We used about 13 passion fruit and strained out the seeds w a little water and made over a cup. Using the medium batch (a tad strong just a little) added additional cup of distilled water and 2 pumps sugar water. We made 7 bottles w 1/3 cup passion fruit juice and 2 tsp sugar.
The large batch was on strong side we used 1/2 Tbsp sugar and made 15 bottles.
We pulled passion fruit at 4 days and was just right – a little bit of eruption but not much.
