Water kefir for beginners: what to expect, from order to first glass
At a glance
Never made water kefir before? You are in good company: most of our customers had not either. It is one of the simplest homemade drinks to get right. Your Natural Probio grains arrive alive with a leaflet and a step-by-step guide; you set up your first jar on the day they arrive, and your first drink is ready the next day. The grains settle in over the first few jars, and within a week the routine is second nature. If a question comes up, our team answers.
Starting anything new comes with a few nerves. Will it be fiddly? How will I know it is working? What if I get it wrong? This page takes you through it in order, from choosing what to buy to pouring your first glass, so you know exactly what lies ahead.
Before you order
Pick your size. The 30 g pouch makes about a litre of drink a day, plenty for one or two people. The 60 g pouch makes about two litres, which suits a family or anyone who wants two flavours on the go. If in doubt, 30 g is the ideal size to start with.
Check your cupboards. A glass jar, a sieve, a clean tea towel or cloth and a bottle with a good seal: that is the full equipment list. There is nothing extra to buy.
Think about the arrival day. Your grains are alive, so it helps to be able to open the parcel on the day it comes. If you will be away, the pouch can wait in the fridge for a few days.
The day the parcel arrives
- Open the parcel
Check what is inside. A slightly puffed-up pouch is a good sign that your grains are alive.
- Read the leaflet
A couple of minutes with clear illustrations, so the first steps make sense.
- Set up your first jar
Water, sugar, a dried fruit, a slice of lemon and your grains. Cover with a cloth, and you are under way.
Your first week
Days one to three. Your grains are waking up after their journey. The drink may be a little less fizzy or a little sweeter than you expected: completely normal, and the guide says so. They find their rhythm within two or three jars.
Around day three or four. You start to see small bubbles rising in the jar, and the drink takes on its fresh, lemonade-like character. This is a good moment to try your first flavoured bottles.
By the end of the week. The routine has become a five-minute habit. You strain, bottle and start again without checking the leaflet. This is usually when customers write to tell us they had no idea it would be this easy.
Signs that all is well
Bubbles
Tiny bubbles rising through the jar: your grains are working.
A changing taste
The drink becomes less sweet and more refreshing. That is exactly what should happen.
The guide to hand
Every situation a beginner meets is in there, along with what to do.
Someone to ask
A photo of your jar and a few words: we will tell you whether all is well.
The worries everyone has
"What if I get it wrong?" It is genuinely hard to go far wrong with water kefir when you follow the guide. A jar that comes out a bit too sweet or a bit too sharp is simply put right the next day.
"What if my grains don't get going?" The activity of your grains is covered by a lifetime guarantee: if they stay inactive in normal conditions, we replace them at no cost. Our guarantee, in plain English.
"I'm too busy." Five minutes a day, and the grains do everything else while you get on with your life.
"I'm off on holiday next month." The guide shows you how to let your grains rest in the fridge while you are away.
"Will it taste odd?" Most people are pleasantly surprised: it tastes like a light, fruity lemonade. And you can flavour it any way you like, starting with our flavour ideas.
They started just like you
"To be honest, I was a bit nervous at first, but the instructions are incredibly clear, thorough, and easy to follow (the included booklet is an amazing guide if you're a beginner like me!)."
