Is it possible to have a butter-scotch flavor in some brew?

Diacetyl:, Fermentation by-product that may lend buttery or butterscotch notes to beer. This is considered an off-flavor in excessive amounts in any beer.

Do you have it or are you wondering how to make it?

Wondering how to make it.

Recipes 

Pick a yeast that is kown for leaving diacetyl in the beer after fermentation is complete. There are some styles of english ales, that are known for their butterscotch notes in them.

The literature usually shows how to avoid diacetyl, but not how to produce it in a controlled manner. The problem with creating diacetyl by doing everything wrong might be the fact that you may also get other "off-flavors", which may not be desired.

Irish ale yeasts (like WLP004) will produce butterscotch, scottish strong ale yeasts even more so.
