The perfect container for rehydrating yeast or mixing up additions. Erlenmeyer flasks allow you to swirl your yeast or acid, tannins, nutrients, etc. into solution. The clear glass allows you to see when the solution is fully mixed.

In the lab world, these are known as "Student Grade"

Made from Borosilicate glass, it can be rapidly heated or cooled without the risk of cracking.

Recommended Process for Use of Flask:
Double Boiler Method

It is important for your safety to heat water in the flask with a heat source that distributes heat evenly. Our manufacturer has confirmed that direct heat to the glass can break down its integrity and break if the heat source doesn't distribute evenly.  Morebeer! recommends using the "double boiler method."  This process involves using a boiling water bath on the outside of the flask to heat up the water inside the flask.  All you need is a kettle 3 gallons or larger.  This process is much safer and efficient. If the flask should break or boil over, your kettle will be there to collect the contents, thus keeping your stove clean and keeping you away from potential harm.  

  • Massive 2L (2000ML) Capacity
  • Made from Borosilicate Glass
  • Fantastic price for a flask of this size
  • Produced for MoreWine!

Nicer than expected.
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.

fair price for good product
Sturdy construction for heating on stove. Only challenge is finding a bung/stopper to fit for airlock.

Bottom not flat
I'm guessing that at least 50% of home brewers use a stir plate when making starters. These flasks are unsuitable for that purpose because their bottoms are not flat. They are curved and cause the magnetic capsule to throw to the edges of the flask. In all other respects they are sturdy and useful, but if you have a stir plate, you will be very disappointed.

Quality Product
Love this flask, it's very thick and well made. No issues heating to a boil directly on a gas stove.

Works as advertised, great size for a large starter, which is great for higher gravity beers. Shipping was quick and easy!
