Excellent! My kettle has a digital temp setting, so I'll give that a try tomorrow morning.
I have no idea what the roasting process is for flavored coffee beans. I suspect that they are tossed in flavored oil after the roasting process. What I do know is the effect of hazelnuts on my system. It's not an "I need an epi-pen" kind of reaction, but it's unmistakeable. I usually get it from coffee, once even just by sitting next to someone in a faculty meeting who was drinking a hazelnut flavored roast. Oddly, it's not a smell I can instantly recognize (like my other allergen, shrimp); I only know it from its effects.
As far as the grinder, I'm going to do a more scientific experiment and get some of my favorite commercial blends in whole bean form and compare them to the pre-ground versions I have been buying. That way, I'll be comparing apples to apples.
The flavoring process is similar to what you describe, but that is not a flavored coffee. That is a single origin coffee. No one added hazelnut flavoring to it.
Tasting notes are just what a person writes down as they 'cup' the coffee. Tasting notes are subjective, not absolute. Just like listening to music. You'll hear a song and describe what you hear, the guy or gal next to you will describe what they hear. Some things will be in common, some will be unique.
For instance, a friend of mine owns this roastery and also roasts that same coffee: [Invalid or Expired Link Removed]
His tasting notes are similar and yet different.
But your allergic reaction is a real thing, and I am not attempting to minimize it or discredit what happened. I just wanted to clarify that no one added hazelnuts to that coffee or hazelnut oil. If this roaster had done so, it would have been labeled as such clearly.
As for doing the comparison, great idea. Be careful to make sure roast dates are close between the different beans.
