I made this one as a cold brew. I find that I do not like hibiscus in cold brews so I only brewed this one for 4 hours, instead of my usual 12+. I found that even though I did less time, the hibiscus was just starting to get strong. There is a very light citrous, orange, grapefruit flavour. No peppery grapefruit taste. It would have been nice to brew for longer and have more grapefruit flavour but then the hibiscus would have been too strong. I like this one better brewed hot.
