Carbs, especially when eaten in large quantities, causes a large spike in ...

The digestive problems you've experienced may be due to the acidity of the coffee. Now lighter roasted coffee will definitely be more acidic so the roast level of the bean can be at play. Not only that, but underextraction can cause high levels of acidity also. The only discernible difference I can garner from what you've told me is that in the Aeropress ...
