HELP our fermented sodas bursted 3x, what are we doing wrong?
hello! for our school project, we decided to create fermented sodas. we settled on two flavors: apple-ginger fusion and a pear-tamarind one.
the first method we tried was boiling the ingredients with some cinnamon sticks, star anise, and cloves. we mashed it and strained after letting it cool completely before transferring to a swing top bottle with activated ginger bug. we did that last may 16 and just today it bursted. we're burping it everyday, so we're unsure why it happened.
the second method that we tried was the juicer method. we put the ingredients into a power juicer and adjusted the taste to our liking with honey. we put everything on a swing top bottle (again) with activated ginger bug. we did that just yesterday and the apple-ginger exploded earlier today while the pear-tamarind exploded just moments ago. i burped the pear-tamarind one, so i don't know why it bursted as well.
we lost three of our bottles and we don't know what to do 🥹 the only one we have left was the pear-tamarind one we did last may 16, which up until today doesn't have any carbonation or fizz. we have to bring it to school next week for tasting and we're afraid if we do it again, we'll not have enough time. also, we don't have that much money anymore since the materials and ingredients were expensive
can anyone help us in this case? is there something wrong with the ingredients we used or the method? is there something we could do to avoid this in the future? what method will you recommend? can we use other containers aside from swing top bottles to ferment our sodas (we're kinda scared of swing top bottles now)?
thank you to everyone who will have insight 🙏🏼
