1 micron absolute depth/membrane filter Force carbing, so not bottle conditioning Bottle using blichmann gun. Sterilising with peracetic acid and purging with CO2 prior to filling

Hi All, Am filtering down to 1 micron absolute, pure tea kombucha. We are getting pellicle growth in bottle within 2 days of bottling. Usually no issue with this. This was the first time we purged bottles with CO2 and also previously only filtering to 2 micron absolute. Concluding that this...

Hi All, My refractometer started giving inaccurate results. I am testing a sweet tea solution. Adding 42g sugar per litre of tea and readings are coming in at BRIX 3.5. Usually they would be bang on at BRIX 4.2 I checked with RO water and reading is at 0. I bought some calibration solution...

Hi All, I use 40 plate chiller for cooling down sweet tea for kombucha production. Usually just flush through after use with 40L of 70C water after use. Needs a more solid cleaning as sweet tea residue caked on. I have peracetic acid 5% and sodium percarbonate. Can anyone advise on the best...

Hi All, Small scale commercial kombucha brewery looking for advise with filtration. Aim is for a final sterile filtered kombucha down to 0.45. Currently have a 3 stage cartridge set-up 5 nominal, 1 OR 2 absolute, 0.45 absolute. 1 and 0.45 absolute are clogging. A costly scenario. Want to...

Hi All, I'm a small scale commercial kombucha brewery. I need advice regarding cleaning and sanitizing my lines, kegs, filter cartridges and housing, crown caps and bottles. I've bought peracetic acid 5% and sodium percarbonate granules. Being based in India these are the most cost effective...

Thanks Brewbama

Hi All, I am carbing 6 cornys of kombucha via a manifold in chest freezer/fridge. I understand that you need to purge O2 from headspace. To do so I have been connecting all kegs to Co2 via manifold and then 1 by 1 releasing the headspace from each keg until it bubbles a bit. In doing so I've...

Hi All, Anyone know whether 0.45 filtration of kombucha would remove enzymes? Cheers

Thanks Russ. Can you recommend minerals to adjust flavour?

I am in India and despite having access to well water and government water I prefer to use my RO filter. I do not boil the water so cannot remove potential contaminants. PH of sweet tea is around 5 to 5.5 (if no water treatment)

Thank you for your help and suggestions. I'm a bit of a tea nerd. I find there to be quite a difference in a straight cup of tea, depending on the mineral content of the water used, I assumed that this would also translate over in to kombucha.

I would like to get the best flavour from the tea. RO water gives tea a flat finish. I want TDS around 150.

That's interesting, I've not heard this before. I do however wish to remineralise the water anyhow, so 2 birds 1 stone. Still keen to hear how people remineralise/raise PH of water.

My booch drops to around 2.5 when ready and with a higher starting ph it buffers this giving more like 2.8 to 3. So I'm still wishing to raise the Ph of my water.

My RO water is around 5.5pH, hence why I want to raise it

How do you raise the pH of RO water? It takes around 300mg/L of sodium bicarbonate to raise my water pH to around 7. I have played around with sodium carbonate and this required much less. I have also been using a mix of calcium carbonate and sodium bicarbonate. Keen to hear how others raise...

Yes the flavour is affected. The kombucha soured and acidified too quickly. Previously ferments were taking 5+ days and the result was less acidic than the current batch is at 3 days.

Hi, Please see the attached pictures of my brew after 48 and 36 hours. I ferment in flat tanks with a very large surface area and only 15 to 20cm depth and was having great results up until a recent pause in production. I am now facing a situation whereby within 36 hours my ferment is...

Hi, I'm wanting to sterilise new bottles using Vinator without need for further rinsing. Starsan not currently available here in India and usually costly. What alternatives are there that are no rinse steriliser for kombucha? Thanks
