How to Adjust Sourdough Starter for High Humidity?

Understanding the Impact of High Humidity

High humidity can cause the starter to become over-fermentative, leading to an imbalance in the microbial ecosystem. This can result in off-flavors, an overly sour taste, or a starter that’s too active. In a high-humidity environment, it’s essential to monitor the starter’s activity closely and adjust the feeding schedule accordingly.

Adjusting the Feeding Schedule

To adjust the sourdough starter for high humidity, reduce the feeding frequency from twice a day to once a day or even every 12-18 hours. This will help slow down the fermentation process and prevent over-proofing. For example, if you normally feed your starter at 8am and 8pm, try feeding it only at 8am. This will give the starter less opportunity to over-ferment and become too active.

Using a Smaller Feeding Ratio

Another approach is to use a smaller feeding ratio, which involves using less flour and water when feeding the starter. This will help to slow down the fermentation process and maintain a healthy balance of microorganisms. For example, if you normally use a 1:1:1 ratio (1 part starter, 1 part flour, and 1 part water), try using a 1:0.5:0.5 ratio (1 part starter, 0.5 parts flour, and 0.5 parts water). This will help to reduce the starter’s activity and prevent over-proofing.
