I’ve only tried this hot so far, sweetened and unsweetened. Adding rock sugar just makes it taste fake, so don’t do it the first time you are trying this! I much prefer it without sugar. It lets the floral oolong smells and flavors come out much more and stand up well with the pineapple. The liquor is a gorgeous, sunny, perfectly clear gold. The leaves are pretty too! They unfurl and look so perfectly whole. Upon second steeping, the pineapple flavor will be pretty much completely gone, but that lets you taste the good quality (I think) oolong they used for this blend!
