Craving iced coffee on the go? Learn how to make cold espresso with your OutIn Nano, plus tips for the best cold brew alternative.
When the temperature climbs, a hot espresso shot might not be your first choice. But that doesn't mean you have to give up your favorite portable espresso maker. With a few simple adjustments, you can turn your OutIn Nano into an iced coffee machine that delivers refreshing, cold espresso anywhere. Whether you're at the beach, on a hike, or just commuting, these tips will help you craft the perfect cold brew alternative.
In this guide, we'll show you how to make cold espresso with your Nano, from choosing the right beans to chilling your drink without diluting it. You'll also learn how to use your Nano to create a cold brew-style concentrate that's perfect for travel.
Why Cold Espresso is the Ultimate Cold Brew Alternative
Cold brew is beloved for its smooth, low-acidity flavor, but it takes 12-24 hours to steep. When you're on the go, that's not practical. Cold espresso, on the other hand, is ready in under a minute. By pulling a shot directly over ice, you get a concentrated, bold coffee that can be diluted to your liking. It's a quick and easy cold brew alternative that still delivers rich flavor.
Plus, using your OutIn Nano for iced coffee means you don't need any extra equipment. No bulky cold brew makers or filters. Just your Nano, fresh beans, and ice. It's the ultimate travel-friendly way to enjoy cold coffee.
- Cold espresso is ready instantly, unlike traditional cold brew.
- You control the strength and flavor by adjusting the dilution.
- Your Nano is compact and portable, so you can make iced coffee anywhere.
Choosing the Right Beans for Cold Espresso
The beans you choose play a big role in the final taste of your iced espresso. For a cold brew alternative, you want beans that are naturally sweet and low in acidity. A medium roast with chocolatey or nutty notes works beautifully. Our Guatemala Single Origin - Medium Roast is a fantastic choice. It offers a balanced profile with hints of cocoa and a smooth finish that shines when chilled.
If you're feeling adventurous, try a blend with fruity or floral notes for a more complex iced drink. Just remember that cold temperatures mute some flavors, so opt for beans you enjoy at their boldest.
Grind Size and Dose: Getting it Right
For cold espresso, you want a fine grind, similar to what you'd use for a regular shot. The Nano's built-in grinder (if you have the model) or your own grinder should produce a consistency like table salt. If your grind is too coarse, the water will pass through too quickly, resulting in a weak, sour shot. Too fine, and you'll clog the basket.
As for the dose, the Nano's standard basket holds about 14-16 grams. If you prefer a stronger concentrate, you can use the Nano Portable Espresso Machine Basket Plus (16-18g) to pack more coffee. This is especially useful when you plan to pour over ice and want the espresso to stand up to the dilution.

The Ice-First Method: Pull Your Shot Directly Over Ice
The simplest way to make iced espresso is to fill your cup with ice, then pull your shot directly over it. The hot espresso instantly chills, locking in the aromatics and preventing over-extraction. Use a heatproof glass or a durable cup like the Titanium Coffee Cup, which can handle temperature changes without cracking.

One tip: don't overfill the cup with ice. You want enough to chill the espresso but still leave room for milk or water if you like. Start with a handful of ice cubes, pull your shot, and stir gently to cool it evenly.
Chill Your Nano and Water for Extra Cold Espresso
If you're really serious about cold espresso, you can pre-chill your Nano's water tank and even the machine itself. Fill the tank with cold water from the fridge, and store your Nano in a cool place before use. This ensures the water is as cold as possible before it hits the coffee, which helps produce a smoother, less bitter shot.
Another trick is to freeze your coffee beans before grinding. Cold beans grind more consistently and produce a better extraction. Just don't leave them in the freezer for too long, as they can absorb odors.
Make a Cold Brew Concentrate with Your Nano
Did you know you can use your Nano to make a cold brew-style concentrate? It's not traditional cold brew, but it's a close approximation. Pull two or three shots of espresso into a small bottle, then add cold water at a 1:1 or 1:2 ratio. This creates a concentrate that you can store in the fridge and mix with milk or water later.
This method is perfect for travel. You can prepare the concentrate in the morning, pack it in a thermos, and enjoy iced coffee throughout the day without needing your Nano again. Just remember to keep it cold.
Don't Forget the Accessories: Tote and Bean Tray
To make the perfect iced espresso on the go, you'll want a few accessories. The OutIn Rebrew Bean Tray is handy for storing your freshly ground beans, so you can carry just the right amount without mess. And if you're heading out for a day trip, the Gift Tyvek Tote For Portable Espresso Machine keeps your Nano and accessories organized and protected.
These small additions make it easier to enjoy cold espresso anywhere, whether you're at a picnic or in a hotel room.
Making cold espresso with your OutIn Nano is easy and rewarding. By choosing the right beans, adjusting your grind, and using the ice-first method, you can enjoy a refreshing iced coffee that rivals any café. Don't forget to experiment with different beans and ratios to find your perfect cup. For a great starting point, try the Guatemala Single Origin - Medium Roast, and pair it with a Titanium Coffee Cup for the ultimate travel experience.
