Why Quality Beans are the Secret to Great Cold Brew

Before we dive into the brewing process, let's talk about the single most important ingredient: the coffee beans. The cold brew method is celebrated for its ability to highlight the natural sweetness and subtle notes of the coffee. Because there is no hot water to flash-extract flavors and oils, the process is much gentler. This means that the quality of your beans is on full display.

Using fresh, high-quality beans is non-negotiable for a delicious result. At Door County Coffee, we use 100% Specialty Grade 1 Arabica beans, which represent the top 2% of coffee available worldwide. This commitment to quality ensures that every bag is packed with the best possible flavor. When you use premium beans for your cold brew, you’ll notice a significant difference. The final product is cleaner, sweeter, and free from the papery or stale taste that comes from lesser-quality coffee. It's the foundation upon which perfect cold brew is built.

Choosing Your Grind: The First Step to Success

For cold brew, you need a coarse grind. Think of the consistency of coarse sea salt or breadcrumbs. A grind that is too fine will over-extract, resulting in a cloudy and bitter concentrate. It can also create a muddy sludge at the bottom of your brewing container, making it difficult to filter properly.

A coarse grind allows water to circulate evenly around the coffee grounds, extracting flavor slowly and consistently. This slow, gentle extraction is what gives cold brew its signature smooth, low-acid profile. If you have a grinder at home, set it to its coarsest setting. If not, you can always select the "coarse" grind option when ordering from Door County Coffee to ensure you have the perfect foundation for your brew.

The Easiest Way to Brew: The Toddy Cold Brew System

While you can make cold brew in a simple mason jar, using a dedicated system makes the process cleaner, easier, and more consistent. We recommend the Toddy Cold Brew System, a favorite among both home brewers and professional coffee shops for decades. It’s designed specifically for this brewing method, taking all the guesswork out of creating the perfect concentrate.

The Toddy system consists of a brewing container, a handle, two reusable filters, and a glass decanter with a lid. Its brilliance lies in its simplicity and effectiveness. The dual-filtration system ensures that no sediment makes its way into your final concentrate, giving you an incredibly clean and smooth coffee. It’s the ideal tool for anyone looking to master cold brew at home.

How to Use the Toddy Cold Brew System

Making a batch of cold brew concentrate with the Toddy is simple. Here’s a step-by-step guide:

1. Prepare the System: Insert the rubber stopper into the bottom of the brewing container from the outside. Dampen the circular felt filter and place it inside at the bottom, pressing it gently into the recess.
2. Add Coffee and Water: Pour 1 cup of water into the brewing container. Then, add 6 ounces of your coarsely ground Door County Coffee. Slowly pour 3 more cups of water over the grounds in a circular motion, ensuring all the grounds are saturated.
3. Settle the Grounds: Using a spoon, gently press down on the grounds to make sure they are all wet. Do not stir. Stirring can agitate the grounds and lead to a bitter brew.
4. Steep Patiently: Let the coffee steep for 12 to 24 hours at room temperature. A 12-hour steep will produce a classic, smooth cold brew. For a richer, more intense concentrate, you can let it steep for up to 24 hours. Feel free to experiment to find your perfect steeping time.
5. Drain the Concentrate: When your steep is complete, place the brewing container on top of the glass decanter. Carefully remove the rubber stopper. The coffee concentrate will begin to filter into the decanter below. This process can take about 20-30 minutes.
6. Store and Enjoy: Once the concentrate has finished draining, place the lid on the decanter and store it in your refrigerator. Your cold brew concentrate will stay fresh for up to two weeks.

Beyond the Basics: Flavoring Your Cold Brew

One of the best parts of making your own cold brew is the ability to experiment with different flavors. While a classic, unflavored dark roast makes a fantastic cold brew, using flavored coffee beans can elevate your experience to a whole new level. The cold brewing process is gentle enough to pull out the subtle flavor infusions without them tasting artificial or overpowering.

At Door County Coffee, we offer over 70 varieties, giving you endless possibilities. Here are a few favorites that shine as cold brew:

• Peanut Butter Crunch: Imagine a smooth, nutty coffee with hints of cookie goodness. This flavor creates a decadent cold brew that tastes like a dessert but is perfect for starting your day.
• Coconut Caramel: This blend brings a tropical and sweet twist to your cup. The creamy coconut and rich caramel notes are exceptionally refreshing over ice, making it an ideal choice for a summer afternoon.
• Cherry Creme: For something truly unique, try this flavor. The sweet, fruity notes of cherry blend beautifully with a creamy vanilla finish. It makes a bright and delightful cold brew that is both surprising and delicious.

Don't be afraid to try your favorite flavored coffee in a cold brew batch. You might just discover a new go-to drink.

How to Serve and Enjoy Your Cold Brew

You've made your delicious concentrate—now what? Remember, this is a concentrate, so it's much stronger than regular drip coffee. You'll want to dilute it before drinking.

• The Classic Cold Brew: The standard ratio is one part cold brew concentrate to one part water. Fill a glass with ice, pour in your concentrate, and top it off with an equal amount of cold, filtered water. Give it a stir and enjoy.
• Make it a Latte: For a creamier drink, swap the water for milk or your favorite non-dairy alternative like oat or almond milk. A 1:1 ratio of concentrate to milk is a great starting point.
• Sweeten it Up: Cold brew’s low acidity means it’s naturally sweeter than hot coffee, but you can always add your favorite sweetener. Simple syrup works best as it dissolves easily in cold liquid.
• Get Creative: Use your cold brew concentrate as a base for coffee cocktails, pour it over ice cream for an affogato, or add it to smoothies for a caffeine kick.

Making perfect cold brew at home is a simple and rewarding process. It starts with choosing high-quality beans, getting the grind right, and using a reliable system like the Toddy. From there, you can explore a world of flavor and find the perfect cup for you.
