Methanol (methyl alcohol) is another popular fuel alcohol, frequently bought in the yellow HEET bottle because HEET is so widely available (at least in the US).  You do have to carry a bit more methanol to do the same amount of cooking since methanol contains fewer calories per gram* than ethanol.  Methanol fumes are toxic, and methanol absorbed through the skin is toxic.  How toxic?  If you're cooking out doors, I don't think fumes will be too bad if you're observant of wind direction and position yourself accordingly.   I don't have a way to state a safe limit for skin absorption, but handling with care should be enough.  It's not like you hear about a lot of through hikers on the Appalachian Trail (AT), where yellow HEET is easy to get and very popular, getting stricken with methanol poisoning.   Methanol has a higher vapor pressure than ethanol and works better than ethanol in cold weather.  I can't comment a lot on methanol performance in cold weather because I typically bring a gas or liquid petroleum fueled stove for cold weather.  Conversely, methanol can have "runaway thermal feedback" in hotter weather.  "Runaway thermal feedback" basically occurs when the alcohol gets so hot that it boils really violently and doesn't burn efficiently.  Adding water (see remarks above) can help calm down a burn so that the alcohol can burn more cleanly. http://adventuresinstoving.blogspot.com
