Pommie,
I ordered some DAP online, I think I got 1kg for buggar all (told the wife it was mexican marching powder)
If I may, your ph seems high at 6.6, I am usually kicking off at around 5.2-5.5 and that is with a half teaspoon of citric acid.
your oyster shells are the ph buffer from what I understand and 6 oyster shells is a lot, I use 1 sometimes 2, just saying as I can't always get my hands on them. You should be able to take them out after 24-48 hours also (from what I read)
Other than that, it sounds like you nailed it!
Finally, where did you get your wheat bran, woolworths and coles have been sold out for weeks now!
Taking a break while I get a new still completed....
I've got wheat bran from both. The 6.6 start PH is a little high but the yeast doesn't seem to mind and it drops to 4.6 in a day. Currently 4.4 and I'll retrieve the sock in the morning. I figure it'll only dissolve what's needed to cancel acidity. I'll have 10% in the morning so 3L of pure EToH plus the heads and tails from the last run - about 2L of 80%. Should get 2.5L of 96%. Happy with that.
BTW, my girlfriend insisted the sock had to be new!!! I figured EToH kills everything.
Pommie.
P.S. Wheat bran in cooking isle in Woolies and breakfast cereal in Coles.

Pommie.
by racking you syphon off the liquid and degas it to allow most of the still suspended solids fall out of suspension before siphoning the cleared Liquid into the boiler, leaving the dregs behind. This gives a cleaner distillation

And if you leave the dregs in a (covered) glass container you can (visually),
after resting for some time, pour some more nice clear stuff off THOSE dregs...
Found out today that boiling 32L in a 35L boiler leads to foaming and crap coming over. Ended up turning it into a stripping run and starting a new wash. Should be complete on Wednesday and will strip that also and then do a spirit run. You live and learn. Had to strip down the column and wash all the packing. Half my packing is Stainless washing "blobs" that went through the dishwasher and the other half is copper mesh that came with the still. The stainless appears perfect, the copper discoloured. I'm thinking more stainless is the way to go. Opinions?
Just been upstairs to check and remove the said shells, my p.h. is now at 4.5 ? Would rising the temp have helped things?
