Watermelon Concentrate
As a kid, remember eating frozen popsicles on a stick? When the frozen popsicle began melting, the sugary goodness came out first leaving a semi-tasteless block of nearly clear ice behind. Reason is flavor compounds dont freeze as completely as the water molecule, so the flavor compounds freeze last or melt first.
Juice a watermelon to get one half gallon of fresh juice. I take chunks of melon and mash them into a mesh kitchen strainer, then collect strained juice in a half gallon sanitized milk jug. Freeze solid. With lid off the milk jug, turn it upside down over the open mouth of a one-quart mason jar. Let melt and the concentrate will begin dripping and collecting in the jar. Continue to allow to melt until the mason jar is full which is one quart of level one concentrate. Discard (or drink) the remaining semi-clear ice block in the milk jug. Take the collected quart of level one concentrate and freeze in another milk jug. Once again, take this frozen concentrate and allow to melt on top of a mason jar until 16 ounces of level two concentrate is collected. You will now have reduced 64 ounces of fresh watermelon juice down to 16 ounces of concentrate.
Full volume watermelon juice is tasty but weakens your beer unnecessarily with unwanted water volume. I add this 16 ounce concentrate to a 5G kegged beer after fermentation while carbing. Enjoy this fresh and vibrant addition to your favorite beer as a subtle and remarkable taste.
