Here’s an easy guide on how to make cold brew coffee at home. Makin cold brew coffee at home is pretty simple – just grind your beans then soak them in big jars on the counter for about 16 hours.

I follow the Stumptown method of 12:64, that’s 12 ounces of freshly ground coffee to 64 ounces of water. This will create a strong concentrate of coffee, so I usually cut the finished product with 1:1 amount of water. You can soak your coffee grounds longer if you want to some really strong coffee concentrate.

Step 1.

Get some coffee, preferably a 12 oz bag of whole coffee beans. I like to use my local Minneapolis roaster, Spyhouse Coffee. You can use already ground if you like as well.

Step 2:

Grind those beans on the coarsest setting possible. Or dump out your bag of already ground beans into a bowl if that’s the route you’re taking.

Step 3:

Fill a 64 ounce jar/pitcher/container of your choosing with filtered water. Dump your coffee into the jar.

Step 4:

Stir the coffee and water together.

Step 5:

Seal the jar or cover the jar with a towel and let it sit out on the counter for the next 16 or so hours.

Step 6:

After 16 hours of room temperature “chilling” the coffee is done. Grab a mesh strainer or other type of sieve, hold the strainer over another container/jar and pour the coffee through the strainer letting the liquid pour through into the second jar/container. This will catch the big chunks of coffee grounds.

Step 7:

Now we’re on to the final step. Rinse the junk out of the first jar/container and place a new coffee filter over it. Pour the first filtered coffee through the coffee filter into the original jar/container. This will filter out the rest of the sludge from the coffee.

And that’s it. Store the finished product in the fridge and enjoy over ice. I like to cut the final result with a 1:1 ratio of water to coffee to dull it down a little bit. Pour the final result over ice and enjoy the summer. A splash of milk of any variety is a nice touch as well.

Mapbox gives you the ability to load custom icons for different points in your maps. When I tried to load a custom icon to a Mapbox map I got the error “SCRIPT5: Access is denied.” in IE 11 – Firefox and Chrome loaded the icon fine. My code was loading an imported image as an object inside a React component like this:

import centerImage from "./images/centerImage.png";

map.on('load', () => {
    map.loadImage(centerImage, (error, image) => {
        if (error) {
            return;
        }
        map.addImage('centerIcon', image);
    });
    ...
});

Updating the image URL parameter to a string URL fixed the problem. I didn’t dig too much into the issue to figure out why this was happening, but passing a valid image string URL was enough to get passed this issue.

map.on('load', () => {
    map.loadImage('/hospital.png', (error, image) => {
        if (error) {
            return;
        }
        map.addImage('centerIcon', image);
    });
    ...
});
