By utilizing aerobic fermentation, the producers at Daterra introduce a specific metabolic environment during the drying stage, which can significantly influence the final cup profile. For those interested in how such techniques alter the chemical composition of the bean, our processing methods explainer offers a deeper look into these controlled environments. When evaluating the resulting notes of blackcurrant and rooibos tea, drinkers may find it helpful to reference the flavor wheel to better categorize the nuanced acidity and herbal undertones present in this unique lot.
