Coffee Bean Extract
Here's another popular extract that is easy to make. We don't use coffee extract as often as other extracts, so I'll make one small bottle every 6 months so it's always available. Making your own coffee extract is cheaper than buying it in a store and more impressive. Great way to add coffee flavoring to a homebrewed stout. Will last forever if stored properly.
All these extracts, we really should invest in smaller brown bottles.
Beans
Crush up your beans. Crush, not grind. You want rough smashed pieces, not a fine grind. Use about 4 tablespoons for 1 cup of alcohol.
Alcohol
You can use vodka, clear rum, bourbon, or brandy for your extracts. Nip bottles work great as they're small and super cheap. 1 tablespoon of crushed beans per 1 alcohol nip should be enough to get a small extract going.
Bottle
Pour the coffee beans into your jar and then fill with alcohol. Put the cap on and give it a shake.
Age
Keep the extract out of direct sunlight and allow to age for 2-4 weeks. Don't forget to give the bottle a daily shake. After 2-4 weeks you can strain out the coffee beans and keep the extract in your cupboard for whatever needs you have.
