@Ensar, so what type you personally prefer? gentle fumigation? or full on blast style?
Well, since you asked about my personal preference.... I just had an amicable debate with @Oud_Learner about this during our Sri Lankan session. He insisted that the burner with the coils inside (a.k.a. the 'Subitism' burner) is appropriate for heating Kyara, if you modify it to be temperature adjustable. And I was just saying, How can you put Kyara on a burner
like that? Hot red coils inside, proper smoke coming out of — Kyara slithers?? ('Tak boleh laah!')
To me, the burner should ideally be running for hours on end, while you forget it's there, and are suddenly reminded by unexpected whiffs of Kinam coming out of nowhere that there is a 'listening' session going on.... So ideally, the fumigation should be so gentle you hardly remember you're partaking in it, and only if you put your nose to the heater (can't really call it a 'burner') you get incessant whiffs of the gentlest Kyara vapors.
That's not to say that I don't use high heat. You can't really heat other types of wood like that, unless they're from the Kyara family. Try heating old Cambodi wood, or high grade Port Moresby.... you'll get whiffs of it, but will miss out on the most riveting facets those woods have to offer, which truly shine on somewhat higher heat.
And for a distiller, doing different styles is important. So I did the same exact thing you pulled off with the Si Lani and Old School Vietnam with oils like Aroha Kyaku and Oud Dhul Q. To me, the apex of that genre was Qi Nam Khmer though. The most incensey profile Cambodi ever, with just the right dose of 'fumes'. I really miss that oil....
