I bottled my cider about 4 days ago using about 1/4 cup dextrose to 4L for carbonation Prior to this it sat is secondary for 4 weeks with no bubbling happening.

I haven’t noticed any bubbling so is carbonation happening or have I done something wrong?

Thanks

Ignore the plastic bottle. Just wanted to try it out from the fermenter and chill it before.

When i shook it, it foamed up. Generally the foam isnt this much.

I added just apple juice, sugar and yeast. Its stored at 24 degree celcius to age. It has been aging for 4 months now.
