Sourdough baking has become a favourite pastime in New Zealand, and for good reason. Buying sourdough starter in NZ gives home bakers access to live, active cultures that create flavourful, naturally leavened bread without relying on commercial yeast. But if you’re new to sourdough, it can be confusing to know where to start and what to buy.

A sourdough starter is a living culture of wild yeast and lactic acid bacteria. When fed regularly, it becomes the foundation for bread with great texture, flavour, and digestibility. Using a high-quality starter ensures your loaves rise well and develop that signature tangy taste.

When choosing a sourdough starter in New Zealand, look for:

• Organic sourdough starters. This ensures no glyphosate, or unwanted chemical processing agents which impact the microbial activity. 
• Sourdough starters that are fed frequently and well looked after to ensure resilient flop-proof starters!
• Live or freeze-dried cultures: Both are effective, but live starters can provide a richer flavour and microbial diversity.
• NZ-made products: Locally adapted starters perform better in our climate and are more resilient.
• Clear instructions: Beginners benefit from a starter that comes with feeding and storage guidance.
