Making a yeast starter is essential for proper pitching rates and reducing lag time when fermentation begins (this greatly minimizes the chances of bacterial infection in your batch). Starters will supply more yeast than your standard vial or package. Our large 2000 ml (2L) Erlenmeyer Flask is the ideal vessel to make a yeast starter for 5 gallon batches, even for lagers and high gravity brews! This flask is made from borosilicate glass, which means it can be moved from a boil on your gas stove to a cold water bath for cooling, without the risk of cracking. (We do not recommend the use of an electric element. If this cannot be avoided, we recommend using a larger pot as a hot water bath on the stove.) With flasks, your yeast starter process can be completed all in one container. This not only keeps things simple, but the fewer the containers, the less risk for contamination.

Why make a yeast starter?
Yeast starters ensures healthy yeast. By creating a yeast starter 1-3 days in advance of your brew day, you ensure that your yeast is healthy and strong enough to do its job. Secondly, the starter creates more yeast. This increase of the cell count will give you a better chance of keeping bacteria's and wild yeasts from fermenting in your wort. If you are planning to brew a high gravity beer (1.060+) you will need more yeast to start the fermentation faster. High gravity beers will also have a better chance of completing fermentation with ample quantities of yeast (less chance of stalling out).

Glass Erlenmeyer Flask (2000 ml)

Recommended Use of Flask:
The "Double Boiler" Method. This involves using a boiling water bath on the outside of the flask to heat up the water/wort on the inside. All that is required is a kettle 3 gallons or larger. This is a safer and more efficient process. If the flask should ever break or boil-over, your kettle will be there to collect the contents keeping your stove clean and you away from potential harm. This method keeps the heat distribution even throughout the flask. Direct heat, non-even heat distribution, to the glass can break down it's integrity over time.

  • 7" Base, 2 1/4" Top, 11 3/8" Height
  • 2L (2000ml) Capacity
  • (Fits a #10 Rubber Stopper - Not Included)


In the lab world, these flasks are known as "Student Grade". A great flask for making yeast starters! (Student grade is not the highest grade flask and will have minor defects).)

4 of 5 Good Erlenmeyer July 28, 2017
Reviewer: Guy Labbé from Québec  
I heat it directly on a glass stove and let it chill to the room temperature afterwards. I used it a few times (~10), had no problem so far. I am not sure this is the safest way to use it, at this price, you should take some precautions, such as boiling your starter in another vessel and then pour it back in the erlenmey. Still, this is very good for the price. The bottom is flat so it will stand by itself and it will allow you to use it with a stir plate. Enjoy!
