So the advantage of an Erlenmeyer is that it has a narrow neck so which reduces the risk of contamination.

I'm going to save $10 and use a Mason jar with a bit of flame-sterilized Aluminium foil over the top. Might even be legal in Texas.

Unless you all can persuade me otherwise

The erlenmeyer also has a nice flat bottom that won't throw the stir bar. Sometimes it's hard to get the stir bar to stay put in a jar/jug.

I use a Simply Orange plastic 63ish oz jug. Works just fine.

Simply Orange? I don't drink stuff like that, it looks almost healthy.

I am not persuaded, try harder

The nice thing about a Erlenmeyer is it looks cool. The advantage is that you have less boil off because of the narrow neck and you can heat and chill in the same container and it does hold a stirbar. I tend to boil my starter in a saucepan and transfer to a Erlenmeyer if I'm doing less or equal to a 1 liter starter since my largest Erlenmeyer is 2 liter. When I make a larger starter I use a 1 gallon pickle jar or if larger you can use a plastic storage container. Just look around the house or store for an appropriate container. The disadvantage to the saucepan method is you will have more boil off due to the larger surface area. But you just take it into your calculations.

Erlenmeyer can go from stove to ice bath without exploding, and has accurate measuring marks.

Edit: Dont take my word for it regarding exploding. I may be wrong, see below.

The advantage of a Erlenmeyer, as nm999 pointed out, is the flat bottom that lets you spin stupidly large stir bars without stupidly powerful magnets.

Also, you can boil and chill in them if they're borosilicate. They can be sterilized in the oven, in a pressure cooker, or autoclaved. You can scrub the crap out of them without creating huge gouges for bacteria to harbor in, unlike the Simply Orange jug mentioned.

Last but not least, the larger ones can be used for home defense.

The biggest advantage I see to the flask is the ability to boil, cool and ferment your starter in 1 vessel. I believe the reduced possibility of infection comes more from this fact than the shape. Flame and steam do a better job than star-san can. I made plenty of starters that were just fine without the flask, as I'm sure you do, but the one vessel part really is convenient!!

Also, if you end up with a stir plate you need a flat bottom that jars/growlers usually don't have.

It may or may not explode and the measurement are suspect. Even the best can be off 5%. The best way to check your Erlenmeyer is to put it on a accurate scale and see how close it is.

Home defense? Ah yes, the Erlenmeyer makes an excellent Molotov cocktail. In between revolutionary uprisings the Erlenmeyer could make a handy wine decanter.

Sterilization by means of boiling or baking seems like sound reasoning. I am not sure I could get away with borrowing the pyrex measuring jug for days at a time.
