    Coffee Freshness


    Does the fact that the coffee bean appearance has an oily texture indicate its freshness or is that not necessarily the case ? I have purchased a batch of Kenya AA ( 3 weeks old ) and I have had problems with crema, bitterness and a somewhat almost filtered tasting coffee. To the point were I raised equipment issues on this forum to see were I could be going wrong. I bought a better grinder and tested it out with a batch of Yirgacheffe that I had just purchased and the grinder has made an exceptional overall improvement. My coffee making success rate significantly imporved with the new grinder. Today however I switched to the Kenya AA and had some terrible cups. I wonder whether to question the freshness of the beans or perhaps it maybe that the grinder needs a different adjustment for this particular bean. Hence I am curious whether the oily texture is a sign of freshness. Many Thanks

    It kind of depends on how oily.

    Generally speaking, if a bean is noticeably oily very soon after roasting, it means it has been roasted to a darker level. If there is a LOT of oil early on, then it is probably too dark for most coffee to still taste good.

    A lighter roast will often have some oil start to appear as the days pass after roasting. This is normal.

    3 weeks old is probably past it for the Kenya AA anyhow.

    A lot of oil = very dark roast and/or quite old.

      Thanks for your response. I have learnt something new regarding the Kenya AA. Just ordered an IRoast from evil bay today after blowing two popper within a forthnight at least freshness wont be an issue when that arrives.

        Carloz, Stick your nose in the bag and have a good sniff ,if the beans smell rancid then they are stale.If they smell like they have just been just roasted then they are probably ok.
        Some roasters tend to roast very dark causing the nearly all the oils to come out of the beans. Most of the oil should be in the bean.
        If you order some roasted beans from beanbay have a good look at the bean smell them crunch them, you will get to know fresh coffee when you see it and smell it.

          Thanks for the info. Ive purchased from this roaster for about 1 1/2 years and hes always been consistent. Ive always ordered Kenya AA or Kenys Dorma and they have been always on the oily side. I may have scored a bad batch from him with this particular one because the Yirgacheffe which came with this batch is perfect. Its all a learning curve and much appreciated thanks.

            Why not discuss it with the roaster?
