Re: What is the normal size of your corretto roast
I used to do smaller batches until I got my confidence up, I didnt want to destroy too many beans learning the ropes, luckily Ive only had 2 batches early days that were totally unpalatable and went into the bin.

What is the normal size of your corretto roast?

Re: What is the normal size of your corretto roast
Same here or sometimes 600g to finish with 2 x 250g batches.Originally posted by The Goodies link=1193118754/15#20 date=1195554837I always average around 300g as once reduced it is about 250g so it fits into a 250g coffee zip bag with value ready for degassing.
I then print a label on it so I remember what is in the bag.

Re: What is the normal size of your corretto roast
Since posting 400g as my roast size I have tried a few at 500g and the last one at 600g and they have all come out nice and even, Ive done a few blends and they have come up a treat as well.....the joys of Corretto roasting!!!!

Re: What is the normal size of your corretto roast
I normally roast 500g at a time because
(1) That gives me 5 roasts per 2.5kg bag that I get from beanbay,
(2) that many beans just about fills my bean cooler device I made,
(3) 2 roasts at 500g and I have enough coffee for a couple of weeks.
Now I do roasts for a couple of friends so I have been roasting a bit more lately.

Re: What is the normal size of your corretto roast
I was just thinking the other day about this very topic! I have a decent sized Breville "Bakers Oven" (Squareish tin).
My usual roast at the moment is about the 600g size... BUT just then I tried a 840g roast (this gives me exactly 700g roasted.. 500g bag + 200g bag... or 3 roasts gives 2kg ish
I think this size was pushing it a bit for the BM and the HG i have. (Time for an upgrade!!)
My problem before was my cooling machine... it couldnt really fit more than about 400g of roasted beans. NOW I have a monster that i constructed tonight! I made it out of a piece of ducting/woodheater flue, sealed one end, installed a sieve in the middle of the tube and a handle on the side, cut a tidy whole in the bottom for vacuum hose and fashioned a lid with a hole in to let the air through and create a well in the beans. Works a treat! Cooled v quickly and i could probably do 1kg++ really easily.
Ill stick some piccies up on here once i take a couple!
But back to the topic - 840g in my machine didnt seem to have the beans moving around as much... especially once they grew in size a bit. I was stirring it a little to be sure (didnt want to waste that much!). seemed to go into 1st crack at an earlier temp than usual for fc and sc. Still a nice even roast though - and it never threatened to spill over the side!

Re: What is the normal size of your corretto roast
My minimum is about 320gms and I do up to about 400gms.
I know I could happily do much more but I dont need that much.

Re: What is the normal size of your corretto roast
I normally roast 400 grams also.... but have done as much as 700 grams and as little as 250 grams (but that was a "one off")...
I also find that larger batches are perfectly even.... and with the rate I go through coffee (I was going to say "burn through" but that has other connotations
) it is just as well.

Re: What is the normal size of your corretto roast
i agree with HB... the bigger batches were oftern more easy to control....

Re: What is the normal size of your corretto roast
"does anyone find that with larger batch sizes they get a more uneven roast?"
No, not so far anyway. I did 400g tonight, cf the usual 300g, and found
the result if anything more even, and certainly easier to control.
I think 400g will become the "normal" batch size. This is because of my
wife. She (a) drinks too much coffee; (b) steals it to take to work; and
(c) finds people to give it away to. For example, I did 2x300g on Tuesday
and Wednesday, now down to about 100g in each bag and I havent even
tried it yet

Re: What is the normal size of your corretto roast
Ive got a 1kg Breville and with 150-250g in hopper they fly all over the place and out of the roaster. With 300-400g this does not occurr, plus the larger batches last a little longer as well.

Re: What is the normal size of your corretto roast
thanks guys, ill try a larger batch size with something like the huehue which I know gives a nice even roast. And hopefully it will give me more control aswell because at the moment by the time I hit first crack and try to slow things down a bit its a case of too little too late as second crack is well on its way.
ill give it a go next time Im roasting.
Thanks again

Re: What is the normal size of your corretto roast
Rollo,
Agree with Mal, I found that smaller batch sizes [<250g] tended to be a little uneven and harder to control between 1st & 2ndC.
Im getting good results with 400 & 500g, one day Ill try more just to see how it goes.
I got great improvements in my roasts by making sure the tip of the heat gun was just inside [a couple of mm] the bin and dropping the HG temp down to about 520C.
Earlier roasts @ 600+C with the HG tip above the bin were uneven and harder to control.
I put this down to creating a more constant temp within the bin.
Funnily enough I also reckon the 400/500g bean size is better distributed by the paddle than for smaller masses, the weight/momentum of the beans seems to ensure a better mix.

Re: What is the normal size of your corretto roast
300g is my general batch size and Ill do several of those each time I roast. If I know that I cant roast for a few weeks then Ill up it to 400g or 500g. Or if I just want a bit of robusta or monsooned to play with, then Ill do 150g or 200g.

Re: What is the normal size of your corretto roast
Gday Rollo,
It could have been the bean variety you were using or maybe the heatgun is a little small for the job. In my case, Id reckon that the larger the batch sizes the more even the roast is once you get above 200-300g batches. Ive noticed with smaller batches than this in the Big Loaf that the roasts can start to get a bit patchy so I avoid them these days....
Cheers mate,
Mal.
