I created a yeast starter last night using ~200 grams DME, 1.80L Water and 1 flask of California ale yeast. I boiled the DME for 10 minutes in a pot and cooled to ~70 degrees. I also cleaned and sanitized the flask, dumped in the cooled wort, pitched and set it on the stir plate. This morning i looked at it, and noticed that there is a red/maroon circle of dots/specs that I'm not completely sure what they are. Any advice? I'm brewing tomorrow, so if i need to make a new starter, i'll need to do it as soon as i get home.
