Kit

The complete vegetable-fermentation kit

Eight things, in the order you'll meet them — with the real reason for each, the two that keep your ferments safe, and nothing padded in to fill a list. Whether you're starting your first jar of kraut or shopping for someone who is.

Every tool below links straight to Amazon — in the order you’ll actually meet them, with the honest reason each one earns its spot and which ones you can skip.

The eight essentials

  1. 1. Digital scale, 0.1 gBuy first
    Start here. Salt percentage is by weight, so every number on this site assumes grams. A 0.1 g scale is what makes a “2% brine” actually 2% — the line between a safe ferment and a guess.View on Amazon →
  2. 2. Wide-mouth glass jars (quart + ½-gallon)
    The vessel. Wide-mouth jars let you pack cabbage by the fist and still fit a weight and an airlock on top. A quart for a first test batch, a half-gallon once you're hooked.View on Amazon →
  3. 3. Glass fermentation weightsSafety
    Keep everything under the brine. Submerged vegetables ferment safely; anything poking above the line grows mould. The cheapest insurance against tossing a whole jar.View on Amazon →
  4. 4. Airlock fermentation lids
    Let CO₂ escape while keeping oxygen — and fruit flies — out. Wide-mouth lids that fit standard jars, so you ferment hands-off instead of “burping” every day.View on Amazon →
  5. 5. Pickling / fine sea salt
    Pure salt — no iodine, no anti-caking agents. Both fight the bacteria you're trying to grow and cloud the brine. This is the salt the percentages on this site assume.View on Amazon →
  6. 6. pH test stripsSafety
    The objective safety check. A finished ferment should read below pH 4.6; strips turn “is this safe to eat?” into a number you can actually read.View on Amazon →
  7. 7. Stoneware fermentation crockOptional
    The heirloom upgrade. A water-sealed crock with built-in weights handles 5 L+ of cabbage at once — pack it, fill the moat, and walk away for weeks.View on Amazon →
  8. 8. Kitchen thermometer
    Fermentation speed is almost all temperature. Knowing your room sits at 18 °C versus 24 °C is the difference between a 5-day and a 12-day kraut.View on Amazon →

🎧 Prefer to learn the craft by ear?The numbers here are the what; the books are the why. Sandor Katz's The Art of Fermentation is the canonical reference, and Michael Pollan's Cooked tells the best story there is about why a jar of cabbage comes alive. An Audible trial gets you either — and it supports this site more than a dozen gear clicks do.Start an Audible trial →
