Its basically up to you how concentrated you want it. However, the can says the serving size is 2 oz., or 8 oz. prepared. Since the prepared amount is 4 times larger than the concentrated amount, add 4 cans worth of liquid (water, lime juice, or alcohol) to dilute the mix. I use 2 cans of water, and then 1/2 can of triple sec, 1/2-1 can of tequila, and some fresh lime juice to freshen up the mix.
