Iced Hario Switch

1.

Fold V60 filter and insert into cone, close the switch, pre-heat with boiling water while you are weighing/grinding your beans. Discard water when you are ready to add grounds. Add 150 grams of ice to your mug/carafe.

2.

Grind size: Table salt (about "medium-fine"), just a hair finer than what you’d use for a hot Switch brew - 20 clicks on Comandante C40 for light roasts. Add grounds to brewer and shake a little to flatten coffee bed. Zero scale. Make sure switch is closed.

3.

Start timer. Pour 200g water, starting in the center and circling all around. Pour should be very fast - the idea is to churn up the grounds a lot. Then just wait.

4.

At 8:00 (yes, 8 minutes), open the switch. Give the entire brewer a little swirl to wash grounds off filter walls and flatten the bed. Drawdown will likely take a minute or so.

5.

Pour into a cup that is half full of ice and enjoy. Taste and adjust grind size as needed to dial in. Brew ratio adjustments shouldn’t be necessary. If you are using darker roasted coffee you may want to lower your water temperature somewhat.
