Ok, here's a sciency query for y'all. I get to my motel with plenty of beer. I've got Sierra Nevada Pale Ale, Sierra Nevada Wheat and O'Dell's 5 Barrel Pale Ale. The mini fridge isn't quite chilly enough so I ratchet the thermostat down a bit then load in the bottles, filling up each available space in turn but rotating the different flavors so that I have ready access to whatever suits my momentary fancy. The next evening when I return "home" from skiing I select a wheat beer and it's quite frosty. Next up is a SNPA, of course it's mighty chilly as well. When I get to the O'Dell's it instantly freezes as soon as I open it. This remains the case for each O'Dell's no matter what part of the fridge it came from, but is never the case for the other two brews no matter what part of the fridge they were chilling in. Can anyone explain this? As others have said, more carbonation - more pressure in the bottle - more expansion when the bottle is opened - more cooling effect due to expansion of the gas - beer slushy. mmmm....beer slushy....mmmmm. The giveaway hint here is that the beer was still liquid until you opened it. Why does it freeze when you open it? The expanding gasses take away heat. More expansion == more heat loss. //Walt |

Can anyone explain this? Chris Could be lower alcohol content in O'Dell's. Could be higher CO2 pressure in O'Dell's. Could be both. The alcohol content makes sense to me. But, while I can see how the higher CO2 pressure would keep the O'Dell's from freezing while sealed, I'm not clear on how it would prompt freezing when the pressure is released. (Not playing "gotcha", just geniunely curious) I have't had the O'Dell's, but IMHO the Sierra Nevada doesn't need to be anywhere near freezing to be palatable. CO2 contributed to two factors beer freezing upon opening a bottle of beer. First since Beer is mostly water, and water melts under pressure. (think how skiing and ice skating works) the pressure from the CO2 retards freezing prior to opening. once the bottle is open this "anti-freezing" function stops being present. Secondly when gasses expand they cool. This is the bases of all refrigeration units; mechanically compress a gas, cool it to room temperature, then let it expand thus extracting heat then repeat. The CO2 expanding and bubbling out of the beer will cool the beer slightly. Sounds like an invention for the next beer revolution, self cooling cans. Anyone want to invest? I think it is time to start rec.skiing.alpine.science -- Stephen B. NYC - Carpe Skium To reply remove the first spam only To separate the alcohol and CO2 effects, open one can of SN and one can of O 'Dell's (you can pour out and drink one half of each can) and put the half empty cans back into the refrigerator. At this point the two beers in the open cans should have about the same amount of CO2. If both freeze or neither freezes, you just wasted some beer, but one has to make sacrifices for science! C'mon Ernie, would you rather live in a world without science or a world without beer. I mean science is ok, but sacrifice beer? I think not. Chris If the O'Dell's freezes and SN does not, then the higher alcohol (plus sugars, salts, soluble proteins, etc) is keeping the SN from freezing. If O'Dell's does not freeze then the freezing during opening was caused by the expansion cooling of CO2. Ernie |

So how come the same thing happens to bottles of water at the local theater? Flat water, not carbonated. They take it out of their little fridge still liquid, but by the time you get to your seat it has frozen. Bruno. |

It is likely that the bottle was in the fridge for a relatively short time, and the water is super cooled, that is, the temperature of the water is below the freezing point but has not frozen yet. When the bottle is shaken the crystals get nucleated and the water freezes. Ernie |

Can anyone explain this? Chris Beyond the coldest beer in town Sept. 21, 2000 The proper temperature is essential for beer enjoyment. A beer served too cold will withhold most of its flavor. But while serving beer at room temperature brings out the flavors and aromas and is appropriate when judging beer, most drinkers prefer something cooler. Some general guidelines: - Serve fruit beers at 40-50° F. - Serve wheat beers and pale lagers at 45-50° F. - Serve pale ales and amber or dark lagers at 50-55° F. - Serve strong ales, such as barley wines and Belgian ales, at 50-55° F. - Serve dark ales, including porters and stouts, at 55-60° F. In "Ultimate Beer," Michael Jackson suggests a serving temperatures for each of the 450 beers covered in the book. Here are a few of those suggestions: My 2 cents. |

He and his wife took us out for a night on the town (Bruges). He ordered drinks for all of us; some sort of dark ale for he and I, and raspberry something or other "for the women". Her reaction was, "*FRUIT* beer? WTF?" ...or something equivalent. Chris |
