This recipe was copied from mlafnetzigger from home brew forums, thanks for posting.

Tweaked it slightly to account for a hop-sensitive Lactobacillus yeast and added a lacto preboil and cool.

Strike water ended up cooling down too much during transfer from BK to MT. Accidentally 2-step mash 20 minutes at 130 degrees, 40 minutes at 150. vorlaufed into boil kettle and transferred to HLT at 160.

Boiled for 15 minutes, chilled sweet wort down to 80, transferred 6.2 gallons to HLT as initial fermentation vessel.

ph measured at 4.5. I added too much lactic acid (added 2 oz instead of 1) which brought ph down to 3.5. let Ferment for 48 hours and tasted throughout.

Tasted sweet and tart, attractive peach color.

Boiled 60, used 0.5 oz of sterling hops in last 10 minutes to reduce IBU to less than 10. Added whole oz of coriander (didn't crush) as well as whirlfloc and 1.1 oz of Maldons salt.

Normal ferment in the mid to upper 60F's for 10-12 days.

I'm cheating and using a apricot tincture but here's his method for creating your own watermelon magic:

The "magic" is the watermelon addition. I froze 1/2G fresh melon juice in a milk jug. Turn jug upside down over a quart mason jar and let it melt. The concentrate drains first. collect 32 oz. Freeze that 32 oz and do the melt/drip trick again and collect 16 oz essence. This is your pitch when you rack to keg for conditioning. Freeze until ready to use with one day left in fermentation.
