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.
Step 1: 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.
Step 2: 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.
Step 3: Bottle
Pour the coffee beans into your jar and then fill with alcohol. Put the cap on and give it a shake.
Step 4: 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.
