I just received the Aleman Seco & Aleman Capa/Banda. These leaves are so awesome that it made me join the forum and share my thoughts.
These leaves have a great aromatic quality to them. Quite cedary/pine-like, incense-like, reminding me of a very mild Latakia without the floral-ness of Latakia. Aleman leaves are very well aged.
Though I don't think the Capa/Banda is of the wrapper quality because of the damages and holes the leaves have, the current pricing makes it a great deal. And indeed about 70-80% of the leaves are usable as binder/wrapper. For the taste alone, this is a great find.
For my use, Seco leaves make a great filler. It really adds an extra dimension to the cigar blends. It brings a slight earthy smoky cedar notes with a noticeable sweetness.
Here is a cigar blend recipe I tried using the aleman leaves. This is one of the better ones I rolled. I plan to roll about 5 or so and let them meld for a month or two.
Filler: 1.5 Dom Seco, 0.5 Aleman Seco
Binder/Wrapper: Aleman Seco & Aleman Capa/Banda
