    Does the FREEZER keep beans fresh for longer ?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    How many people have told me this over the years

    Be it instant, ground or whole roasted beans

    Can some of our more informed members/sponsors fill me in on the validity of the Freezer theory

    If it is true - any idea how much longer before the beans start to degrade, and should they be left to develop in or out of the freezer (for the usual 24-48 hrs)

    thanks

    Re: Does the FREEZER keep beans fresh for longer ?

    There is an interesting discussion about it here.

    Jim from coffeecuppers.com had this to say:

    The basic answer is

    1. freezing retards staling, and very deep freezing (-40 C or F) eliminates it. Coffee in a home freezer stays fresh for at least a month.

    2. it has to be done right, or its useless. The coffee has to be stored airtight and allowed to warmup completely before reopening the package. Otherwise one gets condensation, which is worse than staling. It is best if as little moisture laden air as possible is stored with the coffee, vacuum pack is best, wrapping tightly or storing in a filled to the stuffing point jar also work well. I use freezer or valve bags which I roll up tightly to expel the air, then seal. This works fairly well, and keeps the coffee fragrant for at least three weeks.
    Additionally, one of the posters to that thread thought that freezing a very short amount of time after roasting helped.

    I havent really had time to try it out. I dont think that I have ever had enough coffee around for it to be worth trying ... especially with the new machine. I went through 250g just yesterday and today :o (No, relax; I had lots of people over!)

    Interestingly, George Howell of Terroir Select Coffees in the US of A is now deep freezing greens. I believe that Howell is the man that convinced Daterra to invest in the Penta packaging system for their coffees ... basically if you buy a 24kg box of daterra sweet collection it has two 12kg sealed foil bags of green beans inside it! It would be interesting to buy some green, deep freeze some and keep some normally, then roast them and cup them head-to-head in a year.

    Cheers,

    Luca

    I dont know about roasted coffee, but George Howell explains (http://<font color="#ff3300">http://...144/28/</font>) why deep-freezing green beans is best for maintaining their freshness and quality.

    Sorry, but when he said vacuum packing roasted beans is best he lost a lot of credibility with me.

    Using a standard FoodSaver I performed several experiments vacuum sealing roasted beans after detecting a very noticeable decrease in the flavor of some beans Id vacuum packed. In every case with every bean I tried whether sealed immediately after roasting cooldown or up too 24 hours later and whether opened as little as an hour after being packed or up too a week later the result was the same. A very noticeable decrease in the flavor in the cup.

    The results were absolutely clear with no ambiguity in them at all. If I wanted the complete and full flavor of the beans vacuum packing was out of the question.

    If you are willing to sacrifice that top layer of taste then go ahead and vacuum pack. It will extend the shelf life of the beans. But it will do it at the cost of loosing all the wonderful nuances that truely make the high end beans stand out.

    The first coffee I intentionally did this with was some wonderful Columbian Mesa de los Santos. When I unsealed the first test bag and stuck my nose in it to take a whiff do you know what the very first thing the smell triggered/I thought of was? Folgers! :P :P :P Need I say more?

    Yeah I can see deep freezing lightly vacuum packed greens working. Realize however that home fridge/freezer units are not deep freezes. These units also stay frostless by regularly warming up enough to melt any frost that has accumulated, as well as the top layer of any food in them. Not a good thing if youre looking to retain maximum flavors.

    I have a very old freezer that doesnt defrost so would probably be good for testing some of this (but I wont).

    Where he lost me was where he said valved bags would keep roasted coffee for "at least 60 days without appreciable degradation".

    He hadnt even started talking about freezing green beans at that point.

    Youd probably want to use a blast chiller to freeze the beans.

    As for thawing them out without any condensation, thats another story. Maybe a hairdryer to evaporate any condensation that occurs.

    Unless you plan on saving your greens for 5-10 years, theres no reason why youd possibly want to freeze them.
