The 187

187 mL of sparkling wine. A bottle, a label, a closure, sometimes a capsule—and a question: does every piece earn its place?

The object

A miniature bottle can carry a full-size performance.

Some sparkling-wine splits use a plastic, cork-shaped twist closure. It can recreate the visual cue of a traditional sparkling bottle. But the 187 mL format is not married to that choice: pressure-rated bottles are commercially offered with crown and ROPP finishes, among other systems.

“The plastic cork-shaped stopper is one closure choice among multiple technically viable closure systems.”

What we’re asking

  1. What function does the closure perform?
  2. Which alternatives meet the same technical requirements?
  3. What changes for bottling, service, disposal, and cost?
  4. What part is function—and what part is theater?

This is an investigation, not a claim that every producer can switch systems overnight. Neck finishes, pressure, liners, machinery, and recovery systems all matter.
