The size and price
Is the bottom flat? The one i have from elsewhere doesn't and it is useless on my stir plate.
Ashton Guthrie on Mar 9, 2018
What size stopper fits this flask?
Kirk Slocum on Jun 28, 2018
BEST ANSWER: #10.5 is too big for this flask - I bought one and it didn't fit. a #10 fits just right.
Does is come with a foam stopper?
William Robbins on Jul 26, 2019
BEST ANSWER: It does not come with any stopper, but it is a great flask. Highly recommended. I also purchased the 5000 ml at the same time and wished I’d bought 2 of the 3000 ml for doing back to back yeast batches.
What high of the flask?
Viktor Vitishko on Oct 2, 2018
BEST ANSWER: the 3000ML is 12 and 1/4 inches high. Great flask!

Gets the job done!
Not much to say. It’s a nice big flask. For high gravity beers where you’ll want 2L of starter, this is a nice option because you can boil your wort right on the stove top in the flask and then stir by hand or put on a stir plate after it cools.

Bottom not flat
The flask does not have a flat bottom, which can be an issue with the stir bar sliding off. On a simple water test, the stir bar stayed in place; however, I have yet to try it with a starter.

On a more positive note, the flask arrived well packaged and in good condition.

Bring on the big stuff. Big beers or lots of beer this will allow you to make a big enough starter for a 10 gallon batch
Good quality thick glass which should hold up overtime. Let’s me do bigger starters.

NOT for use with a stir plate :(
The 3000ml flasks that are currently being shipped have a concave (not flat) bottom. If you intend to use a stir plate, this is not the flask for you. Otherwise, the flask I received is sturdy and without defects. Mike from Customer Service was professional and assisted me with the return.

Like it more than the 2000 no flasks
Perfect size for doing a starter. Gives more flexibility with the size of the starter needed!

Great size and well made
I used this to make a 2.4L starter and still had plenty of headroom. Note that a #10 stopper fits well, not a 10.5 as suggested in the Q&A section.
