Buying Guide: Fermentation Kits for Beginners
Here’s what to consider before choosing your kit:
1. Jar Size
1-gallon jars are beginner-friendly. Larger jars are better for families or bulk ferments.
2. Airlock System
Airlocks keep oxygen out and good bacteria in. They’re a must-have for consistent results.
3. Fermentation Weights
Weights keep food submerged in brine. Without them, you risk mold.
4. Extras
Recipe books, starter cultures, and multiple jars add value, especially if you’re brand new.
