Rasa's 2020 batch is a bit different from the 2019 version. There are batch variations because Rachel tinctures ingredients herself. She's taken wine-making skills and brought them in, to put fruit into perfumery. She uses the concept of terroir (using materials available in a specific region) to build her perfumes.
You are not going to get the passion fruit note that I fell in love with in the 2019 version. You are, however, going to get a lot of other stuff (you'll get your money's worth, and then some. It costs the same, but it's worth more). There is some seriously good oud in here.
This perfume is alive. There is just something in there that your body wants more of. Yes, it is expensive, but she is doing something with natural perfume that no one else is doing. Most of the natural perfumers are using isolates to get those natural smells. Isolates leave the bright smell of the natural ingredient, help it last longer, but there is no benefit from the natural ingredient with this method (there is no negative effect, either, but it's worth pointing out). Here, you are getting some of the best natural perfume in the world.
Rasa 2020 would be great as an attar. I see Rasa 2020 as a winter edition of Rasa 2019. You get a smoky, resinous, beautiful dark oud. There are five ouds in here (from just one in Rasa 2019). She added oud from Ensar Oud in addition to the Rising Phoenix oud. There are no barnyard or fecal oud notes here. The pink lotus is not as aromatic as the 2019 version, but adds a touch of sweetness along with the osmanthus. It's a complete oud session.
In the 2021 version, she will be bringing back the passionfruit at the top. She has samples available of her perfumes on her site; it's worth checking out.
