I finally got around to trying the frozen Nene I ordered back in January, I think. No funky smell (I was worried the kava had defrosted and was spoilt), and the refreshing smell and taste of cucumber hit me straight away. Lovely kava, very gentle relaxation and no sedation until night time when I slept really well. I ordered some more last week and once again everything had melted - the double packed ice pack and the kava was not even cold. I got the pack within two days of shipping but I was a hot day and even though I got to the mailbox straight away I obviously was too late to save it. I mixed up a batch but the smell was definitely off - funky, almost moldy smell, and no delicious cucumber notes. Sadly it went in the trash. Didn't want to take any chances with getting sick - got a hectic and stressful time ahead of me.
However, I did love the effects from the first batch I tried, so I may splurge and get the one day shipping AND wait until we have cooler temperatures.
