Has anyone had any negative experiences with Northern Brewers 2000 ml flask. I was surprised to see the reviews being so poor. |

The glass isn't overly thick, so you have to be a little careful. I wouldn't plunge it into ice water directly from the flame, but that's not good practice with any laboratory glassware.
I have both a 2000 ml and 5000 ml flask from NB, and I haven't had any problems with them. |

I'm usually very careful with my brew equipment. Having read your posts, I don't expect any problems. |

+1 to Dave and Bill. I have a 5000 mL flask from NB for the past few years as well, and haven't had any problems at all. Just used it to grow up yeast for an imperial porter.

Yeast (1728) went a bit nuts. I keep forgetting to get antifoam.

Do you guys like to use a foam stopper or rubber one with an air lock on the flask? |

I concur with the aluminum foil folded over the top of the flask. I pump 0.45 micron filtered air from an aquarium pump into the flask so there is always a net outflow from the flask. |

I don't do anything to sanitize it, but it's sanitary right off the roll. |

You don't need to sanitize the foil, but if you are really paranoid about it, you can tear off a square and just crimp it loosely over the mouth of the flask as it is nearing a boil. The steam will kill anything on it. |

Assuming you boil in a flask, good idea. I don't do that. Plastic wrap and paper towels are likewise sanitary right off the roll. |

+1 with Denny. I usually just use foil and make a "hood" with it so air can get it. My understanding of air is that the "nasties" continue flowing down and can't go "up" to get into the starter. I have a few NB flasks and never had any problems. |

I'm afraid of boiling directly in the flasks after having a 5 liter flask with 4 liters of wort in it explode on the stove! What a mess! The bottom cracked right off. Now I boil in a pan and place the empty flask inside an empty pan just in case it decides to break when I pour the boiling wort into it. I boil the wort in the pan for 10 minutes and pour it into the flask, slowly, cap with foil and let it sit for another 10 minutes to sanitize the flask and foil. Then simply chill it in the other pan it's resting in. |

Do you have an electric stove, mikel? If so, you need a wire trivet to separate the flask from the coils. Even with gas, it's not a bad idea to use a trivet. |

I stopped boiling in the flask when I cracked a 4L Pyrex brand Ehrlenmyer on a glass top stove. I had a little boil over and the interaction of the wort, stove top, and flask somehow cracked the flask.
I sanitize my flasks now with Starsan or Iodophor and I boil my starter wort in a big Pyrex measuring cup in the microwave. After boiling for a minute or two, I take the measuring cup and cap it with saran wrap and put it in a pot of ice to cool. The cooled wort is then added to the sanitized flask.
Much safer for my investments in flasks this way! |

It was on a gas stove. Maybe a trivet would have helped. Either way, too much mess to try it again! |

The one thing that can get up under foil is fruit flies. Not a problem most of the year. Came down one fall morning to start brewing and found several swimming in my starter with a foil cap. Stoppers and airlocks that time of year now. |
