The large batch was perfect, not too sweet or strong. We used fresh squeezed orange juice, 1/3 cup to 1 Tbsp of sugar making 14 bottles.
The medium batch was also perfect. We added 1/2 Tbsn sugar and made 9 bottles.
It’s been 8 days and the orange 2nd fermentation batch is still not fizzy and tastes very sweet. Will wait another day or two.
