How To Make Coffee In Riddle Transfer 2
This section provides the complete, step-by-step brewing recipe. Follow these instructions carefully for a reliable and excellent cup every single time.
Equipment And Ingredients You Will Need
Before you start, gather all necessary items. Having everything ready makes the brewing process smooth and enjoyable.
- The Riddle Transfer 2 Brewer (includes the upper brewing chamber and lower serving carafe).
- Fresh, whole bean coffee (medium roast is a great starting point).
- A quality burr grinder.
- A gooseneck kettle for precise water control.
- A digital scale for measuring coffee and water.
- A timer.
- Filtered water, heated to about 200°F (93°C).
Choosing The Right Coffee And Grind Size
The coffee you choose and how you grind it are critical. The Riddle Transfer 2 works best with a medium-coarse grind, similar to what you might use for a Chemex.
A grind that is too fine will over-extract and clog the filter, leading to a bitter and slow drawdown. A grind that is too coarse will under-extract, producing a weak and sour cup. Start with a setting slightly coarser than for a standard pour-over and adjust based on your taste. Freshly ground beans are non-negotiable for the best flavor.
Step-By-Step Brewing Instructions
Now, let’s walk through the brewing process. Pay close attention to the swirling technique, as it is the core of the Riddle Transfer 2 method.
Step 1: Preheat And Prepare
Begin by heating your water. While it heats, place a paper filter in the upper chamber of the brewer. Rinse the filter thoroughly with hot water. This removes any paper taste and preheats the entire brewer. Discard the rinse water from the lower carafe.
Step 2: Measure And Add Coffee
Weigh your coffee. A good starting ratio is 1 gram of coffee to 16 grams of water. For a full carafe (about 500ml), use 31 grams of coffee. Add the ground coffee to the pre-rinsed filter in the upper chamber.
Step 3: The Initial Pour And Bloom
Start your timer. Pour just enough hot water (roughly twice the weight of your coffee) to saturate all the grounds. For 31 grams of coffee, use about 62 grams of water. Gently swirl the upper chamber to ensure all grounds are wet. Let it bloom for 30 to 45 seconds.
Step 4: The Main Pour And Swirl
After the bloom, slowly pour the remaining water in a circular motion. Aim to finish pouring by the 1:15 minute mark on your timer. Now, here is the key step: securely place the upper chamber onto the lower carafe. Pick up the entire assembled brewer and begin swirling it gently but steadily. Swirl for about 20 to 30 seconds. This agitation ensures even extraction.
Step 5: Drawdown And Serve
Place the brewer back on your counter or scale. Allow the coffee to draw down completely through the filter into the carafe. The total brew time, from the start of your pour to the end of the drawdown, should be between 3:30 and 4:30 minutes. Once dripping stops, remove the upper chamber. Your coffee is ready to serve from the elegant lower carafe.
Mastering The Swirling Technique
The swirl is what sets this brewer apart. It’s not a vigorous shake, but a gentle, horizontal rotation. Think of stirring a pot without a spoon, using a smooth wrist motion. The goal is to keep the coffee slurry moving evenly across the entire bed of grounds. Practice this motion with just water first to get a feel for the weight and balance. A consistent swirl leads to a uniform extraction and a cleaner, more balanced cup.
Advanced Tips For Perfect Extraction
Once you’ve mastered the basic method, you can fine-tune your brew. These adjustments help you dial in the flavor to match your personal preference.
Adjusting Brew Variables For Taste
If your coffee tastes bitter or harsh, it is likely over-extracted. To fix this, try a coarser grind size, use slightly cooler water, or reduce your swirl time. If your coffee tastes sour or weak, it is probably under-extracted. Correct this with a finer grind, hotter water (up to 205°F), or a longer, more vigorous swirl. Always change just one variable at a time so you can understand its effect.
Water Quality And Temperature
Water is the main ingredient in your coffee. Using filtered water makes a significant difference, as chlorine and heavy minerals can affect taste. The ideal water temperature is between 195°F and 205°F (90°C to 96°C). If you don’t have a thermometer, let your boiled water sit for 30 seconds before pouring.
Cleaning And Maintaining Your Brewer
Proper care extends the life of your Riddle Transfer 2. After each use, discard the paper filter and grounds. Rinse both the upper chamber and lower carafe with warm water. Occasionally, wash them with mild soap to remove coffee oils. Ensure all parts are completely dry before reassembling for storage. Avoid using abrasive scrubbers that could scratch the glass.
Troubleshooting Common Issues
Even with careful preparation, you might encounter some issues. Here are solutions to common problems.
Slow Or Stalled Drawdown
A very slow drawdown (over 5 minutes) usually indicates your coffee grind is too fine. It can also be caused by swirling too aggressively, which forces fines to the bottom of the filter and clogs it. Adjust your grinder to a coarser setting and ensure your swirl is gentle and horizontal, not vertical.
Weak Or Watery Coffee
If your coffee lacks body and flavor, check your coffee-to-water ratio first. Make sure you are using enough coffee. Next, assess your grind size; it may be too coarse. Finally, ensure your water is hot enough and that you are swirling sufficiently to agitate all the grounds.
Uneven Or Muddy Coffee Bed
After the drawdown, the used coffee grounds should form a relatively flat, even bed. If you see channels, holes, or a muddy texture, your initial pour or swirl was uneven. During the bloom and main pour, try to wet all grounds evenly. The swirling step is designed to fix this, so focus on a consistent, full-coverage swirl.
FAQ About The Riddle Transfer 2
What Is The Best Grind For Riddle Transfer 2?
The best grind size is medium-coarse, comparable to coarse sea salt or a Chemex grind. It should be noticeably coarser than a standard V60 pour-over grind. This allows for a good flow rate while still allowing for proper extraction during the immersion and swirl phase.
Can I Use The Riddle Transfer 2 Without Swirling?
You can, but you will not get the intended results. The swirling action is fundamental to the brewer’s design. It replaces manual pouring agitation, ensuring all coffee grounds are evenly saturated and extracted. Skipping the swirl will likely lead to an uneven and underwhelming cup.
How Is It Different From A French Press?
Both are immersion brewers, but the Riddle Transfer 2 uses a paper filter, resulting in a clean, sediment-free cup like a pour-over. The French Press uses a metal mesh filter, which allows oils and fine particles through, giving a heavier body. The swirling technique of the Riddle also promotes a more uniform extraction than the simple steep-and-plunge of a French press.
What Coffee Roast Works Best?
You can use any roast you enjoy. However, medium and light roasts often shine in the Riddle Transfer 2 because the clean extraction highlights their nuanced acidity and complex flavors. Darker roasts also work well, producing a smooth and rich cup without excessive bitterness, thanks to the controlled extraction.
Where Can I Buy Replacement Filters?
Replacement paper filters are widely available online from coffee equipment retailers and directly from the manufacturer’s website. Ensure you purchase the correct size designed specifically for the Riddle Transfer 2 brewer for the best fit and performance. They are typically sold in packs of 100.
Mastering how to make coffee in the Riddle Transfer 2 is a rewarding skill for any coffee enthusiast. The unique swirling method might feel unfamiliar at first, but with a little practice, it becomes a simple and meditative part of your routine. The consistent, clean, and flavorful results are well worth the effort. Remember to start with the basic recipe, use fresh coffee and good water, and focus on that gentle swirl. From there, you can experiment with grind size and coffee origins to find your perfect brew. Enjoy the process and the exceptional coffee it produces.
