For a batch to go out it must be full cooked and ready to smoke.
This magic number happens around the 30-45 day mark with daily cooking.
When the container reaches 25% mark. We then take the next batch and add it to the existing 25%.
Two things happen here.
1. You are seed Steeping between batches.
2. There is no sudden and drastic change in the flavor between batches.
When a new batch is started. We take 10-25% of the running batch and add it to the new batch. Again for seed steeping.
Once the flavors are considered ready to consume. They go out. But you will notice that the flavor undergoes subtle changes even when its with you. This is because it continues to evolve. Its not because its not steeped or because it needs to steep. Thats just the way it is with flavors.
