How much headspace do I need for fermentation?

Active wine/beer fermentation needs 20-30% headspace due to CO2 foam. Lacto-fermentation (kimchi, sauerkraut) needs minimal headspace if kept submerged.

What vessel materials are safe for fermentation?

Food-grade plastic, glass, ceramic, and stainless steel are all safe. Avoid regular plastic containers not rated for food use; metals other than stainless can react with acidic ferments.
