What yeast strains are allowable, is it just the usual suspects ie dried yeast available to micros (nottingham/S04 etc) or can for instance non-seasonal whitelabs/wyeast/brewlabs strains be used.[/quote:2ojox3xa]
We're using dry yeast at the moment. I haven't tried scaling up a liquid yeast starter to full scale yet. Dry yeast would keep it simple.
