Honestly, make your own. Keep it simple, though - some base malt, wheat, light on the salt. 15g for 5 gallons, anything more kills the palate. Like margaritas? Add juice and zest from 4 limes at flameout. The lime and the salt... plus the sour... it's soooo good. Add some tequila if you want. Steep the lime zest in it before you keg.
