Hi, I made a keg of coopers corona for SWMBO and it turned out great, but since it will be drank out of glasses and pitchers instead of the fancy bottle with a lime wedge, I thought I would just add the lime juice to the keg and forego the hassle of having to cut lime slices or wedges. How much lime juice should I add? I could just add some a few times to adjust to taste, but would rather just open the keg once to keep from wasting CO2 too much. I was thinking a tablespoon for the 5 gallon keg.
