So I began this adventure searching far and wide for a recipe and to my misfortune i was unable to find one that was able to give me workable numbers.
So I started out on my own. what i used that barely yielded 10 bottles, i will use more next time.
59 fl oz. of grapefruit juice (I used Florida natural, too lazy to juice that 7-8 grapefruit)
48fl oz. of white grape juice (i used welchs white grape fruit concentrate and mixed the water in)
and for every 12 ounces of liquid i used 1 oz of sugar.
i really liked the aspect of drinking esp. soda right out of the bottle. im sure you could do this the old fashioned way with a pinch of yeast but i didnt want to deal with another factor for the first round. flavor was enough for me.
I force carbed at 30 psi set and forget method after a week or so, brought the psi down to 12 and counter pressure filled it into the Corona bottles that i soaked in star san for 3 days to take the label off of them.
i understand that counter pressure filling is a pain and not everyone has one, i just didnt want to go through the hassle of getting the right amount of hosing to gas ratio. my beer is on tap i dont need my soda too but that was it
it turned out perfect. In my completely unbiased opinion
it was better than an Izze. I didnt strain it and there was pulp in the bottle. At first this annoyed me but i do think it made it look and feel more homemade but if you absolutely hate pulp just strain it out
this taste like your drinking a grapefruit a little sweet but still tart on the back end if you like grapefruit you will like this. i am open to any feed back i am in the process of making a small batch of Key lime soda right now so i will let you know how it goes. cheers
