  • Air flow problems

    hey fellow Coffee Snobs im having a problem with with some of my blends i seem to be getting a slight "bitterness"when im cupping my samples. my roasts are still dropping at around the same times(14 mins) but ive noticed my air flow is about 5-10 deg hotter than usual ,will this slight change affect my profile that badly?Any advice as im a self trained roaster and struggling to work this out :-/

    Sure could.

    If you didnt change anything else and have 10C air temp change... and assuming that the ambient temperature is similar then clean your flue/exhaust.

    Build-up on that side of the roaster will slow the exhausting air and add more heat thus changing the profile of the roast through the duration.
    (with a greater change at the end)
