Three, it's the magic number. OTP - a special series of sours, each batch combining a trio of unusual ingredients based on the perfect principle of three elements. This batch we've aged a cherry infused sour in bourbon barrels before spiking it with a shot of Crocky's Cold Brew coffee, creating a unique threefold flavour combination of sour cherry, bourbon, and coffee. Omne Trium Perfectum, no more no less - for some reason, things just work better in threes.
