Cold Brew Coffee Trial 1.

Introduction:
Everyone loves coffee and one of the current coffee trends is "cold brew". This cool manifestation of coffee requires little equipment or technique to create. With a little experimentation, I hope perfect the recipe and procedure.


Ingredients and Materials:
1 cup whole coffee beans
4.5 cups of filtered water (eliminates tapwater taste variables)
Coffee grinder
Brewing vessel
Airtight storage vessel 

Procedure:

• Course grind coffee beans (should appear courser than sand)
• Add grounds and filtered water to brewing vessel (see figure 1.)
• Store brewing vessel at room temperature for more than 12 hours but less than 15 hours (variable for future experimentation)
• Pour cold brew from brewing vessel through a fine sieve into the airtight storage vessel (see figure 2.1 and 2.2)
• Seal cold brew in airtight storage vessel (see figure 3) and store until drinking (store in the refrigerator for increased temperature reduction)
• Drink and enjoy (I am enjoying my first glass of cold brew as I write this post)

Results and Observations:

The coffee has strong flavor (stronger than hot brewed coffee which has been forgotten and allowed to cool down) and lacks some of the acidic taste. These findings are consistent with reports about cold brew. Further testing is needed/desired
