Need to make 2 starters, only one stir plate

I have done what you suggest a couple of times, never had any problems. You can leave the first starter at room temp for an extra day if you are worried about it finishing in 24 hours, then crash both at the same time.

 

Yeah you're fine, proceed as you have planned

 

. . . or you could teach your yeast to share:

 

First-world brewing problems! Your approach is fine. Or, make both at the same time and rotate them on-off on the stir plate as suggested above. Or, just pick one up and swirl it whenever you walk by. If you're only pitching each starter into 5 gallons? Any of the above will work fine.

 

Shake and bake. I do it all the time. Honestly, if you aren't doing a huge beer you will be fine.

 

2 or 3 2 liter bottles, rinsed and sanitized. Less yeast in more wort is usually a better thing on a small scale.

 

Psh, 2 smack packs and you're done.

 

Two flasks and a receptacle wall plate made from granite.
Some people have everything for their brewery.

Even a little time in a starter solution will wake up the yeast if not multiply cells. You don't need too much for 1051. Making a starter, even with an older vial, is probably not required but certainly a good idea. I might just worry about the expired yeast and pitch the other fresh.

Cheers.

 

I just bought my first stir plate today and have made over 20 starters without it. sooooo I think you will be ok without. or just rotate.

 

. . . I'm more proud of having 20 amp circuits. Okay, you really don't need a 2000 watt stir plate, but you never know when you may have to run an air compressor or do some arc welding in the kitchen:

 

The thread Title sounds like a video i watched for about 20 seconds.

 

In the past, I've tried to shut my stir bar up. Too loud. I collapsed an empty 6er box on top of the plate and underneath the flask. It was quiet. The magnet was likely to get thrown off. Maybe you'll have better luck? Change can't always be bad.
