Oolong is a partially oxidized tea known for its unique shape and bold aroma. Moderately caffeinated and with an intensity somewhere between black and green tea, oolongs are a great option for those looking for an invigorating and delicious beverage. Loose leaf oolong teas go through some of the most complex processing of any tea type. These processing methods were developed over many centuries, mainly as a means of preservation, hence why they tend to be tightly rolled up (this maintains freshness). Oolong teas contain some of the most complex, nuanced flavor profiles of any tea variety: generally floral, toasty, and/or slightly sweet. Heavenly Tea Leaves line of loose leaf oolong teas features traditional oolongs, single-origin oolongs, and artisanal varieties, among others.
