If I make a starter, I have no stirplate can I put an aquarium pump line in and just areate in place of a stir plate? Keeping it sanitary of course with foil over the top. The bubbling taking place of the stir plate?
I just brewed two different beers using a yeast starter on both. You can swirl bottle or flask around to rouse the yeast and aerate. Both starters were different yeast and after I pitched the starters I got furious fermentation within 10 hours.
