Slice up watermelon, discarding rind. Chop watermelon flesh into 1″ cubes, placing into a large pot. Once all watermelon flesh and juice is collected in the pot, heat over medium, stirring and mashing frequently, until watermelon flesh has broken down into liquid. Remove from heat.

Measure about 3.5 L / 14-15 cups / 120 oz of juice, reserve any remaining – you can drink it straight, or make cocktails from it! In large pot, combine measured watermelon juice (straining the seeds out as you measure!) with the sugar. Heat to almost boiling, stirring until sugar is dissolved. Remove from heat, cover with sanitized pot lid.

Once mixture has cooled to room temperature, add acid blend and yeast nutrient.

Using sanitized equipment, take a gravity reading. It should be in around the 1.16 area. Keep track of the number! (This is an optional step, but will allow you to calculate your final ABV %)

Using sanitized equipment, rack the clarified wine off the sediment, into a clean, freshly sanitized 1 gallon carboy. Cap with sanitized airlock, leave it alone for another 2-3 months. r

Repeat racking process. Leave wine alone for a month or two. By 6 months in, your wine should be very clear, and VERY tasty!

When your wine has been racked a few times and shows NO more fermenting activity for a month or so (no bubbles in the airlock, no more sediment being produced, you can move on to bottling:

Enjoy.. and start planning for next year’s batch(es)!
