    Roasting in a Corretto..

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have done a couple of roasts in a corretto after firstly using a popcorn maker and i have produced some ok and some bad roasts. Which leads me on to a few questions. At present i am only going of the temp of the heat gun as i dont have a thermocouple and data logger as yet.

    My question(s) are...

    Are you looking to get the temp up to as hot as possible and first crack to happen as quick as you can then turn it down and wait for second crackI guess i am looking for someone to give me a bit of a guide on temperature through roasting... I have looked a lot through the forum but there is so much info to flick through.
    Also what is the reason for leaving the beans after roasting for 24-48 hours?

    Cheers

    Chris :)

    First crack should happen at around the 10 minute mark/200 degrees C.

    There is a spreadsheet in one of the stickys that is a good guide for roasting.... But without a temperature reading it is useless. Buy a multimeter with a probe ASAP and youll get much better and more consistent results. You dont necessarily need one that has a data port, just pair it with a stopwatch and the guide and youll get the same effect.

    As far as leaving the roast for 48 hours, this is to degas the beans and develop flavour. Some beans need a week or more to develop their full flavour potential. Good luck with your roasting.

    I did heaps of successful roasts with the corretto before I got the data logger. As Daniel says above, first crack should be about 10 to 15 minutes. Once I got first crack, I raised the gun 2-3 cm to reduce the heat, and usually got second crack in another 5 mins or so.

    As soon as I got second crack I dump the beans and cool them as quickly as possible.

    Having said all that, I have done roasts where the times were out of this range and the beans still tasted great.

    The data logger lets you see if things are going a bit out of whack, otherwise you can not really tell.

    If you brew the same beans everyday from roasting them, you will taste the flavour changes as they age and develop.

    Cheers

    Thanks very much for both of you for your information. I did another roast after i wrote this thread and tried it on a higher heat and a quicker crack for first crack and it all ended at 12 mins. That was about 11am yesterday. I tried the beans today cause i couldnt wait. They seemed pretty good to me, the smell when i opened the bag was amazing but i guessing thats only half of it

    I will keep trying, i have order some more beans, and will apply what both of you have said and see what results i get

    thank you and have a nice New year :)

    Chris :)
