It appears the method of “shaking” the starter instead of using a stir plate is still quite significantly better than doing nothing at all.
So what exactly is expected to get these results on most calculators? How often should I shake? I’m out of the house 10+ hours a day and sleeping another 6 so I can’t give it a shake every hour or so.
My dilemma is I wanted to brew this weekend and need quite a starter (1.090 target OG). My stirrers for my stir plate have not arrived yet cause apparently they take 1.5 weeks to ship from TX (pretty sure i can ride my bike there in that time…ok maybe not). The date on my yeast i received yesterday is 08/28 which puts its viability at 66%. It appears on most calculators creating 1.5L starters I can get there with a 2 step starter using the “shake” method but without it, i cant even get there with a 3 step starter.
The other option is, i wait till I get my stirrers and brew the following week. Not nearly as fun
