Hario Water Dripper Tower

Unlike immersion brewing, where coffee grounds sit in water for hours, this tower uses gravity to drip water through the grounds slowly. This process extracts a cleaner, more nuanced flavor profile with less acidity and bitterness, highlighting the delicate notes of your beans.

Yes, the tower features an adjustable valve that allows you to manually control the drip rate. You can fine-tune the speed to suit your preference, which directly impacts the strength and extraction time of your concentrate.

The Hario Cold Process Water Dripper Tower has a capacity of 26 ounces. Because it creates a highly concentrated brew, you will typically dilute it with water, ice, or milk before serving, meaning one batch provides several servings.

Yes, the five-hour brew time is intentional. The slow, steady extraction is what gives the coffee its signature clarity and sweetness, so it is best to set it up in the morning or evening and let it work while you go about your day.

The glass and metal components are designed to be disassembled, which makes cleaning straightforward. We recommend rinsing the glass parts with warm water and mild soap after each use to prevent coffee oils from building up.

You should use a medium-fine grind, similar to what you would use for a standard drip coffee maker. If the grind is too coarse, the water will pass through too quickly; if it is too fine, it may clog the filter.
