Stop buying $12 jars of sauerkraut at the shop. You can make it yourself for $1.50 per jar. Here's how, Aussie style.

Cabbage Prep: The No-Faff Way
Use green cabbage (not red). Wash, dry, remove outer leaves. Core it, slice into 1/8-inch strips. No fancy mandoline needed – just a knife. 1kg cabbage = 1 litre jar. That's 1 medium cabbage (Coles/Woolworths: $1.50/kg).
2% Salt by Cabbage Weight – Or Don't Bother
2.5% salt by weight. For 1kg cabbage: 25g salt. Use non-iodised salt only. Iodised salt kills the good bugs.
Australian suppliers (cheapest):
Aldi Pickling Salt (500g): $1.80 → 25g = $0.09
Woolworths Sea Salt (500g): $2.50 → 25g = $0.13
Don't use rock salt or iodised table salt. It'll fail.
# Fermentation Timing: How Long I Leave It on the Bench
I leave the kraut to work for 3–4 weeks at room temperature, 18–22 °C. No fridge while it's actively fermenting — a dark cupboard does the job. Once a week I crack the lid. Bubbles and that tangy smell mean it's tracking properly. White mould gets scraped off the top. Black mould? Straight in the bin, whole jar and all.
Practical tip: Pack cabbage down hard with your fist until liquid covers it. Use a clean glass weight (Aldi $3.50 for a 1L jar) or a small jar filled with water. If cabbage floats, it spoils.
Australian gear: Bunnings sells 1L Mason jars ($5.95). Sterilise in boiling water for 10 mins. No plastic – it leaches chemicals.
My Off-Grid Sauerkraut Method
I use cabbage, salt, and a jar—no fancy gear. It's cheap, keeps for 6+ months in the fridge without power, and saves me $100+ a year. Sorted.
⚠️ SAFETY WARNING: Working with electrical systems, structural modifications, or gas installations carries inherent risks. If you are not confident in your abilities, always engage a licensed professional.
It shows the exact salt‑to‑cabbage ratio for a red‑cabbage ferment and demonstrates a two‑jar pressing method that works with minimal equipment, giving you a no‑frills kraut you can start in under five minutes.— Jenny Mills
Kraut turned to slime? I ring a food microbiologist.
While many off-grid projects are achievable as DIY, certain situations require licensed professionals:
Electrical work beyond basic 12V DC additions — requires a licensed electrician
Structural modifications to buildings or load-bearing elements
Gas line installation or modification
Solar array installations above safe voltage thresholds
Any work that affects the structural integrity of your property
Always check local regulations and obtain necessary permits before commencing work.
