Hello, first of all, don't mess with grain by grain. It's my favorite brand at the moment.
I even have to buy it in Caracas because I can't find it anywhere else.
Second, I loved that way of roasting coffee, adding flavors, although I personally wouldn't add brown sugar because it alters the roasting a lot.
And finally, I recommend that you grind little by little so you retain more of the aroma.
Bean by bean, it's wonderful! If the first time we roasted it, it lasted a long time, and a tablespoon goes a long way when brewing coffee, I think the bean is more robust; it's a gourmet coffee. Whenever I see it again, I'll buy it in that same form because I loved it so much.
As for the brown sugar, it's an extra touch. What I've learned is that I should add less. I've spoken with someone with more experience, and they told me they add star anise. I even read that some people grind it with cardamom, which gives the drinker a sensory experience with that subtle touch.
We are making wholesale purchases of grain by grain because in Caracas we only saw it available in two markets.
How nice! Where do you buy it? I bought it at the 2024 coffee event, and it went a long way. Imagine if I bought more, that would be wonderful!
