How would i go about making a hard sparkling ice tea? The ice tea is already in the 2L, bottled and sweetened from the store, do i need to add apple juice to this drink as well? or will a yeast starter from an old cider batch already have enough nutrients in it? or should i add a couple of raisins?
If i do add some raisins in the batch, will the raisin flavour come out into the drink or will it only help to feed the yeast?
Thank you!!
