Coffee Types

The cold brew process works well with various coffee bean types - light roasts, dark roasts, single origin, blends, etc. The low temperature helps minimize bitterness and acidity.

Coffee Quality

The Dorothy produces smooth, mellow cold brew coffee with deep flavor notes and pleasant aroma. The glass carafe allows you to watch the coffee extract and darken.

Tornado Spinning Technology

This technology is what enables the Dorothy to produce cold brew coffee in just 15 minutes.

Two Speed Settings

The Dorothy brewer offers two speed settings to customize your cold brew. The higher speed creates a stronger brew in less time, while the lower speed produces a smoother brew. This flexibility allows you to personalize your coffee experience to your preference.

Ground Removal Cup
