Additional Information

On this course we will use our Ikawa sample roaster to roast the same coffee to different levels so we can see the dramatic effect the roast plays in developing coffees unique character. We will also show you our Giesen roaster which might even be running on a production roast day! 

Coffee arrives at Hot Numbers in green bean form in 60kg sacks as a hard seed with a grassy smell, not really representative of coffee as we know it! We roast each batch in our 15kg Giesen traditional drum roaster, carefully controlling the gas flame over time until we find a recipe where the coffee tastes the best we feel it can be. We save this recipe as a profile so we replicate similar batches again and again for consistency. Each varietal of coffee may use a different profile to bring something different from the bean and this is where the skill lies between art and science. We may each consider a different roast level to be preferable from a medium to dark roast and that’s what leads to understanding and conversation which we always encourage.
