DIY Fermentation Basics: Equipment, Ingredients & Safety

  Essential Equipment & Supplies Clean Jars & Fermenting Vessels: Wide‑mouth glass jars or ceramic crocks—avoid reactive metals. Weights & Airlocks: Non‑reactive glass or food‑grade plastic weights keep solids submerged; simple airlock lids or cloth covers prevent dust while allowing gases to escape. pH Strips or Digital Probe: Optional, but helpful for checking acidity (target pH ≈ 3.8–4.5 for lactic ferments). Key Ingredients & Starter Cultures Salt: Non‑iodized sea salt or pickling salt at 2–3% weight of produce (roughly 1 Tbsp per 1 lb). Sugar & Tea: For kombucha, use plain black or green tea and ½ cup cane sugar per quart of brew.
