Brew and beans matter more than people expect. Paper filters remove more oils than unfiltered methods and are often kinder on reflux. Cold brew diluted with water or milk can feel rounder and less acidic. On sensitive days, a smaller mug you sip slowly may feel far better than a large, fast latte. And bean choice is your quiet superpower: low-acid decaf or balanced medium roasts hold onto the aroma and comfort while trimming the “edges” that can aggravate stomach and sleep.
