I bought an old house that is finished in an arts and crafts style. All
of the woodwork has a interesting stain on it that the previous owner
described to me as "applejack". Apparently it was a popular color back
in the day, but I sure can't find it now. She had told me that you can
make it by mixing some other modern stains together. Does anyone know
how to create this color?

It is a dark stain that I would describe as very dark purplish brown.
The thing we started to love about it is that in areas of wear (around
doorknobs and stair railings for example), the purple nature of the
stain really shows up and gives the house some nice character.
