Transporting a SCOBY in a plastic bag is possible, but there are some important considerations to keep in mind. Firstly, it is recommended to use a glass container for storage, as some people warn against letting a SCOBY come into prolonged contact with plastic. If a plastic bag is used, it should be clean, airtight, and preferably a ziplock bag to prevent leaks during transportation. The bag should also be kept out of direct sunlight and at room temperature. Additionally, the liquid containing the mother SCOBY is crucial, so ensuring that it doesn't dry out is essential. These guidelines will help ensure that the SCOBY stays viable during transport.

Transporting a SCOBY on a plane
Packing Your SCOBY:
Firstly, understand that airlines restrict the amount of liquid allowed in carry-on luggage, so it is best to pack your SCOBY and its starter liquid in your checked luggage. To minimize leaking, place your SCOBY and a moderate amount of starter liquid into a ziplock bag and seal it tightly. The liquid is essential to keep the SCOBY moist and healthy. You can also double bag it for extra leak protection.
Absorbing Leakage:
Wrap the sealed ziplock bag in a small towel to absorb any potential leakage during the flight. Then, place the wrapped bag inside a larger plastic bag and seal it again. You can also add a second towel for additional protection. Remember, Kombucha has a low viscosity and can easily leak due to air pressure changes during the flight.
Declaring at Customs:
When declaring your SCOBY at customs, it is advisable to label it as "kombucha starter culture" for personal, non-alcoholic home brewing. However, be aware that there is always a risk of delay or rejection, so checking with your specific border/customs office beforehand is recommended.
Upon Arrival:
Once you reach your destination, carefully remove the SCOBY and liquid from the bags and transfer them to a normal glass container with a cloth cover. This will allow them to breathe and recover from the transit.
Additional Tips:
- Keep your SCOBY out of direct sunlight during transport.
- Store the bottles upright to minimize leakage.
- If the liquid dries out, "feed" your SCOBY with room-temperature black tea and a tablespoon of cane sugar.
By following these instructions, you can safely transport your SCOBY on a plane and ensure it remains healthy and active.

Using a plastic bag for short-term storage
When it comes to short-term storage, a plastic bag can be used to store a SCOBY for a day or so. It is recommended to use a clean baggie and double bag it for extra leak protection. While some sources advise against letting a SCOBY come into contact with plastic for extended periods, a day or so in a plastic bag won't hurt it. It is important to keep the SCOBY at a moderate temperature and out of direct sunlight.
If you are using a plastic bag for storage, it is best to use an airtight bag to prevent the SCOBY from continuing to be active, which may cause the bag to bloat. Unopened SCOBYs in their original packaging will last indefinitely when stored at room temperature (70-80°F) and away from direct sunlight.
When storing a SCOBY in a plastic bag, it is important to eventually transfer it to a clean glass container, such as a bowl, a large glass, or a mason jar. Then, cover it with a breathable cloth, such as a coffee filter, and secure it with a rubber band. This will allow the SCOBY to breathe and stay healthy.
While it is possible to store a SCOBY in a sealed container, it is generally recommended to use a breathable cloth cover. However, leaving it in a sealed container for a short period, such as a few weeks, won't cause any harm. The longer it is left sealed, the more sour it will become, but this can be beneficial for creating supercharged starter tea for the next batch of kombucha.
Additionally, it is important to ensure that the SCOBY doesn't dry out completely. If the liquid evaporates, it can be "fed" with a cup of room-temperature black tea (without the leaves) and a tablespoon of cane sugar. This will help keep the SCOBY live and active.

Using a glass container for long-term storage
While a plastic bag can be used for temporary SCOBY storage, it is not ideal for long-term storage. For long-term storage, a glass container is recommended.
If you are storing your SCOBY for less than a month and a half, you can simply brew a new batch. However, for long-term storage, a glass container is recommended. You can use any size jar, but it should be large enough to hold all of your SCOBYs and their food. Wash the jar with hot water and soap, and then rinse it thoroughly to remove any soap residue.
Once your jar is clean and dry, you can add your SCOBYs. Over time, you can add more SCOBYs to the same jar, creating a "SCOBY hotel." This is helpful if one of your brews goes bad, as you will have backup SCOBYs for new batches. If you have too many SCOBYs for one jar, consider giving some away or making multiple hotels.
To feed your SCOBYs, fill the jar about three-quarters of the way up with a 1:1 mixture of sweet black tea and fermented kombucha. You can also use room-temperature sweet tea or some finished, unflavored kombucha. Cover the jar with a clean, tightly-woven cloth and secure it with a rubber band. You can also use an airtight lid, but make sure to replace it with a breathable cloth cover once in a while to allow airflow.
Keep your SCOBY hotel at room temperature, between 65-85 degrees Fahrenheit (18-29 degrees Celsius). Do not refrigerate your SCOBYs, as this can cause them to go dormant or grow mould. The longer you leave your SCOBYs in the jar, the more sour they will become, but this is perfectly fine and will result in supercharged starter tea for your next batch.

Keeping the SCOBY alive with fresh tea
When transporting a SCOBY, it is generally recommended to use a glass container, such as a mason jar, rather than a plastic bag. However, for short periods, such as during transportation, a plastic bag can be used temporarily. It is best to double bag it for extra leak protection and keep it out of direct sunlight. As soon as possible, transfer the SCOBY to a clean glass container and cover it with a breathable cloth or coffee filter secured with a rubber band.
To keep your SCOBY alive and active, it is essential to provide fresh sweet tea regularly. SCOBYs can be stored in a "SCOBY hotel," which is simply a glass container with some room-temperature sweet tea or unflavored kombucha. Here are some tips for maintaining your SCOBY hotel:
- Use a glass container: A glass jar or brewing vessel with a tight-weave, breathable cloth cover is ideal. An airtight lid can also be used but is not necessary.
- Room temperature: Keep your SCOBY hotel at room temperature, ideally between 65-85 degrees Fahrenheit. Cold temperatures can cause the SCOBY to go dormant and put it at risk for mold.
- Feed with sweet tea: If the liquid level decreases, "feed" your SCOBY with fresh sweet tea or unflavored kombucha. A simple recipe is to steep 1 teaspoon of black tea in 2 cups of water with 2 tablespoons of cane sugar, then strain and allow it to cool before adding to the SCOBY hotel.
- Avoid flavorings: Avoid using flavored or herbal teas, as they can degrade and weaken your SCOBY over time. Stick to "real" tea, such as black tea, for the best results.
- Check regularly: While SCOBY hotels can go untouched for months, it is a good idea to check on them every few months to ensure the liquid has not dried up and the SCOBY is healthy.
- Keep the yeast: The brown stringy yeasty bits on your SCOBY are important for creating carbonation, so do not try to clean them off. Only remove some of the yeast if there is an overgrowth.

Transporting a SCOBY by car
Next, you will need to prepare the liquid. The liquid is just as important as the SCOBY itself, so handle it with care. Place the starter liquid and sweet tea into a separate, airtight container. You can use a glass or plastic container for this, but ensure it has a tight-fitting lid to prevent leaks. It is also a good idea to wrap the container in a small towel for extra protection.
Now, you are ready to pack your SCOBY and liquid into your car. Place the jar containing the SCOBY in a secure area of your car, such as the back seat or the trunk. Make sure it is well-padded and won't roll or slide around during the drive. Keep the jar upright and try to minimise any sudden movements or bumps that could cause leaks.
For added protection, you can also place the jar in a box or container and surround it with other items to keep it still. Keep the jar out of direct sunlight and maintain a moderate temperature during transport. If you are travelling a long distance, consider bringing extra tea and sugar to "feed" your SCOBY if needed.
By following these steps, you can safely transport your SCOBY by car and continue brewing your kombucha at your destination.
