一.產品介紹

在玉溪(xi)(xi)市(shi)八縣一區，這里的(de)煙(yan)葉在全省都(dou)是最優的(de)，但大(da)部(bu)分都(dou)被(bei)紅(hong)塔(ta)集(ji)團收(shou)購了，只有(you)很少的(de)外調(diao)到省外。現在，紅(hong)塔(ta)集(ji)團的(de)原(yuan)(yuan)料基地在省內主要有(you)玉溪(xi)(xi)、大(da)理、楚雄(xiong)、昭通，每年收(shou)購量(liang)在500萬擔(dan)左右，用于近500萬箱名(ming)優煙(yan)的(de)生(sheng)產。來自云煙(yan)之鄉(xiang)玉溪(xi)(xi)的(de)原(yuan)(yuan)料，是紅(hong)塔(ta)山幾十年不衰的(de)根本原(yuan)(yuan)因。“玉溪(xi)(xi)”煙(yan)就是全部(bu)選用玉溪(xi)(xi)煙(yan)葉來做的(de)，所以他們說，天下煙(yan)葉在云南，云煙(yan)之鄉(xiang)在玉溪(xi)(xi)。
