Syrian is definitely not as prevalent. Orientals are more noticeable early. Still a pleasant blend. I have a couple of tins remaining and plan on smoking soon. IMHO doesnt need any additional aging.
McClelland 3 Oaks Syrian (2010) in a Bekler Geometric. One of my favorite blends. Very sweet flavor I assume from the Syrian. Going to be smoking this all weekend! puffy
