V-Fold 155: The Definitive Kalita Wave Filter Former (Why 38.3°?)

What Is V-Fold 155?

V-Fold 155 is a precision filter paper former designed for Kalita Wave 155 papers. It quickly restores stacked papers to a consistent target geometry of 38.3°, stabilizing flow, reducing fines carry-over, and cutting down variables before extraction even begins.

Why 38.3° Matters

Wave papers are pleated and should meet the flat-bottom dripper walls at a repeatable contact angle. Our validated target of 38.3° provides reliable support and drainage while helping fines adhere to the paper wall rather than entering the cup—yielding a cleaner flavor profile with less bitterness and muddiness.

The Stacking Problem with Wave Papers

Manufacturing and stacked packaging introduce subtle angle deviations across sheets. The result can be:

• Inconsistent flow from sheet to sheet, batch to batch;
• Fines accumulation at certain pleats, leading to partial clogging;
• Poor repeatability under identical recipes and pouring styles.

Pre-forming with V-Fold normalizes papers back to 38.3°, narrowing variation before brewing.

Three Stability Gains from Pre-Forming

1. More stable drawdown: unified geometry → more predictable resistance and flow.
2. Cleaner cups: fines tend to stay on the paper wall instead of entering the beverage.
3. Higher repeatability: closer curves and flavors across repeated brews and recipes.

How to Use (3 Simple Steps)

1. Form: place the Wave 155 paper into V-Fold 155 and press gently for 1–2 seconds.
2. Rinse: wet the paper and dripper as usual, keeping the paper seated against the wall.
3. Brew: proceed with your recipe and observe smoother, more predictable drawdown.

Compatibility & Specs

• Filter papers: Kalita Wave 155 (and most third-party Wave-style 155 papers).
• Target angle: 38.3° (pre-formed geometry).
• Version: current release is 155-only; 185 version is under planning.
• Build: lightweight, durable, engineered for daily use.

Care & Maintenance

• Store dry; avoid prolonged heat and harsh solvents.
• Rinse or wipe with mild detergent; air dry before storage.

FAQ

Q1: Does forming change total brew time?
It makes flow more stable. Total time still depends on grind, recipe, and pouring.

Q2: Does it reduce fines?
Forming doesn’t alter grind distribution, but it reduces fines carry-over into the beverage, leading to cleaner cups.

Q3: What about 185?
Current version targets 155; 185 is under planning with the same principles.

Q4: Do I need to form every time?
Yes—pre-forming for 1–2 seconds before each brew yields the most consistent results.
