I just use a magnet taped to a piece of paper (so I don’t lose it). Then when I go to pour the yeast, I put the magnet on the bottom of the flask to keep the stir bar in the flask and pour away.
I do the same with a magnet on the bottom. If I needed to get the stir bar out without decanting, I would use the magnet to pull the stir bar up the side and out.
I do the magnet thing on the bottom of the flask also. Learned my lesson when I dumped out a starter into the toilet. I have a stir bar attached to the cast iron pipe somewhere inside the waste line. Not fishing that one out.
I just grab a magnet off the refrigerator and use it to pull the stir bar up the side of my gal. jug from the outside. It’s kinda like a stunt on a game show…
I use a 3.5L cookie jar from the Wal-Mart. Cost me $4.88 as opposed to the $25-$30 Pyrex flasks I kept breaking. That this has lasted me nearly a year now!
For lagers it’s usually a 1 gallon jug for me. Otherwise it’s one of my fermenters with about 2.5-3 gallons of “starter”. Those are much tastier without a stir bar ;D
I think a lot of good beer has been made without a stir plate. That being said, I value mine pretty high. I think it’s number three behind sanitation and fermentor temp control
If I were handy, I could make a stir plate. I bought one at www.stirstarters.com. It was only $45, including shipping. Lifetime guarantee. I had a starter overflow and yeast got into the unit. It was fixed, no charge, even though it was clearly my fault. Can’t say enough about the customer service.
Do you mean the ones that use the 500 gram bricks? Or that buy pitchable quantities for big $$$. Some just harvest and repitch after they get a yeast going. Some go a long time with a culture, hundreds of pitches.
Many of the larger ones have yeast propagators, which aerate and mix the yeast. Can’t do those on a stir plate.
