I am just starting out. Brewed a couple of batches ad-hoc, now trying to learn. Reading how to brew. A dumb question, when calculating required water it is mentioned that the contraction of water when it cools off can be added in to the calculation.
If you are measuring using tap water that is pretty cool, doesn't the water expand and then contract back down again? So why would you need to make any adjustment for this?
