Just trying my first roast of the Wahana, its 6 days old so a little fresh, i roasted mine to just the start of C2, i am finding it surprisingly rounded and smooth. No single flavour dominating at this stage. In some ways more like a good brazilian than a typically Indo bean. Adjusted the grinder finer before pulling a shot based on the previous posts and it proved to be the right move, I rarely have to adjust the K10 but this bean requires a step change. Will be interested to see how it develops over the next week.
