    Natural fermentation

    We ferment for a minimum of 48 hours with live cultures, and we never pasteurise. That is what keeps the probiotics alive.

Made by the people who actually study this

Blessverage started at home. Our child struggled with GERD and found real relief in kefir, but genuinely good kefir was hard to find in Indonesia. So we started making our own.

Two of us hold doctorates in the fields this depends on, and the culture we ferment with has been kept alive continuously since 2019.

Questions we get most

What is kefir?

Kefir is a probiotic drink made by fermenting live cultures of beneficial microbes, on either milk or sugar water. What you drink at the end carries those microbes and the nutrients they produce.

The word is Turkish for long life, and kefir has been made for around 1,400 years.

What are probiotics?

Probiotics are the beneficial microorganisms that keep the balance of good microbes in your gut. They are already a natural part of your digestive system, helping break the food you eat down into vitamins and nutrients your body can use.

What does drinking kefir do for me?

It gives your gut a steady supply of probiotic nutrients, which is what helps your digestive system do its normal job well. Most people drink it daily for general gut health rather than for any one thing.

Scientific studies have linked kefir to a number of more specific benefits.

I am lactose intolerant. Can I drink milk kefir?

The microbes digest most of the lactose during fermentation, so it is usually fine. If you have a true milk allergy rather than an intolerance, choose water kefir instead.

Is it safe for children, and is it halal?

Yes. Our water kefir, milk kefir and Super Shots are halal, and Super Shot Kids is made for young children: no added fizz and milder than the adult shot.

Why does the label list sugar, if there is no added sugar?

Fermentation runs on sugar. The culture has to eat something, so cane sugar goes into the water kefir and the Super Shots, and a little into the kimchi. We list it because it genuinely goes in.

The microbes then eat almost all of it. What is left in the finished bottle is a trace of glucose and fructose, under 1.5%. Any sweetness you taste is that leftover, not a sweetener.

So when we say no added sugar, we mean nothing is added after fermentation. What is on the label went in at the start, to feed the culture.

Can you ship outside Jabodetabek?

Yes. We deliver anywhere in Indonesia, packed with an ice gel pack so it arrives cold, and the cost is calculated at checkout from your address. There is nothing extra to arrange.

Outside Indonesia we cannot ship at all yet.

How much should I drink a day?

Start with half a bottle in the first week, then one to two bottles a day. Best on an empty stomach, before a meal or about two hours after.
