Humidity and Cigars 135 Rule

The 135 Rule: Why It Matters for Your Premium Cigars

At San Giuseppe, we put a lot of heart into every cigar we craft. The last thing we want is for your investment to go to waste sitting in a bad humidor. That is where the 135 rule comes in, and every cigar lover should know it.

The rule is simple. Take your storage temperature in Fahrenheit and add your humidity percentage. That number should never go above 135. So if your humidor is sitting at 70 degrees, you want your humidity at 65% or below. Simple as that.

The reason this matters is tobacco beetles. They are naturally present in tobacco leaves and they wake up fast when things get too warm and too humid at the same time. Once they hatch, they will tunnel right through your cigars and there is no coming back from that.

The sweet spot we recommend is around 68 to 70 degrees and 65 to 68% humidity. A lot of people go with the classic 70/70 rule but that puts you right at the edge, especially in the summer months. Play it a little safer and your cigars will thank you.

Whether you are storing a box of our Robustos, aging a bundle of the Big Joe Gordo, or keeping a few John Daly Long Games on hand for the course, proper cigar storage is what keeps that draw and flavor exactly where it should be.

Smoke it right. Store it right. That is the San Giuseppe way.

What Happens When The Humidity for Cigars is not there

We have all been there. You open your humidor after a few weeks and something just does not look right. When your humidor runs too hot and too humid, the moisture inside the tobacco expands beyond what the wrapper can handle. You end up with cigars that are soft, spongy, and nearly impossible to draw from. They burn uneven, they taste bitter, and all that complexity the blender worked so hard to create just disappears into a bad smoke. On the flip side, too dry and the oils that carry the flavor dry up fast. The wrapper starts to crack, the filler loosens up, and the whole cigar falls apart before you even get through the first third. Neither extreme is acceptable when you are smoking something worth your time. The 135 rule keeps you right in the middle where the tobacco stays alive, the flavors develop the way they were intended, and every cigar you pull out of that humidor smokes exactly the way it should. At San Giuseppe, we built our brand on doing things the right way from the ground up. How you store your cigars deserves that same standard.

From Seed to Smoke: How a Premium Handmade Cigar Is Created

By San Giuseppe Cigars

Most people pick up a cigar, light it, and enjoy the moment without ever thinking about what went into making it. And that is completely fine. That is exactly what a great cigar is supposed to do, pull you out of the noise and into the moment. But here at San Giuseppe Cigars, we believe that when you understand the craft behind what you are smoking, the experience gets even better. So let us walk you through it, from the seed in the ground to the band on the cigar in your hand.

It All Starts With the Seed

A premium handmade cigar begins long before any rolling table or blending room. It starts with the seed. Tobacco seeds are incredibly small, roughly the size of a grain of sand, and choosing the right variety is one of the most important decisions a grower makes. Different seeds produce different flavor profiles, different burn characteristics, and different wrapper textures. The genetics of the seed determine much of what ends up in your smoke.

At San Giuseppe, our roots run deep in the Dominican Republic, where we built relationships with master growers and blenders who have been doing this for generations. The soil in the Cibao Valley, often called the Napa Valley of tobacco, produces some of the finest leaves in the world. Rich in nutrients, perfectly drained, and kissed by the right amount of sun and rain, that ground grows tobacco that cannot be replicated anywhere else on earth.

Growing and Harvesting

Once planted, tobacco takes roughly 60 to 90 days to reach harvest. During that time it requires constant attention. Farmers walk the rows daily, monitoring for disease, managing sun exposure, and removing the flower buds in a process called topping. Topping redirects the plant’s energy from reproduction into growing larger, more flavorful leaves.

Harvesting is done by hand, leaf by leaf, working from the bottom of the plant upward over several weeks. The position of a leaf on the plant matters greatly. Leaves near the bottom, called volado, burn easily but carry lighter flavor. Leaves in the middle, called seco, bring balance and body. The leaves at the top, called ligero, are the most potent. They sit closest to the sun, develop the most oils, and carry the deepest, richest flavor. They also burn the slowest, which is why master blenders use them sparingly and always place them in the center of the cigar.

Curing and Fermentation

After harvest, the leaves go into curing barns where they hang for 45 to 60 days. This process draws out the moisture and transforms the green leaf into the brown tobacco you recognize. There are different curing methods depending on the desired outcome, but air curing is the most common for premium cigars, allowing the natural sugars and chlorophyll to break down slowly.

After curing comes fermentation, and this is where the real magic happens. Leaves are stacked into large piles called pilones. The natural heat that builds up inside those piles triggers a chemical reaction that reduces harsh ammonia, mellows the tobacco, and develops the complex flavors that make a great cigar great. Master blenders monitor the temperature of these pilones constantly, rotating the leaves to ensure even fermentation. This process can take anywhere from a few months to several years depending on the leaf and the desired result. Aged and properly fermented tobacco is one of the biggest differences between a premium handmade cigar and a cheap smoke.

The Blend

Once the tobacco is cured, fermented, and rested, the blending begins. This is where art meets science. A master blender selects different leaves for three distinct roles inside the cigar. The filler goes in the center and creates the core of the blend. The binder wraps around the filler and holds the shape while also contributing to the burn and flavor. The wrapper is the outermost leaf, and despite being just one layer, it accounts for anywhere from 30 to 60 percent of the flavor you taste. A good wrapper leaf is smooth, oily, and nearly flawless.

At San Giuseppe, every blend we release goes through an extensive development process. We taste, we adjust, we taste again. Getting a blend right is not a shortcut kind of process. It takes time, patience, and an honest palate. That same attention to detail is what you taste every time you fire up one of our Robustos, Toros, or the Big Joe Gordo.

Rolling by Hand

Once the blend is finalized, the leaves go to the rolling room. A skilled cigar roller, called a torcedor, can produce anywhere from 100 to 200 cigars per day depending on the size and complexity of the cigar. They work with their hands and a simple wooden tool called a chaveta to bunch the filler, apply the binder, and stretch the wrapper leaf around the cigar in a tight, seamless spiral.

This is a skill that takes years to develop. The tension has to be just right. Too tight and the cigar will not draw. Too loose and it burns hot and fast. A perfectly rolled handmade premium cigar feels firm but has a slight give, draws effortlessly, and holds an even burn from start to finish.

Aging, Quality Control, and the Final Product

After rolling, cigars go into aging rooms where they rest for weeks or even months, allowing the different tobaccos in the blend to marry together. This is what separates a rushed product from a refined one. Once aged, every cigar goes through quality control, checked for construction, weight, draw, and appearance before it ever gets banded and boxed.

By the time a San Giuseppe cigar reaches your hands, it has traveled years of work, thousands of miles, and passed through the hands of some of the most skilled craftsmen in the industry. We carry that responsibility seriously because we know what it means to hold something that was built with that much care.

So the next time you sit down with one of our cigars, take a moment before you light it. Feel the wrapper. Smell the foot. Appreciate what went into it. Then light up, relax, and enjoy every draw. You have earned it.
