# Aero Temper

Description: Aero Temper is a planned Brew Supply tool for pressing an AeroPress paper filter into the cap evenly and reducing folds or creases before brewing.

Aero Temper is a planned filter-preparation tool intended to make paper-filter seating more even and repeatable before an AeroPress brew begins.

## Problem It Solves
A paper filter can sit unevenly, lift at an edge, or develop a crease while it is placed and wetted. Those small setup differences are easy to overlook because they happen before coffee and water enter the brewer. Aero Temper explores whether one simple, repeatable pressing action can make filter placement less dependent on fingertips, cap angle, and hurried competition setup.

## Variable It Controls
The intended control is filter seating: how evenly the paper lies against the cap and whether visible folds or raised edges remain before assembly. That is a preparation variable, not a direct measurement of flow, extraction, or cup quality.

## How It Works
- Place the paper filter in the AeroPress filter cap using the normal dry or rinsed workflow.
- Use the tool to apply an even seating action across the filter rather than pressing isolated points with a fingertip.
- Inspect the edge and center before attaching the cap; the intended endpoint is a visibly flat, consistently seated filter.
- Keep filter type, rinse method, and cap handling constant when comparing the concept with the normal setup.

## When To Use It
- When filter folds or inconsistent seating appear during fast setup.
- When a brewer wants the filter-preparation step to be as deliberate as dose, water, and timing.
- When repeated practice needs one easy visual endpoint before the brewer is assembled.

## What It Does Not Solve
- It does not prove that a flatter-looking filter changes extraction or flavor.
- It does not replace the filter cap, choose a filter material, or correct a damaged paper.
- It does not control grind, water, agitation, bypass, pressing, or service.
- It adds a step, so it is less useful when normal filter placement is already fast and consistent.

## Print Guidance
- The concept is planned; dimensions, material guidance, and print tolerances are not yet a public release specification.
- Any future version must avoid sharp edges or geometry that can tear the paper or damage the cap.

## Version Status
- Planned

## Competition Relevance
The concept is most relevant where setup speed makes small filter-placement mistakes more likely and the brewer wants a repeatable pre-brew check.

Brew Supply is independent and not affiliated with AeroPress or the World AeroPress Championship. Planned printed parts must be validated for fit, heat, food-contact, and safe use before they are treated as finished brewing hardware.

## FAQ
### Is Aero Temper available to download?
No. Aero Temper is a planned concept. Brew Supply has not published a final product-specific file or release date.

### Does filter tamping improve AeroPress coffee?
That has not been established. The intended benefit is a more repeatable filter-seating workflow, not a guaranteed sensory result.

### Is this the same as tamping espresso?
No. The concept concerns seating a paper filter in an AeroPress cap. It does not compress a coffee puck or reproduce espresso preparation.
