Had a weird thought this morning after my damn cat woke me up at 5:50 a.m. and I stared at the ceiling for the next two hours. I was wondering if there's some underlying mathematical rule to what constitutes a good blend, and something popped into my head for blends that have worked for me. Mind, "blend" for me is the Cuban meaning, where it's percentages of one set of primings, because I use only one set of leaves for all my "blends," and the same binder and wrapper across all blends, so the degrees of flavor/aroma/strength/burn are always consistent, as they would be in a Cuban cigar factory. Here's what I came up with:
The 1 2 3 = 6 blending rule
Seco = 1, viso 2, ligero 3.
Total for a good blend should be 6-6.5 pts across 3-3.5 leaves for a medium-sized vitola.
Sample blends that I have rolled and I know are good:
Balanced: 1 seco(1), 1 viso(2), 1 ligero(3) = 6
More burn, rich flavor: 2 seco(2) + 1/2 viso(1) + 1 ligero(3) = 6
Strong and good: 1.5 seco(1.5) + 1.5 ligero(4.5) = 6
Med-Strong with an emphasis on viso aroma: .5 seco(.5) + 2 viso (4) + .5 ligero(1.5) = 6
Strong with emphasis on ligero flavor: 1 seco(1) + 1/4 viso(.5) + 1.5 ligero(4.5) = 6
Mild but with good viso aroma: 2 seco(2) + 2 viso(4) = 6
Classic mild Cuban robusto: 1 seco(1) + 2 viso(4) + "skinny 1/2, i.e. 1/3" ligero(1) = 6
When you start coming up with blends that don't equal six, they might be more prone to problems of overall balance. This idea was inspired when I was reading an interview with an old Cuban lady roller from Laguito where she talks about how to modify the blends: there was always a balance thing going on: "If I want to add some of this, I have to take away some of that." Whether it was a strong, mild, whatever blend, it was balanced.
