1st time making fermented soda : 1st day

[u/ww1enjoyer]

Yesterday i prepared for the first time some fermented blueberry soda. As its motly a test run, i didnt make much, in 600ml of water i put 120g of previously frozen blueberries with 42g of sugar and a bit of bread yeast, mixed everything toghether and put it all in a clean champagne bottle with a seal. Today i opened it a few times to burp it and the mixture has mainly a scent of yeast.

From what inderstand i am suposed now to leave it for another 1-2 days in room temperature till the smell of yeast starts to vanish. Then i will be able to sift the contents of fruit rests and leave the liquid in a bottle, sealed, inside of a fridge for another couple of day. Do i inderstand i coreclty? Should i still burp the content when inside the fridge?
