After the old forum software breaking in a way that we were unable to fix, we've migrated the site to a new platform.

Some elements aren't working as we'd hoped - some avatars didn't survive the transition, and we're still having issues with attachments that weren't added as inline images, but we're hoping to have that all sorted out soon.

Early blonding in regards to extraction

Question from C-Man:

What are some of the reasons for early blonding in regards to extraction?

Thanks

    Re "early": Basically this is caused by using coffee that is "short" on oils. There can be a number of reasons incl using older (from the time of roasting) coffee, but it may also be due to equipment factors such as running it too hot and burning the grinds, OR it could just be that a certain origin of coffee is the way it is this year due to climactic or other environmental factors (its a crop, and it varies from season to season). It may also be due to mishandling by the operator (leaving beans stored in a hot or sunny position, poor handling, whatever. Also be aware that while many internet forum partiucipants will tell you to STOP the pour as soon as you see blonding, this may be a little too stern...... For example, if your coffee is destined to be a "milk", a bit of blonding wont be detected on the palate. And if you experiment with black coffee, you may also find that a bit of blonding is not going to destroy your coffee drinking experience and that you may be able to push through a little. Also, it may be that if the operator doesnt have the multitude of other variables controlled in the total coffee brewing process, that other resulting problems may have a far bigger affect on destroying your coffee, than a bit of blonding..... Also note that if you coffee was destined to be a "milk", and your coffee blonded early and you stopped it right bang on the point of blonding.....then you actually may not have a big enough espresso portion that will work with the milk, resulting in milk with a brown tinge...... Yes you can brew another and try to correct the early blonding (if you can), but if you cant, you wont have a suitable milk coffee period. "Early " blonding is a can of worms best left for individuals to experiment and decide upon, rather than something that is black and white. After that its up to the individual to try different things out and make up their own mind. Hope that helps.

    yes, thanks for a great reply! Sometimes I get early blonding and without changing anything I don't most times I think it is the roast or storage of the beans like you say.

    Or the humidity of the day - If I have a run of days with very similar temp/humidity conditions and the same beans I generally won't have to adjust the grinder. If there's a big temp/humidity swing, I might have to make fairly major changes to the grind.

    seems as the beans age, I need to grind a little finer to keep the color and creama and avoid the early blonding. just what I have discovered so far, also some roasts are better than others in keeping the hazel nut color even from professional roasters around here anyway.

    I've found that since I've had my VST I don't get much blonding, no idea why.

    Interesting... Me too.  I have plenty of blinding with the lever if I let it run but the Diadema and VST I'm always cutting off the shot with heaps of colour but the time has run its course.
