2010年10月28日 · Methanol has a lower boiling point that ethanol so think about the concentration of the "heads" it is basically all the methanol that would have been diluted in the fermented wort. But before boiling it is so diluted in the large volume of the water and other alcohols its probably harmless (I hope).

2009年7月22日 · Methanol boils at 64.7 centigrade (148.4 Fahrenheit), while ethanol boils at 78.4 centigrade (173 Fahrenheit), hence the reason why you would discard the first little bit as it obviously boils first (I'm sure everybody knows this already).

2020年2月21日 · Methanol and Ethanol form an azeotropic mixture, meaning they don't want to evaporate at their individual boiling points, they act as a single liquid. You need water/steam and time refluxing to break them apart (actually, the water will replace the methanol as the azeotrope with the ethanol).

2013年10月15日 · also little unknown fact about methanol poisoning is that the cure is ethanol :rockin: so logically speaking you cant go blind form drinking period. most of these misconceptions come from the days of prohibition and people producing spirits with chemical additions such as formaldehyde and from people creating poison in their bathtubs.

2022年10月6日 · Methanol boils at a temperature significantly lower than ethanol, so most of the methanol comes off first in a distillation run. This is why the first few fl oz (the "foreshots") of distillate are discarded when distilling.

2013年1月9日 · Dangerous methanol levels aren't really an issue in beer - all the "go blind" stuff and high methanol levels are an issue when you start distilling because as the mash heats up to 65C / 149F you start boiling off methanol and it starts coming out the end of the still -you could have a small glass of liquid if you gather it at this point in time ...

2021年11月29日 · Hangovers are caused by a whole range of things. Some guy on a video saying it's from methanol doesn't mean it's so. It's actually not mostly methanol, that's a regularly quoted distilling myth. Hard cider contains less than 0.1% methanol, which is less than 20mL in a 5 gallon batch, or about a tablespoon.

2009年1月22日 · The methanol doesn't do much in hangovers, since its in very minute amounts and a treatment for methanol poisoning is to take ethanol, so when you drink alcoholic beverages that contain some methanol you're counteracting the …

2015年4月26日 · In fact, one of the treatments for methanol poisoning is to drink a continuously steady amount of ethanol while you pass the methanol. This is a documented treatment. The web has articles about puppies saved from antifreeze poisoning by putting them on a vodka drip( true story) and of beer being prescribed as treatment in Africa.

2019年12月20日 · Naturally occurring methanol comes from the breakdown of pectin by means of enzymes (pectinase) that are already present in fruit and that break down pectin as part of the natural ripening process. Yeast cannot metabolize pectin so no methanol can be produced by yeast. Malt has exactly 0.0000% pectin so methanol is not a concern.
