2000 ML Flask

SKU: 7107



A larger size for larger batches of beer, or higher gravity beers. Sometimes you just need a big yeast starter for a big beer. The correct sized stopper is available in the related products section on the left. Currently this flask uses a 9.5 stopper. Do not apply direct heat to the flask.

Nice size
I like to make my starters in this flask, it works great.

Good size for yeast starters
Its actually a little larger than my old flask, so there is less chance of a boil over. It's not as thick so it can break more easily.

Good for making a starter
It has more interior volume than my other 2 liter flask. The glass is not as thick but so far it still works fine on the gas stove then after a minute on a oven mitt, it goes into the sink.

Good size for starters
1000 ML is too small, this is a good size. _x000D_I use it on a gas stove without problems, _x000D_I will say it's a little thinner than my friends flask, so it's not as sturdy or well made.

My second flask
Its a little thinner (i.e more breakable) than my other flask, but I got it so I'd have a back up. If you really want to brew well, you need to make a starter. IF you want to make a starter you need a flask and a stir plate._x000D_

It will work for making 2 liter starters but isn't as good as my old flask which was thicker. This flask is more likely to break and I worry when I heat it on the stove flame that it will crack. When I take it off teh flame, I put it on a mat for a few minutes so it cools a little, then put it in room temperature water, to minimize thermal shock. I checked the measuring lines and they are slightly off too.

Not the best
I have a lab grade flask that I compared this one too._x000D__x000D_1 - this flask is not as thick as the lab grade flask. I hope it can withstand the thermal shock of boiling my starter in it (gas heat), then moving it to cold water. In any case it seems more fragile._x000D__x000D_2 - the volume markings are incorrect. They read more volume than is actually in the flask. I know this by measuring with my other flask and with a measuring cup. The 1000 ML marking is 1/8 of an inch too low. The 2000ML marking is 1/4 inch too low._x000D__x000D_3 - on the plus side, it has a little more head space, so boil overs will be less likely to occur._x000D__x000D_4 - the bottom is not flat, its curved like a very shallow dome, so the stir bar may get thrown at higher speeds._x000D__x000D_I can not recommend this flask for making yeast starters. I would pay an extra $4 and get a better one.

Good for making a starter
I boil my starter in this flask using gas, take it out and set it on a mat for a few minutes, then put it in a sink with tap water. It can withstand the thermal shock. I am careful not to bank it and set it down on mats just in case. So far so good.

this size is just right.
I like this flask. It is perfect for my stir plate and any starter size for 5 gallon batches. I do not like using this for the boiling of starter wart. I sanitize it separately. I like using a sauce pan with a pour spout. The sauce pan is a lot safer because it is open. The smail neck on this thing causes boil overs for almost any time you touch it or put something in it. I have never had sanitation problems by just soaking it in StarSan solution while I boil in the sauce pan. I have burn marks on my hands from the three times I tried boiling in the flask. Never again! Still a great item. Don't forget an oxygen system and some yeast nutrient.

Needed to make a yeast starter with a stir plate
I put mine directly on the oven flame and when its done give it a minute to cool, then put it in cold water. When its cool, I put it on a stir plate. Never had a problem.

Can you heat wort in it on the electric stove?
Gordon P on Dec 28, 2016
BEST ANSWER: We do not recommend using them with an electric stove. Always a good idea to use it in a pot of water to heat it.
A shopper on Dec 25, 2016
BEST ANSWER: I don't recommend foam stoppers. When you use the flask to grow yeast, foam stoppers tend to prevent the introduction of air which is very important. Instead use a sterilized aluminum foil square.
