Love these shout-outs from our retail partners! If you’re in/around Evans, GA, check out Goat Kick Coffee’s shop (online too: goatkickcoffee.com). They're making cold brew the right way!

Andrew and the folks at Metro on the Move unboxed and reviewed Rumble Go while they were out camping on a cold rainy day. Despite pretty rough conditions, they still gave the filter top marks! Have a watch on their youtube channel Metro on the Move: youtu.be/CjaNnxPZSR4

Our Rumble Go filters come with a detachable base which make it a cinch to clean by hand. (and it's also dishwasher-friendly!) therumblejar.com/products/ru…

If you're a bottled cold brew drinker, there's a good chance you'll break even cost-wise on your *very first* batch with our 64oz Rumble Jar filter. (And there's a really good chance it tastes better too!) - therumblejar.com/products/ru…

We're kicking off the unofficial start of summer with another La Colombe roast. This time it’s their medium roast Nizza, recommended by a friend who swears by it for cold brew. Enjoy the long weekend! LaColombe.com/products/nizza

Curious how best to wash your Rumble Jar filter by hand? Of course our filters are dishwasher-friendly, but in case you need to hand-wash them, our recommendation is to use one of these "sponge on a stick" devices (e.g. Scotch Brite Dishwand shown here).

Combine 1 cup of cold brew + 1 cup of any milk (unsweetened) + 1 tablespoon of pumpkin puree + 1 tablespoon of maple syrup (but any sweetener works) + a dash of vanilla extract + a sprinkle of cinnamon. Then just whisk it or blend it until it's frothy.
