If you find making yeast starters necessary than this tool makes that task a whole lot easier. Right size for the 5-10 gallon batch size. Combo this flask with a stir plate and you be styl’n!

True to the Erlenmeyer name. Cooks over flame without cracking and holds yeast well with in airlock on top (airlock not included)

For 5gal batches, I recommend going with the 2000ml version instead, which is large enough to reasonably handle a 1500-1600ml volume starter, and still minimize boilovers on the stove top so long as you watch it closely near boil time and are quick to reduce the heat at the transition point.

This flask is great for small yeast starters. Also if you have it shipped Morebeer packages it so well, there is no chance of it breaking.

I have been brewing for a few years when I decided to move up to increasing the effectiveness of my yeast. The 1000ml flask is great for this. It insures enough yeast for a robust fermentation.

This product is great because you can fill it with boiling liquid, and place it in an ice bath (as long as the ice bath water surface line does not go over the surface line of the liquid in the flask). One piece of advice for anybody who plans on advancing their brewing skills- get the 2000ml flask. For a lot of beers the size of the starter required with exceed 1000ml. I've had to make more concentrated starters as a result. I don't know how people who purchase the 500ml do anything. You can always just do successive starters, but just be easier on yourself and go for the 2000ml.
