I'm with Bengelbrau. When my wort is cooled, I decant the bottom of the pot into several pitchers, place them in the refrigerator and save the top wort. Everything else settles to the bottom. I freeze the wort in pint or qt containers and never run out for starters. If my wort is 1.048 I add 50% water to make it 1.024 when it's time to make my starter. Why spend money on expensive DME.
