As a beginner, it is good that we have some advance information about roaster. First, you have to identify the area you are going to roast. If you like dark roaster, a lot of smoke is produced. However, electrical home roasters have some filter to catch the chaff that causes smoke. Planning to roast a lot, it is good if you have access outdoors. The problem is if you are living in an extreme hot or cold area. Next, be ready also for the noise of the roaster. If you don’t want noise, better look for a roaster that can somewhat minimize noise while roasting. However, if you can bear noise then no problem.
Home coffee roaster has life expectancy. Don’t believe on advertisement that roaster will stay longer. If it is stated that there is two years warranty, then be ready to replace the roaster after two years. Better choose cheap roaster to have great savings in replacing it for a new one.
