# Brewing Coffee with the Hario Syphon Technica

A one-minute walkthrough of vacuum-pot brewing on the Hario Syphon Technica using 28 g of medium-ground coffee and 450 ml of hot water — from seating the upper chamber over a halogen beam heater to stirring the grounds and pulling the pot off the heat for drawdown.

## Prep

| Tools & materials | Spec / notes |
| --- | --- |
| Coffee beans | 28 g (medium grind) |
| Heated water | 450 ml |
| Hario Syphon brewer | 1 unit (Technica model) |
| Heat source | 1 halogen beam heater / burner |
| Coffee grinder | 1 unit (Baratza Vario-W shown) |
| Paddle or stir stick | 1 unit |

## Steps

1. Grind 28 g of coffee beans to a medium grind. (~00:05)

2. Heat 450 ml of water and pour it into the lower bowl of the syphon. (~00:07)

3. Fit the upper bowl (with the filter installed) into the lower bowl. (~00:15)

4. Turn the heat source on beneath the lower bowl. (~00:19)

5. Once the water rises into the upper bowl, stir the hot water, tip in the ground coffee, and stir again to wet all the grounds. (~00:27)

6. Take the syphon off the heat so the cooling lower bowl draws the brewed coffee down through the filter. (~00:40)

7. Once the coffee has finished drawing down, lift off the upper bowl and serve. (~00:57)

## Grinding and Preheating (~00:04)

Weigh out 28 g of beans and grind them medium. Preheating 450 ml of water in a kettle before pouring it into the lower glass bowl saves time over heating cold water on the burner.

## Rising Water and Immersion (~00:17)

Seat the upper bowl (with filter hooked in) into the lower bowl and switch on the halogen beam heater. Once vapour pressure pushes the water up into the top chamber, give the water a quick stir, tip in the coffee grounds, and stir again so every bit of coffee is wetted.

## Vacuum Drawdown (~00:39)

Slide the syphon off the heat source. As the lower globe cools, the drop in pressure pulls the brewed coffee back down through the filter, leaving a neat bed of grounds above. Lift off the upper bowl and pour.

## To verify

- A jump cut skips the steep between stirring the coffee and pulling the syphon off the heat, so the exact brew time isn’t given.
- The video doesn’t state the exact kettle temperature of the 450 ml of water.
