Suprima Instruments Dripper One - SD-1
Precio habitual $40.00Designed by 2x Indonesian Brewers Cup Champion Hiro Lesmana
The SD-1 Coffee Dripper is engineered around three core principles: consistency, repeatability, and durability. By addressing common challenges found in conventional drippers such as unstable flow, inconsistent extractions, and material wear—the SD-1 offers a more reliable and precisely controlled manual brewing experience.
At its core, the SD-1 utilizes a hybrid brewing method: immersion and percolation. This simultaneous integration of two traditionally separate extraction processes creates a unique flavor profile, balancing body and clarity while providing enhanced control over brewing variables.
The defining feature of the SD-1 is its controlled channeling design, which regulates water flow through the coffee bed with exceptional precision. Unlike conventional drippers that often allow uneven channel formation, the SD-1’s geometry actively directs water to improve saturation, optimize extraction yield, and minimize the risk of under- or over-extraction.
The SD-1 Design incorporates
-
Negative channel geometry along the interior walls, promoting even water dispersion.
-
A semi-immersion structure that holds water momentarily before percolation begins, enhancing bloom and ensuring even extraction.
-
An external indentation at the base to ensure a secure fit on most standard servers and carafes, improving stability during brewing.
While the SD-1 is a precision brewing tool, its design prioritizes user experience. The form factor, materials, and geometry are optimized not only for extraction performance but also for durability and ease of use. Manufactured in Indonesia using shatterproof polypropylene (PP), the dripper is both durable and highly thermo-stable. Each design decision reflects a commitment to delivering consistent, professional-level results.
SD1 Basic Starting Recipe by Hiro Lesmana
The SD1 dripper is designed to brew one large cup or two sharing cups.
My ideal starting recipe is either:
18g coffee to 250ml water, or
22g coffee to 300ml water
You might notice that this ratio is a bit dense and that’s intentional. The SD1 works on a semi-immersion method, meaning the extraction rate is slower than your usual percolation dripper. Because of that, a standard 1:15 or 1:16 ratio won’t necessarily yield the best result. Not that it’s wrong - I just personally prefer it this way.
Option 1 : For a Lighter, More Delicate Cup
If you enjoy coffee that’s lighter, elegant, and delicate, a two-pour style works beautifully.
First pour (bloom):
50ml of water for the 18:250 ratio, or
75ml of water for the 22:300 ratio.
Pour evenly, ensuring all grounds are saturated.
Bloom time: Let it sit for at least 1 minute 30 seconds (1:30).
For fresher coffee (1–2 weeks after roast), you can extend the bloom to 2 minutes.
Second pour: Pour the rest of the water in one go, then simply wait for it to draw down.
Yes, a longer bloom is perfectly fine— as long as the coffee tastes great!
For a Balanced, Classic Strength Cup
If you prefer a more traditional strength, try a three-pour style.
First pour (bloom):
50ml (for 18:250) or 75ml (for 22:300).
Let it sit for 40 seconds to 1 minute, depending on coffee freshness.
Second & third pours:
Divide the remaining water into two equal pours.
Each pour should start when the water level is just above the coffee bed.
Example:
If you’re brewing 18g to 250ml, after blooming you’ll have 200ml left.
At around 0:41, pour the first 100ml.
Around 2:00, when the water level drops close to the bed, pour the final 100ml, and let it draw down.
A Note on Drawdown Time
Brewing with the SD1 takes longer than with most percolation drippers and that’s by design. The waiting might test your patience, but as the saying goes, good things take time. I promise the result is worth it.
If the drawdown feels excessively slow and the coffee bed looks muddy, your grind size is too fine.
I intentionally don’t specify grind size or water temperature here — these variables depend on your grinder, coffee, and water composition. Use this recipe as a starting point, and adjust to taste.
