I first got here throughout Paragon throughout my journey to South Korea not way back. We had been ingesting a flat white at Requirement Espresso Brewers in downtown Busan when my companion seen that Felix, the proprietor and barista, was beginning to brew espresso by hand utilizing an uncommon stand for his dripper.
Intrigued, I approached him to be taught extra.
“Are you accustomed to Sasa Sestic and his Nucleus Espresso Instruments?“ he requested me as he started pouring water. “These chilling rocks—the Paragon—are one in all their most up-to-date discoveries.“
In fact I knew Sasa, and I had been an enormous fan of Nucleus’ NCD distributor since perpetually, however this was the primary time I had heard of a pourover brewed on a refrigerated steel sphere, so I requested Felix to clarify just a few issues about this new-to-me know-how. He briefly defined how, by brewing the basic hand-drip over the chilled Paragon rocks, it’s attainable to attain a last cup with, amongst different issues, a better aroma and cleaner physique.
One sip of espresso—a heavenly, flowery Colombian Gesha —and I used to be satisfied: I undoubtedly needed to discover a Paragon and begin experimenting a bit with the wonders of this frozen know-how.
Setting Up the Paragon at House
As soon as we received residence, it was lastly time to attempt the Paragon to brew a few my favourite coffees and to be taught extra about this new and thrilling method, evaluating the ultimate cups of my basic recipe with and with out the Paragon.
Paragon is available in a chic, all-black, minimalist bundle. The 2 easy inscriptions on the field are sufficient to pique curiosity. “As much as 40% extra risky compounds than a typical filter espresso,“ guarantees the brief sentence on the opening lid, whereas an extended paragraph on the aspect explains that the Paragon “was created in collaboration with Zurich College of Utilized Science (ZHAW) after researching the impact of temperature on risky aroma compounds preservation and the ensuing sensory taste outcomes in espresso.“
As soon as opened, it regarded extra like one thing out of a chemistry lab than a espresso device, with a sequence of darkish steel parts to assemble (a fast course of that takes just a few minutes to search out the best peak to match your favourite brew set) and two golden “rocks“ that, because the directions counsel, I promptly positioned within the freezer to chill.
At an ordinary freezing temperature of -10 to -20°C, the rocks might be prepared in about an hour—simply the period of time I wanted to evaluate a few introductory movies about Paragon and have a quick chat with a espresso buddy from afar, Peace Sakulclanuwat.
Peace’s Perspective
Peace, a espresso educator at Espresso Undertaking NY and present runner-up on the U.S. Brewers Cup Championship, picked up the Paragon stand and cooling rock from her boss when she was determining which brewing strategies would work finest for her competitors espresso.
“My first impression was superb with the aroma and flavors I received from my espresso,“ Peace says. “The aroma was spectacular, tremendous floral, and extra pronounced than different brewing strategies I had tried earlier than. The flavors had been undoubtedly extra complicated and stylish, particularly the sweetness and readability of the flavors. At that time, satisfied of my resolution, I requested for sponsorship from Nucleus to take part within the Brewers Cup with Paragon. What I appreciated in regards to the Paragon, moreover the nice aroma and the complexity and readability of the flavors, was its modern strategy: I needed to do one thing exterior my consolation zone and that not many had used earlier than to raise the expertise of my total cup high quality and expertise for the judges.“
Peace’s Brew Ideas
Once I requested Peace for brewing ideas with the Paragon, and what enhancements may very well be anticipated from the ensuing cup, she replied: “The notion of aroma might be completely improved. You’ll be able to brew it aspect by aspect with different drippers to check the variations: The aroma of the Paragon will certainly be extra intense and floral, and the sweetness might be enhanced within the espresso flavors. Be mindful, nevertheless, that not all coffees are appropriate for Paragon: higher to make use of coffees with a robust floral character, complicated acidity, and sweetness to get the very best out of that espresso. To begin, you should utilize your standard recipe and dripper, paper filter, and many others., then style the espresso and discover out what variables you need to change to enhance your cup. And experiment with utilizing the cooling stone to dispense all of the pours, or just some pours, to get the very best outcome.“
Earlier than I stated goodbye, I requested Peace if she may counsel a straightforward V60 recipe for me to attempt at residence with the brand new Paragon and my scrumptious Indonesian beans.
“You’ll be able to attempt the recipe I used for my Thai Java and Colombia Maragogype mix at Brewers Cup: 1:14 ratio, 15g espresso and 210g water (94°C or 202°F), divided into 4 even pours 40 seconds aside, with a complete brew time of two:30. For this particular recipe, I used the cooling stone just for the primary two pours to maximise the aroma and flavors of my espresso, however as talked about you possibly can regulate accordingly to the precise espresso used.“
Time to Brew: Spherical One
After thanking Peace, it was lastly time to begin brewing. The rock was correctly frozen (as soon as shaken, I didn’t really feel the inner gel transfer), the steel stand was constructed, my Friedhats washed Rwanda was floor, and the V60 was prepared.
I selected to brew the primary two cups following my customary recipe: 20g of espresso per 300ml of water (93°C), for a complete of 5 pours, together with the blooming.
As steered by one in all Sasa’s tutorials I had seen on-line, I inserted the Paragon into the routine till I poured a few third of the full quantity of water, eradicating the stone instantly after the second pour after which ending the brew often.
As the primary infusion completed, I began the second extraction utilizing precisely the identical recipe, however with out utilizing the Paragon.
As soon as each extractions had been carried out, I may start the comparability.
As Peace and Sasa had hinted at, what struck me was the aroma of the Paragon cup: extra intense, richer, and barely acidic. I may admire how the flavour of the Paragon brew was additionally enhanced, with a rounder, sweeter, and cleaner cup.
It was a powerful outcome, contemplating that the espresso chosen was not notably floral or acidic.
Time to Brew: Spherical Two
After lunch, I brewed one in all my favourite coffees from Indonesia, a pure anaerobic, additionally roasted by Friedhats.
On this session, I made a decision to duplicate Peace’s recipe in its entirety. I additionally carried out a small hack to my filter paper: Throughout the morning brew, I seen that my filter paper was dragging water sideways, displacing the stream from the middle of the server. As steered within the Paragon consumer guide, I lower a small nook on the backside of the filter to facilitate the correct stream of water by means of the filter, then started my brew.
This time, brewing a espresso that I used to be used to brewing nearly every day, the impact of the Paragon was much more superb: The espresso aroma was intense and spicy, and the stone fruit and plantain flavors had been richer and extra distinct.
The Takeaway
Though I brewed a few coffees with out particular floral or acidic notes, as my first day of testing with Paragon got here to an finish, I couldn’t have been extra glad.
The steel stand was handy to assemble and regulate for various espresso machines and servers. The cooling rocks had been simple to make use of and preserve: After every use, I merely wiped them clear by rinsing them with sizzling or chilly water, with out detergent, and dried them with a clear material earlier than placing them again within the freezer. Furthermore, utilizing the Paragon didn’t essentially suggest a change in my brewing routine. It’s an additional step that’s simply relevant to your every day brewing, however on the similar time provides you the chance to experiment with completely different approaches to brewing, relying on the precise espresso you select.
I look ahead to the supply of my subsequent super-light and floral Gesha to discover the potential of the Paragon even additional.
