First off the issue has nothing to do with the aging or fermentation of the tobacco. The cigars are made at My Father Cigar Factory in Esteli, Nicaragua and undergo the proper aging and fermentation. Also if the tobacco was young, you sat on it for another 14 months which it was not. Lastly, when you burn the cigar you would notice bad fermentation on how thick the carbon line is on the burn. A wrapper that doesn't burn well, or with a very thick carbon line is usually, but not always from fermentation issues. Another is over-humidification.
There are a lot of factors to the cigar tasting green, and the most common is something as simple as what you ate prior to smoking. I've personally smoked a lot of cigars by different people that tasted off because of what I ate. I would invite you to try another one and see if they still taste off for you. One of my favorite cigars to age, even before I came to Miami Cigar & Company was the Nestor Miranda Lancero. Other issues could be the storing of cigars, but I don't think that is an issue as I am sure you care for your cigars in a humidor at a proper humidity and temperature.
If the cigar still taste off to you, let me know.
