    Why is the trier important during roasting?

    The trier gives you real-time access to what's happening inside the drum. By sampling beans during a roast, you can assess colour changes, smell aroma development, and make small adjustments with more confidence - whether that’s to your heat setting, fan speed, or end temperature. It’s especially helpful for catching underdevelopment, tipping, scorching, or other defects before the roast ends.

    What comes with this replacement trier assembly?

    Everything you need to fully replace the original trier: a wooden handle for safe, heat-resistant grip, a stainless steel spoon head for scooping the beans, and the screw that joins the two together. If your original has been lost, damaged, or worn down, this assembly brings your setup back to full function.

    Is it compatible with all Aillio Bullet models?

    Yes – this trier fits the R1, R1 V2, R2, and R2 Pro models. It installs into the existing trier slot and requires no modification or additional tools.

      Berigora (coffeesnobs)

      As a R1 V2 owner with 400 (350g roasts) under the belt, I am envious of the new functionality of the R2; larger capacity, more energy efficient, easier to clean and maintain and stirrer in the drop tray.

      I've had my Bullet v2 since December of 2020, back when stock was limited and I had to pounce on the buy button when they became available. Now, after all that time, I wouldn't hesitate to buy it again tomorrow if I had to

      I believe it the best 1KG roaster you can buy.

    Frequent Questions

    Is this the same trier that originally came with my Bullet?

    Yes – this is a like-for-like replacement. It matches the original part that ships with all R1 and R2 models.

    How do I know when to replace it?

    If the spoon is dented, the handle has come loose, or the trier isn’t seating properly when rotated, it’s probably time for a new one. A well-fitting trier helps ensure safety, accuracy, and ease of use.

    Can I swap it out myself?

    Definitely. Replacing the trier is simple - just unscrew the old one and attach the new assembly. No special tools needed

    Will it feel the same as the original?

    Yes – the wooden handle is designed for the same comfortable grip, and the spoon shape matches what you’re used to. You’ll be back to checking your roasts in no time.
