Description

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.

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.

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

Better Yeast Starters
When combined with a stir plate great for making starters for most strength beers. High gravity lagers need a bigger flask or to do two step starter

Does Exactly What it is Supposed To!
High quality, handles wide fluctuations in temp changes well, which is what you really need from a starter flask.

Erlenmeyer flask does great job for yeast starters
I've been using these for years & this one from More Beer does the job. Tempered glass helps it last a long time, as long as I don't burn the bottom!

Good value
I bought 2 after I broke the one I had for years. Works as designed and the best price I found for this size.

Perfect size for a 5gal batch
If I'm doing a 10gal batch, I use two of these. Its definitely nice to be able to do starters in a single vessel and avoid additional opportunity for contamination by transferring to another vessel. Handles going straight from a boil on the stovetop directly into the freezer to cool down before pitching yeast.

Perfect for Starters
I was looking to start using a stir plate. This is what I needed! Good price and great shipping speed!
