Feels like roughly equal portions of 4 and 2 with a very healthy dose of 6 in position #3. It's a balanced kava with a distinctly Fijian feel. Your ears will ring before you fall over, though you can do that do if you want, and if you mix it thin you can grog all night.
Comparing it to other Fijians, KT Savusavu is headier than Squanch. Kava Vinaka is way heavier than Squanch. Squanch waka has a great strength/taste ratio, too. That is to say, it packs a very respectable punch without tasting too crazy.
I am full of Squanch right now though, so I might be biased. But I'm drinking Squanch right now because I like it. Sample size of one and all... Still, I'd recommend anyone to at least sample it.
