I’m roasting beans today and have just finished my first batch. I’m experimenting with single origin blends combining a few different roasting profiles. These are the lightest roast I will do, the next batch will be a darker roast, with a half quantity of an even darker roast. In theory this will give a more complex flavour profile.
I am still quite new to roasting and I am trying out different things to see what I like. I generally do plunger coffee not espresso, and find I prefer lighter roasts in general. Small changes in how you roast can make big differences in the outcome though - I have been focussing on cooling the beans quickly after roasting which made a noticable improvement in flavour.
I didn’t get the third batch as dark as I intended, in the end it was much the same as the second batch. Looks pretty good though, and the different speed of roasting should have developed a few different flavours even if the last two batches look the same.
