Learn how to pick the perfect filter basket size for your OutIn Nano. Compare 6g-8g and 16-18g baskets to match your espresso style and dose.

When you own a portable espresso machine like the OutIn Nano, one of the most important decisions you'll make is choosing the right filter basket size. The basket determines how much coffee you can dose, which directly affects the flavor, strength, and crema of your espresso. With multiple options available, it can be confusing to know which one suits your needs best.

In this guide, we'll break down the differences between the available filter baskets for the OutIn Nano, explain how basket size impacts your brew, and help you decide whether a 6g-8g basket or a 16-18g basket is right for you. By the end, you'll be equipped to make an informed choice that elevates your portable espresso experience.

Understanding Filter Basket Sizes

Filter baskets come in various sizes, typically measured by the amount of ground coffee they hold. The most common sizes for portable espresso machines are 6g-8g (single shot) and 16-18g (double shot). The size you choose affects the coffee-to-water ratio, extraction time, and overall flavor profile. A smaller basket is ideal for a quick, concentrated shot, while a larger basket allows for a more balanced and nuanced espresso.

For the OutIn Nano, the standard basket size is designed to hold around 6-8 grams of coffee, which is perfect for a traditional single espresso. However, if you prefer a stronger, more robust cup or want to brew a double shot, you might consider upgrading to a larger basket. Understanding these differences is the first step in tailoring your espresso to your taste.

  • 16-18g baskets: perfect for double shots and richer flavor extraction

The 6g-8g Filter Basket: Single Shot Simplicity

The Nano Portable Espresso Machine Filter Baskets Kit (6g-8g) is the standard option that comes with most OutIn Nano machines. This basket is designed for a single shot of espresso, typically yielding about 30ml of liquid. It's perfect for those who enjoy a quick, intense espresso without the need for a larger dose. The smaller size also means less coffee is used per brew, which can be more economical in the long run.

Using a 6g-8g basket is straightforward: fill it with finely ground coffee, tamp evenly, and lock it into the portafilter. The result is a concentrated shot with a thick crema, ideal for sipping straight or adding to milk-based drinks like a macchiato. If you're new to espresso making, this basket is a great starting point because it's forgiving and easy to master.

The 16-18g Basket: Double Shot Power

For those who crave a more substantial espresso, the Nano Portable Espresso Machine Basket Plus (16-18g) is a game-changer. This larger basket allows you to dose 16-18 grams of coffee, producing a double shot of espresso (around 60ml). The increased coffee amount results in a fuller body, more complex flavors, and a richer crema. It's perfect for making Americanos, lattes, or any drink that requires a stronger espresso base.

One of the main advantages of the 16-18g basket is the ability to experiment with different coffee beans and grind settings. With a larger dose, you have more room to adjust the extraction to highlight specific tasting notes. However, it requires a coarser grind and a longer extraction time, so you'll need to fine-tune your technique to avoid over-extraction.

How Basket Size Affects Your Espresso

The size of your filter basket directly influences the pressure and flow of water through the coffee grounds. A smaller basket creates a thicker puck, which increases resistance and can lead to slower extraction. This often results in a more intense and concentrated shot. Conversely, a larger basket with more coffee creates a thinner puck, allowing water to flow more quickly, which can produce a lighter-bodied espresso with more clarity.

Choosing the right basket size also depends on your brewing preferences. If you enjoy a bold, strong espresso, the 6g-8g basket might be your go-to. If you prefer a smoother, more balanced cup with room for flavor complexity, the 16-18g basket is the better choice. Understanding these dynamics helps you tailor your brew to your exact taste.

Choosing the Right Basket for Your Needs

When deciding between the 6g-8g and 16-18g baskets, consider your typical coffee consumption. If you usually make a single espresso for yourself, the 6g-8g basket is convenient and efficient. If you often brew for two or enjoy larger drinks, the 16-18g basket will save you time by allowing you to pull a double shot in one go.

Another factor is the type of coffee you prefer. Light roasts often benefit from a larger dose to bring out their delicate flavors, while dark roasts can shine with a smaller dose for a punchy espresso. Additionally, think about the accessories you already own. For instance, the OutIn Nano Protective Case is essential for carrying your machine and baskets safely, and having multiple baskets lets you switch between single and double shots on the go.

  • Consider your daily caffeine needs: single vs. double shot
  • Think about the roast profile of your favorite beans
  • Check compatibility with your current accessories

Tips for Using Different Basket Sizes

Once you've chosen your basket, it's important to adjust your grind size and tamping pressure accordingly. For a 6g-8g basket, use a fine grind and a firm tamp to ensure proper extraction. For a 16-18g basket, a slightly coarser grind and a lighter tamp can help prevent over-extraction. Always experiment and taste as you go to find the perfect balance.

Also, remember to keep your baskets clean and dry after each use. Residual coffee oils can affect the flavor of your next brew. A quick rinse and air dry will keep your baskets in top condition. If you're planning to travel, consider investing in a protective case to keep your baskets and machine safe from damage.

Choosing the right filter basket size for your OutIn Nano is a personal decision that depends on your taste preferences and brewing habits. Whether you opt for the 6g-8g basket for a quick single shot or the 16-18g basket for a richer double, understanding the impact of basket size will help you craft the perfect espresso every time.
