Going to be doing a yeast starter tonight and was wondering if it is necessary to smack the pack and let it expand for a few hours before pitching to the starter. This is normally how I make my starters but was wondering if I could just directly pitch the contents without smaking it.
If you are making a starter (and you should), there is no reason to bother waiting for it to expand. Go ahead and ‘smack the pack’, though - There’s a load of yeast nutrients in the inner pouch that will benefit the starter.
