Hops are categorized by % Alpha, the higher the more bitter. The highest I've seen was an 11%.
Champagne yeast has the highest tolerance for alcohol, since alcohol kills yeast, and more malt extract equals higher alcohol. Yeast eats sugars, uses oxygen to digest the sugar, it then exhales carbon dioxide, and poops alcohol so it's living in its own waste perse'.
The darkest I've seen is whats called 'Belgian Special B'.
Hope this helps.
