Your Questions About Kefir Answered

How Do I Incorporate Kefir into My Diet?

Drink Directly: The simplest way is to drink it straight. You take Kerry Kefir like a supplement to your diet. It’s not normally used as a milk replacement. Beyond drinking, kefir’s culinary applications are vast:

Dips and Sauces: Mix kefir with herbs and spices to create tangy dips or creamy sauces.

Frozen Treats: Freeze kefir with fruits to make popsicles or use it in ice cream recipes.

Create smoothies: Kefir can be added as a liquid base to any smoothie

Marinades: Kefir’s acidity can tenderise meats, making it an excellent marinade base.

Overnight Oats: Mix oats, kefir, fruits, and nuts and let them soak overnight for a nutritious breakfast.

Use in Baking: It can be a great substitute for buttermilk or yoghurt in your baking recipes

We have a recipe section here if you’d like more inspiration. 

How Much Kefir to Drink?

If you’re new to traditional Kefir, we recommend starting with a small amount (100ml) and adjust based on how you feel. Taking small amounts of Kerry Kefir daily is far better than taking large amounts irregularly.

Our Recommended Daily servings are:

Adults and teenagers: 100-150mls

Under 12: 50mls

Under 2: 1-2 tablespoons 

(I don’t recommend drinking more than 250mls a day)

When Is The Best Time to Drink Kefir?

I take it first thing in the morning on an empty stomach, as I feel it sets me up for the day.While you can drink kefir anytime, many prefer having it on an empty stomach in the morning or before bed for maximum absorption. Both are perfect ways to take it, find what suits your routine and stick to it.

Is it safe to drink kefir every day?

Absolutely! Daily consumption may help maintain a healthy balance of gut bacteria.

Can I give Kefir to my kids?

Yes! Kids need good bacteria cultures just as much as adults do. It’s a brilliant idea to introduce kids to fermented foods early in life. 

Can Kefir Milk Be Heated?

While you can heat kefir milk, it’s essential to note that high temperatures can kill the beneficial bacteria. If you’re consuming kefir for its bacteria cultures, it’s best to avoid heating it. However, if you’re using it in recipes where the flavour matters more than the good bacteria content, like baking, heating is fine. You will still get lots of benefits from that were created during the fermentation process itself.

What Do I Do When My Kefir Gets Thick?

A Gentle Shake: A gentle shake can bring it back to a drinkable consistency. Try to avoid shaking vigorously as this can lead to carbonation and when you open the bottle you may experience the “Champagne of Milk”! – have a large jug or saucepan at the ready. 

Add Fresh Milk: If you feel it’s gone too far for your taste buds, you can add in a dash of fresh milk and give it a mix.This will mellow out the flavour for you to continue enjoying our kefir.

Stir In: Mix it into oatmeal, cereals, or use as a base for creamy sauces or dressings.

Blend It: Use it as a base for smoothies, adding fruits or vegetables for added flavour and nutrition.

Does Kefir go off?

Because Kefir is a fermented product, technically it doesn’t “go off”. It just continues to ferment in the bottle as the weeks go on. It will get thicker and stronger tasting, but it’s still perfectly safe to drink even up to a week after the Best Before date.
