The CAO Special Edition line serves as a home for the brand's single-vitola special releases and experimental blends that fall outside the regular production portfolio. Each release features a unique construction, often incorporating rare or unusual tobacco components — from Cyprian Latakia pipe tobacco (Stokk) to rope-fermented Brazilian Fuma em Corda (Orellana) to a bourbon barrel-aged binder (Mortal Coil). Additional limited editions will be added to this line as they are released.
