The B3 HYBRID is a completely unique and innovative filter designed by Sibarist for conical drippers that gives a hybrid between flat bottoms and cone brewing, made with the B3 filter paper technology.

The hybrid shape encourages flow through the dripper by providing a faster and higher extraction, reducing the clogging that might appear on high filtration materials and avoiding the concentration of fines in one point. Also its B3 paper’s porosity allows clarity of flavor, and the rigidity of its structure minimize the contact points with the dripper creating even balanced cups.

The new B3 Technology has been developed together with Matt Winton (2021 World Brewers Cup Champion) during a whole year prototyping and testing.

    B3 HYBRID filters are packaged in a flat stack with pre-folded creases for users to fold.


    1. Fold the 2 pre bend marks of the filter following the indentation marks on the paper. It is not necessary to keep the flat bottom shape of the filter; you just need to go over the folds.
    2. Push down the bottom circular area of the filter
    3. Place the filter in the dripper.
    4. Rinse the filter, starting from the center and moving towards the outer edge by pouring hot water in a circular motion. Make sure that the entire surface of the filter is stuck to the walls of the dripper, without leaving any air channels between the filter and the filter holder.

    The B3 HYBRID shape is a Sibarist new filter design in combination with the B3 technology.

    A Matt Winton Collaboration “Collaborate to create!”

    The B3 Specialty Coffee filter technology developed together with Matt Winton (2021 World Brewers Cup Champion). Matt has been our guideline during the whole development process for more than a year, he has been testing all our trial materials providing his expertise and feedback during the whole process, letting us to rethink the composition and processes,

    It has been a long journey but thanks to Matt’s expertise, his willing to experiment and to find the perfect material, we have finally obtained a very unique and extraordinary material that can be applied with different filter shapes, The B3.

    The B3 HYBRID, Matt Winton.

     “My favourite thing about this new paper and shape is that it’s unique, and has all the things I love in brewing with a cone brewer, but improved. The rigidity of the paper sits off the ribs of the brewer, creating more flow through the dripper, and even though you have to fold manually. We get an even flow through the bottom of our dripper, instead of that last gram or so of coffee being under extracted as there’s less flow through the bottom of the dripper.

    The paper itself flows really well and fast, and just slows down a little bit at pour 4 or 5 towards the end of the brew - but I haven’t experienced any significant clogging, unlike some other paper filter when I use light roast, high density coffees.

    The taste profile I get is something really clean and sweet, and there’s a richness that comes from a more even extraction. The first time I used it, I had to alter my grind setting and the way I brewed slightly to make it extract similarly to normal cone brews, but I’ve always preferred brews made with the B3 Hybrid Cone paper over regular cone paper brews - even compared to what I used to consider the best brewing I could get from cone drippers.”

    About the B3 technology, Matt Winton.

    “I’ve always been obsessed about narrowing down variables in coffee brewing, where I would lock all other variables, and focus on just one thing until I found the best. It wasn’t until I started exploring the role of the paper filter in pour over brews, that I saw it’s a huge factor!

    I found it difficult to get a paper that drew down quickly, but also had the clarity of flavor I wanted. So together with Joaquim and Lambert we sourced a whole new paper material that hadn’t been used for brewing coffee before, and tweaked it to become what I believe is the best brewing paper available. Every parameter was tested; porosity, tensile strength, thickness, sealing, and shape, in order to come up with this final paper - it was a project we’d worked on for over 12 months.

    The result is a paper that flows very quickly, but more importantly, very evenly, and is a thickness that stands off the walls of the dripper, to reduce clogging, and maximise the potential of each brewer. With the B3 paper you can maximise the potential of your dripper through a more even extraction. A rigid, thicker paper encourages flow, but creates a clear, clean, sweet cup profile.


    The B3 FAST Specialty Coffee Filters are entirely produced locally in Barcelona.
