Habana 2000 is basically a cross between: Havana 2.1.1. > Vuelta Abajo. -The reason for starting Havana 2000 was to develop something that maintains the character of both El Corojo and Vuelta Abajo but resistant to blue mold and other tobacco diseases. The man I received Havana 2000 and Habana 2000 told me that there should be a third version (Habano 2000) that was also cross with a American tobacco. I asked if it was about Connecticut Shade (because that was what I have read) His Answer was "I have no information one that, but I do not think so. It would be my fault to get a new variant with similar flaws to get a better result". You need to know this:Havanna 2.1.1. Is a variant created in the early 1980's by crossing: El Corojo> Bell 61-10 (a mild cigarette tobacco that is more resistant to blue mold than cigar tobacco). I would like to clarify this because I have seen saviors who confused this with Havana # 211 which is a very nice Cigar Filler created by a crossing: Pages Comstock> Havana # 38 (At the end of the 1930s)
