Relatively new starter; maybe 3 weeks into it. Feeding now consists of 25g-50g-50g starter, flour, water. It now raises 1.5x in size every 12 hours and has a ripe fruity aroma. Feeding is done every 24 hours. At this stage, how much longer should I continue daily feeding until it has a nice bready and yeasty aroma?
You're good on the yeast activity. Your feed ratio is pretty high at 80%, a lot of fresh flour, lower it to 50-60% and feed less often, every 2-4 days.
