Organic Greek Yoghurt Starter Culture


Our organic Greek yoghurt starter  is a heirloom “Greek-style” yoghurt starter which means it can be recultured time and time again. Our culture contains the bacteria Lactobacillus bulgaricus and Streptococcus thermophilus

Organic Greek Yoghurt Starter

Traditional Greek yogurt is made with goat’s milk and strained to remove any whey to produce a very thick cultured milk product. Traditional Greek yoghurt is not a heirloom culture. You are unable to reculture it indefinitely. Many of the “Greek-style” products you find in the supermarkets are made from cow’s milk and a thickening agent. Our organic Greek yoghurt starter  is a heirloom “Greek-style” yoghurt starter which means it can be recultured time and time again. Our culture contains the bacteria Lactobacillus bulgaricus and Streptococcus thermophilus

Our organic Greek yoghurt starter produces a very airy, thick yoghurt that is often full of bubbles. It is the kind of thing you are used to buying from the supermarket as a “Greek-style” yoghurt. The great thing with our culture is that you can make it at home without the need to add sugar, preservatives or emulsifiers. This is a thermophilic yoghurt. It requires a yoghurt maker to be able to work with the culture. These can be picked up online reasonably cheap (less than £20). If you’re looking to make supermarket style yoghurt at home. This is the culture for you!

  1. melinda says:

    Hi, i would like to make greek style coconut yoghurt, I have read in another blog that if i use a bit of sugar to feed the culture i should be able to use this starter, do you have any experience of doing this? thank you

  2. Rachel Ratcliffe says:

    Can I use raw cows milk to make Greek yoghurt with? If so is there any change to the instructions?

  3. Natalie says:

    I’m new to yoghurt making. Is it possible to make this organic Greek yoghurt fat free? Or, reduced fat?

  4. Megz says:

    I’d just like to know before placing an order, can your culture’s be added directly to milk to produce yogurt or does a starter solution have to be made first?

    1. Freshly Fermented says:

      These are added straight to milk

  5. Rob says:

    Your greek yoghurt instructions recommend a temperature of 42C for at least 10 hours. This consistenly gave me very grainy yoghurt – nice flavour, but nowhere near the smooth integrated texture of commercial greek yoghurt. After much experimenting I now get perfectly smooth creamy yoghurt by leaving it overnight (8-9hours) in a proofer at only 33C. Any temp above 35C seems to result in grainy yoghurt with lots of whey leakage. Why do you recommend 42C? Is this purely a food safety issue?

    1. Freshly Fermented says:

      No, we have always had great results at 42c.

  6. Alli says:

    Hi there Could you confirm the full ingredients of your greek yoghurt starter culture? Is there any powdered milk in it? If so, is this goat’s milk? I don’t take cow’s milk and will be using goats milk to make this yoghurt. Is it suitable? Many thanks Alli

    1. Lisa Hillyer says:

      Hi, the yoghurt has been made with organic whole cows milk and then freeze-dried so it would initially have traces of cows milk in it. However, you can convert it to goats milk and after a few ferments there would be no trace of cows milk in it. Thanks Lisa

  7. Carol says:

    How do you make second batch from first made yoghurt

    1. Lisa Hillyer says:

      Hi Carol, you just take a couple of tablespoons of the yoghurt you have made to use as the reculture and follow the same process as you did to make your first batch. Thanks Lisa.

  8. Tamas says:

    Hi. I bought on website Greek Style yoghurt starter. This is came as a 1G bag. My question is, I need to use all 1G starter to 1000ml milk?

    1. Freshly Fermented says:

      Hi, yes that is correct.

  9. Kelley says:

    Hi–I made some delicious greek yoghurt with this culture, but the initial batch was slightly grainy in texture. If I use the reculture from a grainy batch, will the result always be grainy or is it down to something I’m doing in the process? Thanks!

    1. Lisa Hillyer says:

      Hi Kelley, The re-culture should be ok and sometimes it takes a couple of goes to settle in. Try again and if it keeps producing the grainy texture then please contact us on and we will replace it for you. Thanks Lisa

  10. Ann says:

    Is it possible for me to have a Bulgarian and Greek culture in my fridge at the same time. I would like to make a pot of each every week. Thanks

    1. Lisa Hillyer says:

      Hi Ann, yes it is possible, you would just need to keep them in separate sealed containers and they will be fine. Thanks Lisa

  11. annette wass says:

    Hi I have a food flask kind of yoghurt maker but it only holds 500 ml -can I freeze half of the starter culture ?

    1. Lisa Hillyer says:

      Hi, you won’t need to freeze the starter as they have a 2 year activate by date on them so can be kept at room temperature.

  12. Pavonia says:

    How many starter amounts are in the supplied packet?

    1. Lisa Hillyer says:

      Hi, these contain 1g of starter per sachet which produces 1000ml yoghurt and is heirloom so can be re-cultured indefinitely.

  13. Clem says:

    Hello – can I use the greek yogurt culture to make yogurt without using a fine sieve at the end like to describe in your instructions? Many thanks

    1. Freshly Fermented says:

      Sure, it just won’t be as thick without straining it. It’s not a requirement for the bacteria, just our own tastes.

  14. Sharon says:

    Hi I wanted to make Greek yoghurt. If I didn’t want to make it for a few weeks can I keep it to Re culture or is it ruined?? I understand that if I do it every seven days then I can use it indefinitely but what happens if I don’t eg…if I go away on holiday? Thanks

    1. Lisa Hillyer says:

      Hi Sharon, you can freeze the reculture ready for use when you are back from holiday 🙂

Delicious creamy yoghurt

I have made about four or five batches now with this yoghurt starter, sometimes using goat milk. Sometimes using cow's milk. Sometime using half and half he'll stop. I strain it to make a delicious creamy yoghurt..

Mary Visser

Made beautiful yogurt first time. I then retained a small amount of the yogurt from the first batch and supplemented with a bit of strained whey. The second batch was great too. Hopefully I can repeat indefinitely!

Julie Sanderson
Absolutely fantastic

I wanted to wait a while before writing a review. This is totally game changing. I have been using a small yoghurt maker and shop bought yoghurt for years. I could make 2 or. 3 batches then have to buy a new starter. This is a totally different experience. I’ve started using my multi cooker so I’m producing 3 pints at a time The yoghurt is consistantally beautifully smooth, it tastes amazing - I can’t put my finger on it but it somehow has a fresher taste, tastes really natural. It makes fantastic ‘cheese’ when drained for long enough.
And there is no deterioration in the product even after several months. It pays for itself within a very short space of time. You really need to try this

Per Norrgren
This is amazing

This is amazing, it made the thickest yogurt I have ever seen! Like a lump I picked up out of the straining cloth. Mixed a bit with spatula and it is more like a very thick soft cheese. Love it. Like triple clotted cream. Used 1000g full fat fresh milk, boiled to 90+ centigrade for 15 min, rapid cool, 42 degrees centigrade for 10 h drained for 8 h. Left with 350g “yogurt” and 350g whey. Thank you.

Lucy Nield
