Whether you’re fermenting your first batch of sauerkraut or levelling up your kombucha craft, a reliable fermentation tools list is your best kitchen ally.

Home fermentation is about more than just jars and salt. From keeping your workspace clean to optimising airflow and tracking pH, a well-rounded probiotic equipment kit ensures consistency and confidence. This article walks you through the essential and nice-to-have home fermenting gear, including real-life use cases, product tips, and how each item supports your success.

By the end, you’ll know exactly what tools you need (and what you can skip), so you can spend less time second-guessing and more time fermenting delicious, gut-boosting foods and drinks. Let’s dig in.

Essential Tools for Every Home Fermenter

1. Glass Jars (Various Sizes)

Why You Need Them:

• Transparent, non-reactive, and easy to clean
• Perfect for small batches, visible bubbling, and safe storage

Recommended Sizes:

• 250ml for pastes or starter cultures
• 500ml–1L for vegetables or condiments
• 2L+ for kombucha or bulk batches

Pro Tip: Use wide-mouth jars for easier packing and cleaning.

2. Fermentation Weights

Why You Need Them:

• Keep food fully submerged in brine
• Prevent mould and ensure anaerobic conditions

Options:

• Glass disc weights
• Ceramic or stone
• DIY: Small water-filled zip bags

When to Use:

• Lacto-fermented veg (e.g., kimchi, pickles, kraut)

3. Airlock Lids or Fermentation Tops

Why You Need Them:

• Let CO2 escape without letting air (or bugs) in
• Reduce chances of spoilage

Types:

• Water airlock lids
• Silicone vented tops
• One-way plastic lids

Alternative: Loosely screw regular lids (but remember to burp!)

4. Non-Iodised Salt

Why You Need It:

• Iodine and anti-caking agents can interfere with fermentation

Best Options:

• Sea salt
• Himalayan pink salt
• Pickling salt

Use With:

• Sauerkraut, brined veg, ferments that require salting

5. Mixing Bowls (Non-Reactive)

Why You Need Them:

• Useful for salting, massaging, or mixing your ingredients

Materials to Use:

• Glass
• Stainless steel
• Ceramic

Avoid:

• Aluminium or scratched plastic (reactive surfaces)

6. Funnels (Wide-Mouth Recommended)

Why You Need Them:

• Transfer chopped veg, brine, or liquids without mess
• Protects jar rims and helps avoid waste

Materials:

• Stainless steel or food-grade silicone

Ideal For:

• Kombucha bottling, pickle jar filling

7. Wooden or Silicone Pounder (Tamper)

Why You Need It:

• Compact vegetables tightly into jars
• Release liquid from shredded ingredients

Popular Uses:

• Sauerkraut, kimchi, beet kvass base

Additional Tools That Make Fermenting Easier

8. Digital Kitchen Scale

Why You Need It:

• Fermentation is a ratio game
• Salt concentration must be precise (typically 2% by weight)

Must-Have For:

• Beginners and anyone scaling up batches

9. Thermometer

Why You Need It:

• Temperature affects microbial activity
• Ideal range: 18–22°C for veg, 24–28°C for kombucha/kefir

Type:

• Instant-read digital thermometers are easiest

10. pH Strips or Meter (Optional but Helpful)

Why You Might Want It:

• Confirms safety (most lacto-ferments should drop below 4.6 pH)

Use Case:

• Experimenting with unusual ingredients or long ferments

11. Clean Labels or Washi Tape

Why You Need Them:

• Track start dates, recipes, and variations

Best Practices:

• Label every jar with contents and date
• Use a colour code if managing multiple ferments

12. Fermentation Log Book

Why It Helps:

• Note what worked (and what didn’t)
• Record environmental conditions, ratios, timings

Great For:

• Learning faster and scaling confidently

Personal Story: Setting Up My Ferment Corner

“When I started, I had just a jar and some salt. Within months, I had a whole shelf with labelled jars, a logbook, and three types of lids. Now I keep a fermenting station with everything in one spot. It saves time and lets me get more creative with each batch.” – Jess, fermenter for 2 years

Troubleshooting Gear-Related Mistakes

Jar explodes or leaks?

• Too full, or lid sealed too tightly (use airlock)

Cloudy brine or floating food?

• No weight; food is exposed to air

Mould on top?

• Use airlocks and ensure clean tools

Salt didn’t dissolve?

• Try fine-grain salt and stir with warm water
