Our guest blogger, Randy Pang is a barista trainer who brews with a mindful approach. In this piece, Randy tackles a common mistake many first-time sifters make and offers a clear suggestion on how to prevent it - to get the best results with the KRUVE Sifter.
Without a doubt, when it comes to coffee, measurement matters and the importance of using a consistent grind size can impact the results very dramatically. However, one cannot change grind size in isolation. There are other important factors to consider.
Things to Consider
Though people from all over the world are jumping on board to use this amazing innovation, I suspect many are using it incorrectly. This thought came about when I first started using the KRUVE Sifter. A while back, I looked up several YouTube videos of people using the device for the first time and listened to their opinions about it. A good deal of them would suggest that while KRUVE increased cup clarity, it also produced a noticeably 'weaker' cup. However, this is most certainly due to an incorrect understanding of grind manipulation. Hopefully, I can alleviate some of the frustrations that might come from this confusion.
"Changing your grind size changes the strength of your brew."
All else being constant, changing your grind size changes the strength of your brew. Whether your grinder produces more boulders or fines, when you eliminate the outlying particles, you are changing the strength (TDS%) of your coffee. For example, by eliminating all boulders (larger particles) on an average dose and replacing them with the particles in the lower ranges, you are increasing extraction because the grind sizes are now smaller. The contrary is also true, by eliminating the fines (smaller particles), you are decreasing extraction. By eliminating both fines and boulders, you are now drastically changing the strength of your coffee.
Making Proper Adjustments
To make the best cup, baristas need to adjust brew time accordingly.
This change matters a whole deal if all we are doing is manipulating the grind size and applying it to a standard recipe. The recipe must change according to the new findings of the sifted cup. Your sifted cup may be stronger or weaker, depending on how you manipulated the grinds. My point here is not whether your sifted cup tastes better, but that a sifted cup changes the strength of any given recipe you have been using with a particular grinder. If your grind is going to change, it is likely that your recipe will have to change as well.
"If your grind is going to change, it is likely that your recipe will have to change as well."
While I don’t intend to address the various brew methods in this blog, I do want to point out that using the KRUVE Sifter involves more than mere grind manipulation. Yes, grind manipulation is what the KRUVE Sifter does, but to have a narrow view of grind manipulation as the sole factor, is, in my opinion, an abuse of its usage. I want to suggest that the KRUVE Sifter is a portal for many lay coffee drinkers and enthusiast to participate in the interestingly complicated process of crafting the perfect cup. Using the KRUVE Sifter opens new doors to better understand what is happening to our coffee as it comes in contact with water in which grind manipulation is one important aspect of a wide array of variables.
Thought of the day: People usually notice a weaker cup when using the @kruveinc sifter, even though sifting in theory provides a more even extraction. However you are losing/changing a majority of your brew's surface area when you sift out the fines. If you are only using the middle tray on your Kruve, perhaps you may have to increase your dosage. #thoughtoftheday #coffeeholic #research #coffeealltheway
I hope drawing attention to this simple fact will challenge all KRUVE Sifter users to think critically about all the parts of their brewing process. To isolate any one variable without considering the broader implications is to hold a reductionist view of coffee brewing methodology. Yes, changing the grind is important, but changing other variables to complement that change are also crucial.
