We started making kombucha at home at the beginning of the year, and it was so simple (and saved us so much money!). Luke and I have a bit of a kombucha habit. So when we decided to move into the RV and travel full-time, I knew I had to figure out a way to brew kombucha in the RV.

This simple guide to making kombucha is a fool proof way to make kombucha at home with a few tips at the end for those of you wanting to brew on the road.

Simple Guide to Making Kombucha

What you need to get started making kombucha…

You will need right a way:

  • Gallon glass jar with a secure plastic lid
  • Cheesecloth and a rubber band
  • 14 cups of distilled/purified water
  • 8 bags of black tea or green tea
  • 1 cup of sugar (I prefer organic cane sugar)
  • Scoby culture – you can buy one, get one from a friend (or me – I have plenty) or if you’re really intense make your own
  • A few tablespoons of apple cider vinegar
  • A wooden spoon

Everything you need to make kombucha at home

You can also buy a kombucha starter kit like The Complete Kombucha Kit that comes with everything you need. It’s what I used to get started because I knew it’d take me forever get everything together.

You should go ahead and get:

  • Glass bottling jars – something like this: 16 Ounce Clear Bottles or recycled store bought kombucha bottles
  • Funnel
Step-by-step guide to making Kombucha
Making Kombucha at Home

Step 1: Boil 8 cups of water
Step 2: Remove from heat and add the tea bags; steep for 6-8 minutes
Step 3: Stir in the sugar until fully dissolved
Step 4: Pour the tea mixture into your gallon jar and add the remaining water; leaving 3 inches of space at the top of the jar (unless you’re traveling in an RV*)
Step 5: Allow the tea mixture to cool to room temp – don’t kill your scoby by putting it into the tea too soon
Step 6: Clean your hands with vinegar and water (not soap) – make sure they are really clean
Step 7: Gently pick up your scoby and add it to the tea mixture in the jar
Step 8: Stir in a few tablespoons of apple cider vinegar using a wooden spoon. You want the pH at 4.5 or below. I don’t have pH strips, so I just do 2-3 TBS – it works just fine.
Step 9: Place the cheesecloth over the jar and secure with a rubber band
Step 10: Place the jar somewhere dark that has a bit of ventilation – I’ve found the cabinet to work just fine. Try not to move it until it’s done.*
Step 11: Wait 1-3 weeks.

Complete guide to making Kombucha

Wait 1-3 weeks? Not super specific, huh? The hotter the climate, the faster the fermentation. You may only need 7 days. The colder the climate, the longer it will take. I once had one take 3-4 weeks to finish. (RVers, be sure to read the notes at the bottom on this.*)

After a week, using a WOODEN spoon (no metal should touch your booch), begin tasting your brew. If it’s still sugary sweet, it’s not quite ready. If it’s too bitter, add a tablespoon of sugar and give it another day or two. You can also tell when it’s ready by the baby scoby forming on top of the jar or as a layer on your original scoby. Once it’s sizable enough to pick up, you’re probably done.

Final step: With clean hands, remove the scoby and place it in a shallow tubberware (or start a scoby hotel) with 1 cup of the kombucha. This will be your starter for your next batch.

How to Make Kombucha at Home

That’s all there is to the first fermentation. To add flavor and fizz, here’s how you do the second fermentation.

Making Kombucha in an RV*

Alright fellow full-time RVers, making kombucha on the road isn’t difficult, but there are a few things to be aware of.

  1. I don’t fill my jar up with the additional water as much as I did at home. I leave about 4 inches at the top versus 3 inches.
  2. You don’t want to move too much during the first fermentation. Kinda problematic when moving in your lifestyle, right? Here’s how we handle it:
    1. I avoid making a new batch if we’re going to move several times in the next 1-2 weeks. Just wait until your settled. If we’re only moving once or twice, I go for it.
    2. The jar is only covered in cheesecloth. I place the jar in a plastic grocery bag with a small towel, just in case there is any splashing or spillage on travel day.
  3. Find a secure, dark cabinet to brew your kombucha in and make sure it’s secure on travel day.
  4. Temperature control. This is difficult. We’ve gone from cool 40-50 degree weather to hot 90 degree weather in a matter of days. When it’s cold, I wrap the jar in towels to keep it insulated. When it’s hot, I just keep checking it since it will be done brewing a lot faster.
  5. Have fun with it. The different atmospheres and climates will alter your booch. Don’t be afraid to mess it up. Try new things until you figure out what works. With all the fresh, local fruits at different destinations, you can experiment with all sorts of flavors in your second fermentation.

If you have questions about the first fermentation, leave it in the comments, and I’ll be sure to answer it. I don’t want you missing out on this probiotic goodness.
