Brewing Kombucha

Kombucha has become a popular probiotic drink thanks to its tangy flavor and numerous purported health benefits. While you can purchase Kombucha at most grocery stores today, many people enjoy brewing their own at home for a fresher, less expensive alternative. However, in order to brew the best quality kombucha, it is important to follow the proper steps and use the appropriate equipment.

The Kombucha Brewing Process

Kombucha ferments sweetened tea using a symbiotic culture of bacteria and yeast known as a SCOBY. This living organism feeds on sugar and tea to produce the acids, vitamins, enzymes, and carbonation that give Kombucha its signature taste and health benefits. The basic brewing process involves:

• Making sweetened tea – Black, green, or herbal tea is sweetened with white sugar. The sugar aids fermentation.
• Adding the SCOBY – The SCOBY is added to the sweet tea and allowed to ferment, usually for 7-12 days.
• Flavoring (optional) – A second ferment with fruit juice or other flavors can be done to enhance the taste.
• Bottling the finished Kombucha – Once the desired tartness is reached, the Kombucha is bottled for drinking.

Equipment Needed for Kombucha Brewing

Having the proper equipment is key to brewing quality kombucha at home. The essential gear includes:

• Glass jars – A wide-mouth glass jar is ideal for the initial brewing vessel. Glass does not leach chemicals, can be fully sterilized, and allows you to monitor fermentation.
• Tightly woven cloth cover – A coffee filter, paper towel, or clean cloth secured with a rubber band covers the jar while allowing airflow.
• Bottles – Flip-top glass bottles are best for storing finished Kombucha. Avoid long-term storage in plastic.
• Siphon – Use a siphon to fill bottles without agitating yeast sediment.
• Thermometer – Maintain proper brewing temperature of 75°F to 85°F.
• pH test strips – Test finished Kombucha to ensure a safe pH under 4.5.

Proper equipment makes the difference between a successful batch and a spoiled kombucha. Invest in quality materials like Glass and keep everything meticulously clean. Follow the brewing basics with the right gear, and you’ll be sipping fresh homemade Kombucha in no time.

Can You Brew Kombucha in Plastic?

Kombucha is a fermented tea drink prized for its refreshing flavor and gut health benefits. When brewing Kombucha at home, choosing the proper fermentation vessel is key to both safety and successful results. Many wonder if plastic containers can be used or if Glass is the only route. There are pros and cons to consider when weighing plastic as an option. While plastic may seem convenient, it is not recommended, especially for the initial brewing process.

The Pros and Cons of Plastic for Kombucha Brewing

Plastic seems like an ideal kombucha brewing option in some ways:

Pros

• Inexpensive and widely available
• Durable and hard to break
• Lighter weight than Glass
• Transparent for easy fermentation observation
• Can be sealed tightly to control air exposure

However, there are significant drawbacks that make plastic a poor choice:

Cons

• Can harbor bacteria if scratched
• The porous surface makes cleaning difficult
• Chemicals like BPA can leach into acidic Kombucha
• May impart plastic flavors and odors
• Not oxygen impermeable like Glass

Overall, the risks of using plastic outweigh the benefits when brewing Kombucha. Improper fermentation and contamination become concerns, while the finished drink may take on unpleasant plastic-like tastes.

Why Plastic Should be Avoided for Primary Fermentation

The first fermentation phase when brewing raw Kombucha is the most crucial for growing the SCOBY culture and avoiding mold. This is when avoiding plastic is especially critical.

pH Level

The SCOBY ferments the sweet tea to reach a pH of 2.5-3.5, which indicates a safe level of acidity for consumption. However, these pH levels make the Kombucha highly acidic, which can leach chemicals like phthalates and BPA from plastic into the brew.

Oxygen Permeability

The SCOBY requires oxygen to thrive during primary fermentation. Glass allows more oxygen to reach the Kombucha, while plastic bottles are less permeable. Limiting oxygen can stall fermentation.

SCOBY Health

A healthy SCOBY results in the best quality kombucha. But plastic can inhibit SCOBY growth due to issues like leached chemicals, less oxygen, and potential mold due to surface scratches in plastic.
For a thriving SCOBY and reduced contamination risks, use glass jars or stainless steel for the initial 7-10-day ferment. After primary fermentation, transferring Kombucha to plastic for short-term flavoring and bottling is less risky. But maximizing Glass is the safest practice for end-to-end brewing.

While plastic seems a convenient and affordable option, Glass is the best choice when brewing Kombucha at home. Avoid plastic, especially during the active fermentation phase, for the lowest risk of contamination, off-flavors, stalled cultures, and harmful chemicals in your finished Kombucha. Use rigid, non-reactive glass jars for worry-free fermentation and bottling. Your SCOBY will thank you with potent probiotic brews.

Alternatives to Plastic for Brewing Kombucha

While plastic may seem like an obvious choice when brewing vessels for homemade Kombucha, it has drawbacks. Safety concerns and potential impacts on flavor make Glass and other alternatives preferable. Thankfully, many options for plastic are affordable and suitable for fermenting this probiotic tea.

Glass: The Gold Standard

Glass is considered the gold standard for brewing kombucha. Its advantages include:

• Non-reactive – Won’t leach chemicals or degrade from Kombucha’s acidic environment.
• Impermeable – Glass allows oxygen exchange needed for SCOBY growth while protecting the Kombucha.
• Transparent – Makes it easy to observe the brew and SCOBY.
• Durable – Proper care allows glass jars and bottles to be reused indefinitely.

The main downside is breakage risk. But overall, Glass perfectly suits Kombucha’s needs. Use canning jars, swing-top bottles, and other glassware meant for food.

Stainless Steel

Stainless steel makes another excellent kombucha brewing vessel with pros such as:

• Non-reactive – Won’t impart metallic flavors or toxins into the brew.
• Durable – Stainless steel won’t crack or scratch like plastic. Also impervious to damage from acids.
• Reusable – Can be cleaned and sanitized for repeated kombucha batches.

The cons are cost and inability to view the brew. But high-quality stainless steel, like food-grade brewing kettles, is a smart, non-plastic choice.

Ceramic

Unglazed ceramic crocks have traditionally been used for fermentation. Benefits include:

• Non-porous – Glazed ceramic won’t absorb brew flavors or organisms.
• Reusable – Can be cleaned for continuous kombucha brewing.
• Visually appealing – Ceramic fermentation crocks have a rustic appeal.

The porous nature of unglazed ceramic makes it harder to sanitize fully, so contamination risks increase. Use ceramic with caution.

Consider Glass, stainless steel, or ceramic over plastic for your next home kombucha brewing session. With the right non-plastic gear, you can ferment up fresh batches safely.

FAQ

How long can Kombucha stay in plastic while brewing?

Limit the brew time in plastic to 5-7 days. The longer the acidic Kombucha remains in plastic, the higher the risk of chemical leaching. If doing a second ferment for carbonation and flavoring, first brew kombucha in Glass, then transfer to plastic bottles for 1-3 days max. Avoid leaving finished Kombucha stored in plastic; glass bottles are best for storage. The safest practice is using plastic only when necessary and sticking to the shortest duration possible.

Does brewing kombucha in plastic affect the flavor?

Yes, plastic can negatively impact the flavor of homemade Kombucha. Plastics like PET and PVC can impart a plastic-like taste. Chemicals leaching into the Kombucha can also create unpleasant metallic or chemical flavors. Acids react with plastic, so avoid extended brewing periods, which heighten leaching and off-flavors. The porous nature of plastic also provides more surface area for yeasts and bacteria to adhere to, making washing and reuse more difficult. For best clean flavors, Glass or stainless steel are ideal vessels for brewing Kombucha at home.

Can I reuse plastic kombucha bottles?

It’s best not to reuse plastic kombucha bottles multiple times. Scratches and cracks develop in the plastic each time it is reused, allowing more opportunity for chemical leaching. Reusing plastic bottles also increases the chance of bacterial contamination, especially if the bottles are not thoroughly washed and sanitized between uses. For bottling kombucha, stick to swing-top glass bottles, which can be used indefinitely with proper care. If reusing plastic, limit to 1-2 additional uses and inspect carefully for signs of damage before each use.
