I'm new here and I was hoping to get some insight. This is the first time ive ever did a yeast starter. I boiled 2 cups of water with 1/2 cup DME for 15 min. Upon cooling it in an ice bath I noticed stringy white strands floating around in the wort when I swirled it. Is this normal? Should I throw it out and not risk adding my white labs Belgian Ale Yeast?
