Kombuchaorganic Avaliações 

Excellent service. The SCOBY that was provided was top quality, producing excellent high-quality Kombucha. Can't recommend it highly enough. A star.

I purchased this SCOBY after seeing “Item volume: 1 gallon” on their Amazon listing, along with directions stating: “Use 1 SCOBY and 1 cup of starting fluid per gallon of sweet tea.” This clearly suggests the product is intended for a full 1‑gallon batch and that the starter liquid supplied will be adequate for that volume.

However, the SCOBY arrived with only 100 ml of starter kombucha.

Scientifically, a 1‑gallon batch requires 300–500 ml of mature starter tea to lower the initial pH below 4.5, which is essential to prevent mould growth. Even their own Amazon instructions (“1 cup per gallon”) indicate that 240 ml is the minimum. The 100 ml provided is significantly below any safe guideline.

Their printed instruction sheet describes a small‑batch method (around 1 litre of water with 4–5 tea bags per litre), which does not align with the “1 gallon” wording on their Amazon page. More importantly, their instruction sheet also advises sparing approximately 400 ml of kombucha with the SCOBY for the next batch. This strongly implies that a healthy SCOBY should be kept - and therefore supplied - with a substantial amount of starter liquid. Supplying only 100 ml contradicts their own instructions.

I contacted them through Amazon’s “Contact Seller” system and provided a detailed explanation of the acidity issue, the batch size mismatch, and the scientific requirements. Their entire response was: “we provide 100 ml, it is enough,” followed by a request for photos of the mouldy SCOBY. The SCOBY had developed white, fluffy mould, and I had to dispose of it immediately to avoid contaminating my kitchen. Keeping a mouldy ferment for photography is not safe practice, and the lack of photos does not change the underlying problem: the starter volume was insufficient.

Because I had prepared my equipment for a full gallon - which is normal when purchasing a large SCOBY and consistent with their Amazon listing -I had no choice but to add distilled white vinegar to compensate for the very small amount of starter liquid. This is a recognised safety step in fermentation when insufficient starter tea is supplied, and it does not cause mould.

Despite sterilising all equipment, using filtered water, maintaining correct temperature, and following both their instructions and standard fermentation practice, the batch developed mould within a week and had to be discarded. The SCOBY even began forming a new layer, showing the culture was alive, but the acidity was simply too low to protect it.

I genuinely wanted to support a small business, but the amount of starter kombucha they supplied is not sufficient for the batch size implied by their Amazon listing and their own instructions. This makes failure likely even when the customer follows the process correctly.

Everything seemed to go well with the kefir grains I had ordered and I followed the instructions. As explained it took several days to get any reaction but, although some pockets of air/gas appeared the mixture didn't thicken at all and tasted of very little except sweetened milk.
I have been culturing Kefir for several years and never had this experience! I have continued trying to culture it for several batches but no change!!
I'm thinking of throwing this away and trying to order from another supplier

Finally found a company who truly knows about milk kefir grains. Arrived in perfect condition in hermetically sealed bag and once set to work, produced delicious kefir in 24 hours. Easy instructions and happy to know where to get replacements and other superfood stuff.
Very happy to recommend and will be buying other products. Thank you

I’m only leaving a review because I read the very bad reviews after ordering the kefir granules and I was concerned. They arrived promtly, well packed, with instructions. I left them in the fridge for a day and I’m now on my second batch using fresh organic milk, but homogenised as I could not find any non-homogenised. The granules are working well, the kefir tastes much better than the ones from the shops and I’m very pleased with the product. I will recommend this seller.

I purchased a 50g batch of live water kefir grains from this seller, but the grains arrived completely dead and dormant. I gave them a thorough, fair trial across six separate batches, but nothing happened. The liquid remained completely flat, intensely sweet, and smelled like plain sugar water, with zero fermentation or signs of life.

When I opened a return for a defective product, the merchant chose to exploit a loophole in the marketplace return rules. They deducted 50% from my refund, claiming the item was not "returned in its original condition."
This is a deeply dishonest and predatory business practice. It is completely impossible to test whether a live food culture is viable without opening it and attempting to brew with it. Penalising a customer for trying to use a product that arrived faulty is shocking customer service. They are weaponising this loophole on perishable goods to avoid giving full refunds for dead stock. I had to force customer services to step in to recover the rest of my money. I highly recommend avoiding this company entirely.

I don't usually write reviews but given the poor reviews for Kombuchaorganic on Trustpilot I have felt compelled to share my experience. I came across this company via an online search as my existing water kefir grains which had worked hard for me for 10-ish years were struggling and needed to be permanently retired. Kombuchaorganic's prices were great and organic status an unexpected bonus. I placed my order for 100g of water kefir grains and received a 'shipped' notification within 24hours. 6 days later I had not received the delivery and then came across the Trustpilot reviews. Reading many of them I immediately feared the worst - perhaps either no delivery or poor quality grains - but that evening got home from work and the delivery had arrived. 2 sealed packets (50g each) of beautiful grains. I fed them straightaway, then refreshed the sugar water 2 days later. 3 days after that I harvested my first batch of water kefir from my new grains. I always then do a secondary fermentation which I flavour with wild blackberries (which I pick every autumn and keep stocks in the freezer to last me until the following autumn). Theses grains are making delicious kefir water - a light fizz but smooth and fruity. I am glad I didn't see the trustpilot reviews before | placed my order - as perhaps I wouldn't have taken the chance. But I am glad I did buy from Kombuchaorganic and my experience of them and their grains has been nothing but positive.

The worst service I have ever had with any company. Selling dead cultures from their own kitchen. Know exactly what they are doing … this is the response O received . Estera Gebura - Hi, you ordered 10g of grains and this is how much we provided so no refund will be made and we will refuse charge back as tracking proves delivery, feel free to order from somebody else. Be very aware this lot are scammers and disgusting people. I will be ensuring I get them shut down.

Absolutely pathetic amount of grains complete disgrace will be invoking a chargeback as company is just dire

Damn why didn't i read the reviews on here first?

Took 8 days to arrive. Grains were so small and, unsurprisingly after 8 days in transit, dead.

So fed up I can't even be bothered to contact and request a refund.

Same experience as everyone else. Wish I seen this first. Grains sat in transit for a week - won’t work. No reply to email.

I've seen a couple of reviews here stating this is run from a residential address and has been reported to trading standards etc. No idea where people get this info from but I purchased from ebay which gives the sellers name and so forth. It's been a registered business with Carlisle City Council since 2012 and has passed all the certificates etc that it needs to run as a business hygiene /safety etc. I think a lot of the time people buy something like this and don't know how to do it or follow the instructions properly. I bought milk kefir and left it out too long so learned from my mistake and make it fine now.

DO NOT BUY! Selling dead cultures, BEWARE!
Extremely hostile and rude

I purchased kefir grains from kombucha organic uk and when nothing happened after 4/ 5 days with the fermentation process, I contacted them. I received a curt email response and then no further acknowledgements and when I requested a refund as I was so disappointed, they totally ignored my emails. I received a similar kefir grain product from a friend recently and it has set and ready to enjoy within 48 hours being kept in the same conditions as instructed by kombucha. Not a very honest seller👎👎

Hi there , I recently bought some sourdough-starter from Kombuchaorganic . I live in France so the delivery took about 10 days . After an initial slow development I learnt , while testing out the starter , a very useful lesson , a point which is mentioned by them but could easily be overlooked : do not use tap-water as the chlorine kills the starter . Once I realized this (by switching over to rain-water ) , it worked very well and continues to do so. The other important point is to have a temperature of 25 to 30 °C . At the summum of it's growth , the starter is not very acid and indeed tastes quite sweet so the bread is delicious . Thank you .

I have bought water kefir grains from this company in the past without a problem but my last batch were sub standard.
Emailed as there is no contact phone number and got rude abrupt messages.
No offer to replace the substandard goods or any type of decent customer service.
It's worth paying a couple of pounds extra to receive decent grains.
Since my purchase I discovered kombuchaorganic have been reported to trading standards by other suppliers, they work from a residential address and do not adhere to food hygiene standards

I ordered 2 packs of their Kombucha Starter Kits for 5 litre. Goods arrived in time, but the SCOBYs were quite small, one most likely adequate, but the other very small. There was a big difference in weight between the 2 packs, and their should have been 500ml of starter tea with each pack. The total amount of starter liquid was 150ml. I have tried to contact them several times, and although I got a response, they just stated that the goods were delivered. I asked to return the packs - no response.
When you look at the business address, it actually is a residential address.
I can only recommend to stay away from this company, there are more reliable suppliers on line
Just for verification to the seller, it was order #3673

Bought a Sourdough starter through their online shop. Was sent a tracking no. in PayPal only which I saw by chance as I don't normally pay that way. Delivered by 4th Jan. in ipost box. no email or code sent to me by email or text to confirm delivery or where to pick it up from. I have tried to contact them by their email 3 times (no number on website) WITH NO REPLY BACK! Very disappointed indeed... I go to Cumbria often so they'll be getting a surprise visit for sure, that's if they even exist there!!!!!!!!!?

Bought Sourdough starter and never received it despite that showed that it was delivered on the tracking. Email them to make the aware and see if they could share some light into the issue and they respond was , "Sent with this tracking number " email them again 3 times and never got a response. It's been reported to trading standards. DO NOT BUY FROM THIS COMPANY!!

Poor, poor, poor customer service!
Grains did not work...despite a retry under their instructions.
In terms of communication and customer service unfortunately this company scores nil points! FOR EVERY REPLY I received I had to send about 3 emails. They offered to send out a new supply of grains which I did not receive. The reply back was offensive and abrupt. I have been left £9 out of pocket and very frustrated! I hope nobody else has a problem - settle in for a long- haul email cat and mouse chase!
