Whole coffee beans.  Light roast.  Dry bean post fermentation 24-30 hours.  I've liked Kenyan beans in a coffee Lager or coffee Blonde.

so the light roast coffee beans dont contribute much colour? i always wondered about that

My experience with using coffee beans is they do not add any color at all if they are used whole — not ground or crushed.

I make a delicious coffee crème brûlée that is Snow White, yet has a pronounced coffee flavor.  They are added to the egg/cream mixture (steeped) for 15 minutes while the mixture is hot on the stove.
