Can I use Coopers dry ale yeast for a light honey lager (OG 1.048-1.052) brew? I am currently planning on a Cal. lager yeast but the starter is on the old side (9 days in frig) and I'm worried they might not ferment.
Yeah, you can, but it obviously won't be a lager. It'll be an ale, and will still be good beer, but you should ferment it at ale temps (64-70 F) instead of at the cooler lager temps.
