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

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...

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
