After the roasting process is done, then what?
dekafka
Hello peeps,
I have been looking extensively on the forum, and I've seen lots of mentions of something called gassing, and bags with valves, mason jars etc... but I can't find a clear step by step of what to do after the roaster is off. Is there a "Post Roasting Basics" guide on this forum?

I have seen videos where they put the beans onto either a (cold) metal baking tray or a colander. Then I've heard that once it cools, it must get put into a sealed bag for a day or two before it's ready to grind. I have even seen some people storing their beans in the fridge after that. I had thought the fridge now regarded as a bad storage place because of possible condensation on the beans.

Anyhoo, it would be good to hear from those who know !
Thanks
Mark.

Firstly let me qualify that the following is my best understanding and others may not always agree.
After Roasting and Cooling the beans will continue to exude gas, mostly CO2 (and other lovely aromas). The gassing rate reduces dramatically after around 1-2 days. If in a sealed bag it can burst the bag hence the one way valves to allow gas out but prevent oxygen in.
Once roasted and cooled the beans can be brewed immediately but are at their peak about 1-2 days later and will then gradually deteriorate. This can be minimised by storing in a cool dark place (not the fridge or freezer) but the beans will be good for up to 30days (IMHO) if stored well and arent allowed to oxidise. (ie something like sealed/airtight)
The beans contain numerous volatile flavour/taste/aroma related (ie yummy !) oils/compounds which eventually escape leaving you with "stale" beans. Hence the huge difference between supermarket beans and freshly roasted
This process is vastly accelerated when the beans are ground due to huge increase in surface area
A rule of thumb (assuming stored in airtight, cool dark conditions)
Green beans 1-2 years
Roasted Beans 30 days
Ground Beans - minutes
I hope that is helpful

Thanks very much Phil, that is a very helpful summary of the important things. I guess I need to get some bags. Cool dark place is sorted (wife's subconscious) LOL.

Same experience as above, from day 3 the flavors start to degrade slowly.
I start drinking mine next day after roast.
Not keeping my beans sealed because I roast weekly, for the weekly consumption, thus no need for extra conservation methods.

I degass for 2 days most often. I read that too.
I store my green beans in 3L glass mason jars. (5lbs each)
I roast enough for 6-8 days of drinkin. woohoo
Oh. Put mason jars in cool dark place, builtin cabinet down low...
Remember beans absorb smell an moisture.
Plastic releases it's by product. Which is why you don't reheat in it.
People do anyway...

Thanks Renatoa, I will probably also roast weekly, not seal well, keep it in the grinder bean storage compartment...

Yep, must get some of those, plus the bags for the first 24+ degassing

I wonder if outdoors in the (dry, converted) garage is not too cold, temps below 0c often this year. Wouldn't that have the same negative effect as a freezer, ie, possible condensation & oxygenation?

But is it bad for the beans to be that cold?

If you plan to roast under 15 C degrees, think again.

I can't comment for storage under zero, but the roast will fail.

Hi Renatoa,
I am not sure I will need to be roasting outside the house, depends on just how messy the Dieckermann is... but I was thinking that because it is blasting very hot air at the drum from close up, it won't matter, it would be much stronger than the impact of cold surrounding air... so from your experience, the cold air would prevent a proper roast?

After the roasting process, Fresh-roasted coffee needs to "rest"!

Over the next few hours and even weeks, the coffee will ripen into its optimal taste profile and lose the negative combustion tastes. This is tricky to make general statements about. It is true that some coffees reach a delicious taste profile within minutes, but this is rare. Some reach an optimal taste within hours, but MOST coffees are best if rested for at least 1 day, and many are best resting for 3 days. Standard coffee shop procedure is to rest coffees between 1 and 3 days depending on the beans.

Hi Mark,

I also wait about 2 days after roasting before brewing. What I would suggest is brewing immediately after a roast, then brew 24 hrs after a roast, etc. keeping all other things the same, and see what flavor you like the best. Taste rules!!

As for containers, I like to use Evak Airless Canisters. Instead of including here an outrageously long URL, go to Amazon and search for "Prepara Evak Fresh Saver, Medium-Short Airless Canister". They will let the beans gas-out but will also keep air from coming in. Pretty much just like the bags except they are reusable and more durable. I use the 1.1 Qt size and really like them.
