What is the difference between batch sparge and continuous sparge?

Batch sparge involves adding all the sparge water at once after the initial mashing process. This method allows the grain bed to be flooded with water, which helps to extract sugars from the malt effectively in one go. Once the water is added, it is then drained from the mash tun, allowing for the sugars to be collected in a single step rather than more incrementally.

In contrast, continuous sparging involves adding sparge water slowly and gradually during the draining process. This technique maintains a consistent level of water over the grain bed, which can enhance the extraction process but may take more time to complete.

The other options do not accurately describe the processes involved in batch and continuous sparging.
