You may be able to find a (micro)brewery that makes Ale (there are literally thousands), wants to rebrand to "1" and pitch the idea to them that ale1.com is a good fit for their product, but not company.
Big beer companies have big money and could buy the ultimate generic if they wanted to, but they already have an established name/brand like Miller, Budweiser, etc. You can't convince them that just because they will get in type in traffic from that site they will increase their sales because people prefer their own beer, typically won't switch but will try it.
Other than that, they're dead domains as mentioned above.
