When home brewing beer what will happen if the sediment strained when pouring it from pot to fermenting container is a bad thing?

Leaving sediment in your beer when transferring it to the fermenting container is generally not harmful and can even be beneficial. This sediment is mostly composed of yeast and other proteins that help to clarify the beer as it ferments. However, if you are worried about the appearance of your beer, you can carefully pour it off the sediment or use a racking cane to transfer the beer without disturbing the sediment.
