For me the instant kava is a bit different than the real thing, it depends on how the instant kava was made, there are a lot of instant kava that is made from extract and that is the difference I do not like, there are some instant kava that is made from spray drying the aqueous extract, that kind is not really an extract it is just the kava made from fresh root and water then they take out all the fibers and spray dry the kava drink so in actuality you are only getting the potency of a regular kava drink and not really an extract. So for me I would drink a instant kava made from the aqueous extract but not the solvent or CO2 based extracts. I have not found a flavored instant kava that I like, if you have a problem with the taste then use root beer and take a sip after drinking the kava and it will cut the flavor of the kava. Aloha.
