Since I have seen so many members here talking about freshness of the roasted beans, how about doing home roasting?
Wondering anyone here has ventured into roasting green beans? Like using Gene Cafe roaster or other brand? Or even using a pop corn maker to roast like I saw on YouTube. Btw, where to buy green beans?
Wow, lots of interested roasters. Good to see the direction that Malaysians are heading to in specialty coffee
I'm actually a home roaster that started with a popcorn popper, moved to a Gene Cafe and now have a proper commercial drum roaster on the way. Overall I've been roasting for almost 2 years now.
I have a thread here on Lowyat offering roast on demand beans to help sustain my hobby/learning/potential career change
. Don't want to pollute this thread with sales, PM me separately if you're interested or questions
Anyways, Gene Cafe is a decent home roaster to start with but the main heartburn is the lack of thermal logging to allow you to properly profile your roasts. This influences consistency and makes it more trial/error to recover a bad roast (underdevelopment, overroasting). However, it's not too costly as a start on your journey to learn about real coffee roasting
As for green beans, there's no actual way around things. AP is the ugly monster that continues to want to block your way. Without one, I mostly get from eBay and also SweetMarias when friends or family travel but it's not getting very economical now with the USD rate as well as the measly quantities you can bring in (too much and customs is going to get alerted)

Finally! Someone interested in the same thing, and asking the same question!
I've been interested in trying out some home roasting as well; not quite using a popcorn maker but to use one of those halogen turbo ovens sitting on a simple motorised stirrer.
But the big problem seems to be getting the green beans! It seems such raw coffee beans can only be imported into Malaysia with an AP (another crony enriching mechanism) so getting them direct from Sweet Maria's is out. I have found a couple of importers but they all do only wholesale... so unless I commit to at least many kilos of beans they are not interested.
I have raised this topic on this forum before, with zero responses. Perhaps we can raise some interest and if we find a few more like-minded individuals we can buy a sack of beams to experiment....
If you have found a local importer willing to sell in bulk I don't mind sharing
Halogen turbo ovens may work well but make sure you can hit 250C and you might want to figure out how much thermal energy is available - that influences what is the quantity you can roast per batch

How do you guys plan to roast the beans? I know of heating them until they caramelize till they pop in the frying pan but this will cause inconsistent color.
Btw, i just got my Brazilian coffee and im loving it!
The pan method is pure conduction heat. In this case, lots of agitation is require to make sure there's no burnt spots. Also, you may risk hitting first crack fast and the outer layer roasting too quickly compared to the inside. This can cause very bad under-development and gives you a grassy/herby taste to your roast. Development is very important for sweetness especially for espressos
