brew
Our coffees are suitable for most brewing methods. Yet we encourage customers to begin with their own method first, then enjoy exploring different recipes, brewers, filter papers, etc. In general, grind size has the biggest impact on the flavor outcome so we suggest users to start with a slightly coarse grind, then go finer when needed.
Here are our recipes of nextlevel pulsar and v60 for those who look for efficient and high extraction brewing methods.
grind
Every dose of coffee grounds contains a spectrum of particle sizes, from fines to boulders. When coffee enthusiasts discuss grind size for certain brewing method, they often use "microns" (µm) which refers to the peak value of a particle size distribution (psd) curve. It is because no two grinders can be identical, and in reality psd varies depending on grinder design, burrset specifications, burrs condition, calibration, alignment, etc. Instead of using vague descriptions such as “medium-fine” or “table salt”, “micron” seems a more effective means of communication.
Finding the right grind size and reducing fines are crucial to a good cup of coffee. Fines reduction can be achieved by installing specialized burrsets, proper burrs alignment or simply using glass dosing vessel as it lets coffee fines to stick along the walls where you can wipe off easily.
pulsar
Pulsar is a “no-bypass” percolation brewer, meaning that all brewing water is passing through the coffee bed. It comes with a dispersion cap that acts like a shower screen and produces steady, even water streams. Pouring techniques are no longer required to make great coffee, and we highly recommend it for its convenience and capability to achieve high and even extraction.
co:llab’s recipe
Filter: standard pulsar filter paper
Dose: 20 grams, medium grind
Water: 340 ml, 96°c to 99°c
Preheat barrel, close valve and fill coffee grounds
Pour to 90 ml and swirl gently. Bloom for 50 sec
Fill to 140 ml then slowly open valve to 75%
(or adjust opening to target total brew time at 3 min ± 15 sec)
Refill 50 ml when water level drops near the “100” mark of the barrel
(swirl gently after each refill)
Finish at 340 ml and swirl gently
v60
V60 is the most popular brewing method of all time. Water percolates through the conical coffee bed and can achieve high extraction yield. Compared to pulsar, v60 is a bypass brewer where water can slip through the filter paper without participating in the brewing process. It also requires pouring with some finesse to make consistent brews. We recommend “two-stage blooming” method that is simple and can ensure even wetting of coffee grounds from the beginning.
co:llab’s recipe
Filter: hario filter paper
Dose: 15 grams, medium to medium-coarse grind
Water: 255 ml, 96°c to 99°c
Poke a hole at the middle of coffee bed before pouring
First bloom: pour 80 ml and swirl gently. Bloom for 30 sec
Second bloom: pour 80 ml and swirl gently
Start pouring when water level remains slightly above coffee bed
Pour slowly in circles and maintain low water level
Finish at 255 ml and swirl gently
(target brew time between at 3 min 45 sec ± 15 sec)
