Borneo Zazen is - Borneo Zen on steroids! Every single note of the scent seems amped up a notch or two. The oil itself is of a coppery-golden colour and is quite fluid. The initial blast is all Jasmine, and this Jasmine is greatly enhanced by musk. Very soon the "jasmarine" accord of Borneo Zazen unfolds too. I think I did smell musk as one of the notes, however this was only a fleeting impression. The strong Jasmine accord slowly gives in at around twenty minutes, and Borneo Zazen gradually morphs into a delightful sandalwood-musk-oud combo, gently supported by florals. It is very incense-y in this stage, with a very slight earthy note from the Green Papua, and I suppose, from Vetiver. Side-by-side comparison of Borneo Zazen and Borneo Zen: Compared to an earlier version of Borneo Zen, Borneo Zazen contains a different, more ethereal, Jasmine. Either that, or the musk is at work here. The "older" Borneo Zen in its early stage seems more fruity - it has that peach scent of Jasmine. The peach note never entirely vanishes, and to my nose Borneo Zen is somewhat sweeter… it has the sweetness of fruits, of orange and rose. What I especially like is the duo of sandalwood and rose which starts after about two and a half hours; and which to my nose was one of the most delightful combos I have ever smelled. Borneo Zazen does not display that note, at least I didn´t notice it in the sample that Adam so kindly included with my order. Instead, Borneo Zazen is more woody, and I seem to get more of the musk-sandalwood-oud combo. Generally speaking, the two are very much alike, however the Borneo Zazen has a more potent, in-your-face scent. Borneo Zen is more calming and , at least to my nose, sweeter. While Borneo Zazen walks on the scene with a confident stride.. ..in addition, Borneo Zazen is more incense-y, but less floral in the mid and drydown stages. It is really a new take on Borneo Zen, one in which the musk and sandalwood shine through.
