Cigar Making: Bunching Methods Explained

Bunching is the cigar’s internal architecture. It defines the airways you draw through, the way oils heat and vaporize, and how evenly a blend burns. The method—entubado, accordion, book, or machine‑assisted—determines how stable and repeatable that experience is.

Quick take Bunching shapes the micro‑chimneys inside a cigar. Entubado (each filler leaf rolled into a tube) yields strong columnar airflow and consistent draws; accordion balances speed and uniformity; book is efficient but requires finesse to avoid flat spots; Lieberman‑assisted builds favor repeatability at scale. Whatever the method, even channels + steady storage deliver the flavor.

What the bunch actually does (airflow, heat, and moisture)

Airflow. Filler geometry creates a network of paths. Too few or pinched paths → hard draw and coning; too many wide paths → hot, fast burn with washed‑out aroma. The aim is a gentle, continuous resistance across the length of the cigar.

Heat distribution. Even path density spreads combustion heat; clumps or flats concentrate it, causing tunneling or canoeing. A good bunch keeps the coal round and centered.

Moisture dynamics. Leaves absorb and release moisture at different rates. Uniform folding/tubing helps the cigar equilibrate quickly after rolling and after every opening of the humidor.

MethodAirflow geometryStrengthsRisks if rushedBest use
Entubado Parallel micro‑tubes, ligero centered Very consistent draw; protects against plugs; excellent for aging Collapsed tubes if rolled too tight; time‑intensive Premium long‑filler, heavier ligero blends, figurados
Accordion (fan) Z‑fold “springs” across the binder Good uniformity; faster than entubado; forgiving Edge choking if folds stack; uneven at the foot if misaligned Broad daily production; robusto–toro ring gauges
Book (booking) Leaves stacked and folded like a book Efficient; repeatable in experienced hands Flat planes → hot lanes; draw inconsistency if binder tension varies Value lines, mixed‑filler or lighter blends
Lieberman‑assisted Filler arranged, binder applied with machine apron Throughput and repeatability; consistent binder tension Over‑compression if settings are off; less craft “tuning” per stick High‑volume SKUs; some long‑filler lines use it well

Entubado (entubar): method and checkpoints

  1. Arrange the blend. Ligero toward the core for axial strength, viso/seco to complete the cylinder.
  2. Tube each filler leaf. Roll into loose, even straws; align ends at the foot for a clean light.
  3. Bind with uniform tension. Binder should compress the tubes just enough to stay coherent without collapse.
  4. Balance the head. Avoid a dense knot under the cap; keep path density continuous into the head.

Why it works: Discrete tubes resist lateral collapse and preserve parallel channels. The cigar draws the same today and six months from now—with proper storage.

Accordion (abanico): method and checkpoints

  1. Fan the leaves. Fold each leaf into a gentle Z, rib aligned for spring.
  2. Stagger the folds. Avoid stacking the same fold edge in one line.
  3. Binder, then roll. Wrap with consistent pressure; feel for any “flat bar” along the length.

Why it works: The Z‑fold creates repeating channels across the cross‑section. It’s faster than entubado but still highly uniform when disciplined.

Book (booking): method and checkpoints

  1. Stack by role. Place ligero where support is needed; sandwich with viso and seco.
  2. Fold like a book. Keep layers thin; avoid thick “spines.”
  3. Binder discipline. Slightly higher care on tension to avoid choking flat planes.

Why it works (and fails): The simplicity is the virtue—and the risk. Done well, it’s clean and efficient. Rushed, it creates hot lanes and draw variability.

Lieberman‑assisted: when to use, what to watch

  • Consistency at scale. The apron sets binder tension; operators stage filler for even density.
  • Watch compression. Settings that are too tight produce hard draws; too loose, airy burns.
  • Long‑filler use. Many factories run long‑filler on Lieberman with strong QC; it isn’t limited to short‑filler.

Method × blend × ring gauge (selection guide)

  • Heavy‑ligero, large ring (52–56): Favor entubado or entubado‑core hybrid; keeps the core breathing.
  • Balanced blends, mainstream rings (48–52): Accordion excels—speed with uniformity.
  • Delicate, aromatic blends: Accordion or careful entubado to avoid over‑compression of fragile seco.
  • Figurados/torpedoes: Entubado or hybrid is safer near the taper; channels can otherwise pinch at the head.

Quality control that actually predicts performance

  • Weight & density spread. Tight ranges indicate consistent bunching; outliers often smoke “off.”
  • Foot read. Clean, even exposure at the foot suggests aligned paths; messy or lopsided feet correlate with uneven lights.
  • Draw testing. Many factories use a draw‑test machine (measures pressure drop in inches of water). Targets vary by size; the point is consistency—too high = tight, too low = airy.
  • Cap structure. A bunched knot under the cap often smokes tight even when the body is perfect.

Troubleshooting (symptom → likely cause → fix at the bench)

Symptom in smokingLikely bunching causeManufacturing fix
Hard draw from first lightCollapsed tubes; over‑tight binder; head knotLoosen binder tension; re‑tube core; refine head shaping
Airy, hot burnToo many open channels; uneven packingAdd filler mass; redistribute folds; adjust binder
Canoeing on one sideFlat plane in book fold; packed cornerBreak up the plane; re‑fold; center density
TunnelingDense core, loose wrapper sideMove ligero inward; even radial density
Relights, sooty aromaOver‑humidified filler at rolling or storageDryer staging leaf; post‑roll rest; storage at 65–67% RH
Centient Method
Engineered calm, by design.

From joinery to air paths, our method removes volatility so the cigars—not the conditions—do the talking.

Storage synergy: why a steady humidor matters to any method

Even the best bunch loses elegance in a volatile box. Keep ~65–67% RH and ~65–70°F, distribute humidification, and leave air paths around boxes and trays. Premium humidors simply make those conditions easier to hold—day after day.

Expert FAQ

Quick, high‑signal answers for collectors.

Is entubado always “better”?
It’s often more consistent, especially with heavier cores or figurados, but a disciplined accordion bunch can smoke just as evenly. Method is a tool; execution and storage decide the outcome.
Can I tell the method by looking at the foot?
Sometimes. Entubado often shows distinct round straws; accordion looks like fine waves; book may show flatter planes. Skilled rollers can make any foot appear tidy, so use this as a hint—not a verdict.
Do machine‑assisted cigars draw worse?
Not necessarily. With proper settings and QC, draw can be excellent. Issues arise when compression is set too high or filler staging is inconsistent—human oversight still matters.
Which method ages best?
Entubado tends to preserve channel integrity over time, which supports consistent combustion as cigars rest. That said, any method kept at steady RH/temperature will age gracefully.
What ring gauge benefits most from entubado?
Large rings (52–56) and tapered heads benefit because axial channels prevent core choking. Slim formats can use accordion effectively with careful binder tension.

Bottom Line

Method shapes the draw; discipline shapes the result. Choose the bunching approach that suits the blend and size, verify with sensible QC, and store in a calm environment. Do that, and the cigar speaks with clarity—today and a year from now.
