BIT Double Filter Basket – 21 grams

BoB and Renato are a breakthrough in basket design, featuring the first true round-bottom shape in over 60 years. Unlike flat-bottom baskets that encourage channelling and edge-heavy flow, these are engineered to guide water toward the centre, delivering smoother, more even extractions.

The result? Greater flavour clarity, balanced sweetness, reduced bitterness, and longer extractions without over-extraction.

Taste the Difference:

Start with your original basket. Pull a shot, record the dose, yield, and time. Taste it, and save some for later.
Swap to BoB. Keep parameters the same. Pull another shot and compare.
Try Renato. Repeat the process.
Compare all three. Taste side by side (hot and cool) to notice how BoB and Renato enhance body, balance, and complexity.
