V60 Recipe: Iced Filter Coffee
Sep 01, 2020
Japanese Style Iced Coffee
Personally, this is my favourite way to enjoy a coffee on a hot summer's day. Different from cold brew, Japanese Style Ice Coffee uses hot water to extract all the delicious flavors from the coffee, then cools it down with ice to quickly lock in the flavors. This method of brewing ice coffee is unique from cold brew in that it allows for a lighter, cleaner, and sweeter tasting coffee, and can better extract the complexities of the coffee itself. This particular recipe what we use in our shop was dialed in specifically for our Lū’au blend coffee, but feel free to make incremental adjustments to your liking. The current recipe is developed on the foundation of James Hoffman's ice filter coffee recipe.
Coffee Ratio: To brew our signature Lū’au Blend as an ice filter coffee, we recommend using a coffee:water ratio of 1g:15g (or 65g/1000g, if you're James Hoffman).
Ice Ratio: To lock in the flavors and cool down our coffee quickly, we recommend using about 30% ice. So if you're following our recipe, this means 115g/350g of our coffee will be ice.
We recommend grinding the beans slightly finer than usual to allow for a higher extraction and have a stronger coffee that, when diluted with the ice, will yield a tasty balanced coffee. Look for about the texture of kosher salt.
This is just an extra step to rinse our any paper taste or bleach taste that may be in the filter. Also used to preheat your V60. Usually, we would want to preheat the carafe too, but there is ice in there right now!
Make sure you have a scale underneath the carafe and V60, and keep a timer handy if you have one. Optional: make a little divet in the middle of the coffee bed to help the water saturate the grounds. Reminder: we're going to pour about 240g of hot water.

I don't have a grinder. What do I do?
Don’t worry, we got you covered! If you’re ordering your beans from us online, indicate that you want your beans ground using the drop-down selector on the product page. If you purchased our beans in store, ask our friendly baristas to grind them for you, or bring your whole-bean coffee of choice to your local neighborhood coffee shop!

Why is my brew time is longer than 3 minutes? Why is my brew time is shorter than 2:30?
If your brew time is longer than 3 minutes, it may be over-extracted and taste bitter. This may be the result of beans that are ground too fine. One indication of this if your coffee bed after your brew looks like wet mud. Adjust by grinding a bit coarser. On the other hand, if your brew time is less than 2:30, your coffee might taste a bit acidic and under-extracted. Try grinding a bit finer and adjusting your grind until you reach the target 2:30 - 3:00 minute brew time.

My coffee tastes watered down. What should I do?
While our recipe ensures the coffee to be at the right concentration when its freshly brewed, serving it over more ice means it is inevitable that your ice coffee will be watered down as the ice melts. If your first few sips of your coffee taste watered down, try using a less ice cubes than stated in the recipe (just enough to cool down the hot coffee to room temperature will suffice). If you are able to, use colder ice cubes. Alternatively, try out more creative methods like using coffee ice cubes instead.
