The Mad Millie Culturing Flask is finally here!

We’ve been listening to feedback and know from experience how tricky it can be to maintain the temperature of your Mad Millie creations overnight. You spend time getting everything just right, add your culture and leave it in the warmest spot you can find. Only to come back the next morning to find…..nothing has happened.

It can be the most frustrating thing with yoghurt, coconut yoghurt, kefir and skyr!

Temperature is crucial to ensuring you give the cultures the right type of environment to grow and multiply. There are two different types of cultures used with Mad Millie food products, mesophilic and thermophilic.

Mesophilic is a non-heat loving culture, this is the most common type of culture used for cheese making and can only be heated to 40oC (104oF), any higher and you will start deactivating it. The more optimum the temperature, the better the culturing process which is why for a lot of cheese making a water bath and ripening period is required.

Thermophilic is a heat-loving culture and is used to make yoghurt, coconut yoghurt, kefir and skyr. It likes to be heated up to 55oC (130oF) and maintained at a warm temperature over a longer period so the cultures can do their job! This is where things get tricky as if you aren’t able to maintain the right temperature then the cultures won’t be working, and you’ll end up with a less flavoursome, runnier product.

Mad Millie Culturing Flask

This is where the Culturing Flask steps in!

Designed to perfectly fit the Mad Millie 1 L (1 US qt) jar this little flask of goodness will take out any issues with temperature. When designing this it needed to look appealing when sitting on the kitchen bench, be ridiculously easy to use and not require electricity as who wants to plug something in if they don’t have to?

At the very start of your yoghurt making experience boil a nice full jug of water. Pour this into the Mad Millie Culturing Flask and seal.

Go about your yoghurt/coconut yoghurt/ kefir/skyr making until you have sealed your jar and it’s ready to ripen. Pour the water out of your Culturing Flask which is now nicely pre-heated and pop the jar in. Seal and leave on the kitchen bench overnight.

It’s as easy as that!

If you need to culture longer than 12 hours, we recommend opening the flask up in the morning, removing the jar and refilling the flask with boiling water. Let it sit, sealed for a couple of minutes to ensure the inside is nice and warm again before pouring out the water and replacing the jar. This will ensure the most optimum temperature throughout the whole process.

We hope you love it as much as we do, making yoghurt has never been so easy.
