Simple device works as expected. Works great making starters for up to five gallon batches

This flask is the perfect size and material with which to make a five gallon yeast starter. Convenient to use as the glass can go right on the open flame stove. Quality is excellent.

Excellent quality. Nice that you can boil directly in the flask

I have also used this to mix additional nutes and add them after fermentation has begun.

This vessel worked very well and the size was prefect for my Yeast Starter and Magnetic Spinner.

Well it does hold what it says. I don't boil in them so can't say. It scares me to put on flaming stove top. Base may be too large for some stir plates. 2000ml base 4.75''- 5'' w

I have used this flask twice now to do a yeast starter for homebrewing beer. I have been able to use the flask directly on a stove top burner and directly cool in an ice bath. I also use a stir plate and it works great. There were some other comments that the curved bottom inside the flask prevented the stir bar from staying centered. I have not experienced that; the bar has remained in place and continued to create a nice vortex in the wort.

I've made a starter with this on a stir plate and it worked fine. Looks like it will be easy to clean with a bottle brush.

Well made. Nice smooth bottom as to not throw stir bar. Works well with water now to throw a starter in it and see how it does.
