Making my Imperial Pumpkin this weekend (OG 1.073) so I made a starter Tuesday evening. I like to pitch between 0.75 and 1.0 M/mL/P so I make a 2.5L starter on my stirplate and used 250g of DME. I am using WLP007 Dry English Ale yeast, which I have used in the past. In the morning the starter looked normal, but when I got home the yeast had flocculated out and were just being pushed around by the stirplate. By my estimate, the starter finished in about 18 hours when normally they take about 36. Should I be concerned or RDW...?
