to tease @keithnator3000 and the #coffeelover/#coffeelovers, here are my two last batches of #coffee #roast. at top a sumatra at city+ and full city+. at bottow south american geisha, wet process raw and city.
tried out of the roast the sumatra as espresso at full city+. a surprising residual acidity at this roast level which gives a perfect balance. intense, notes of preztel mixed with mild earthy tones alongside cocoa. will certainly develop further complexity after a proper rest. less sugar than expected but the raw batch is something like 2yo. will try at city/city+ next time.
didn't try the geisha yet, I will with my breakfast as pour-over during the week-end 🤩
@certainlytwice Is there a YT channel that goes over some of this so I can follow along?
@keithnator3000 I did learn by experimenting on my own. so unfortunately I am not aware of any nice YT channel dedicated to roasting. but my tecujuhnique is very simple : pour the green beans over any pan with high sides, stir continuously and cook until it gets roasted at the desired intensity 😁 at first try with a heating power at 50-66 % for a heating source of 20 cm width. if the color doesn't change at all after 10 min, increase the power.
a typical roasting time would be 13-18 min. during the process there are 3 important changes : (1) the color for sure (2) the scent / smell, from fresh peas to toasted bread, with pine tree sometimes (3) the sound !
during the process two crack sounds occur from the beans, the first is loud like when cracking a small wood branch ; this crack when complete marks the city level (minimum normally accepted roast level, shorter times might damage your bean grinder afterward). the second crack is more subtle, like frying noises and you can see some oil coming out of the beans, they look a bit greasy. the second crack when complete marks the full city level. you can push more (italian, then french roast level - basically charcoal) at the risk of increased bitterness.
you can start with a cheap little bag of random green coffee. even if it is your first batch, you'll enjoy it more than any other commercial coffee 🥳
@certainlytwice Going to practice so I can treat myself with a fresh hot roast this winter
@keithnator3000 I did learn the technical terms a posteriori from random internet readings, eg. wikipedia. if you find any interesting information channel, please feel free to share 😁
