How frustrating. I just looked at my starter from a couple of days ago, and noticed my flask is cracked at the bottom, and I have a very slow leak out. VERY slow. The crack does extend along the length of the bottom. Do you guys think its safe to use the starter? I was planning on brewing a pumpkin ale today. I am only concerned about infection.

I would be more concerned about pieces of glass in the starter.

I wouldn't worry about it.

RDWHAHB, but definitely discard the flask after pitching the starter.

I'd use it, but I'd pick it up with the help of a spatula...

This is the second flask I've lost this way. I have an electric stove, where I'm doing my starters. I think somehow I'm cracking them while they are cooking on the stove. I'm gonna try a bunson burner next time. At 25 bucks a pop, I can't afford to buy one once a year!

Chad, you should make a simple trivet from a piece of coat hanger wire and place it between the electric burner element and the bottom of the flask. This should greatly minimize cracking of the glass and increase its life.

What Bill sez. You are definately cracking them by setting it directly on an electric eye. Just bend a piece of coathanger wire into a triangle that fits under the flask.

And don't take the flask directly from a burner of any sort to plunge it into a cooling bath. Even tho the flask is pyrex or kimex, you need to let it set on a potholder or the like for a minute or two before doing that...

Have you ever considered boiling your wort in a small pot and transferring to a 1 gallon, sanitized jug? They're free.

Quick way to make a big mess unless you let the wort cool in the pot for a while first. I got tired of boiling over in a flask so that's basically what I do with a flask. They CAN take boiling temps that quickly as long as the flask is at room temps and not cold.

I've got an erlenmyer flask, but I've almost stopped using it in favor of a quart canning jar. They're made to take the heat. I just boil them in the microwave to sanitize them, then pour in the wort from one of the pint jars I pressure can it in. I started using the jar when I was experimenting with open starter fermentation and stuck with it because it was lots easier than the erlenmeyer.

I boil in a pot, cool in a pot, then pour into a flask with a sanitized funnel.

I do the same as Denny, except I use a gallon growler.

Yeah, flask, jug, whatever...I use flasks for smaller amounts and a gal. glass jug for starting a tube in 1/2 gal. of wort.

Better yet, I boil in a pot, and while that's under way, I put a one gallon jug in the oven and set it to well, ideally 212F. When the starter is ready I transfer it to the hot jug, put on an airlock, and pop an iodophorized cotton ball in it. Any air that gets sucked in during cooling is sterile. Voila! A sterile starter!

Your starter should be just fine, but I'd replace the flask ASAP.

I'm fairly certain that was assumed.

Yes, I am cooling the wort before pouring it into the gallon jug. The flask does sound nice in that you only have one thing to sanitize/clean.

Ken,

Air sucked thru the iodophor-soaked cotton ball isn't likely sterilized.

I've used the cotton trick successfully with a mason jar, when I was making sterile rye grain medium for mushroom mycelium culture. Poked a small hole in the lid, epoxied a 1/4 inch diameter by 3/8 inch tall stub of tubing on it, stuffed it with cotton and pressure cooked it. My understanding is that the cotton fibers create what's know as a treacherous path (no kidding) for any incoming organism. Basically, they bump into a filament and get stuck.

Chad,
25 bucks is a lot for a flask. Check out Cynmar - here is a 2L for 13.80

http://www.cynmar.com/product_info.php?cPath=187_188_77&products_id=4660

I use these exclusively, boiling 2 oz DME in 1L water on a gas stove with a piece of aluminum foil on top and wrapped over the sides a few inches. when finished, I slip a rubber band over the foil, then put it into a sink of cold water to chill - about 10 minutes at most. some of my flasks are several years old - never had a crack yet (knock on wood).
