11 Time-Tested Secrets to Authentic South Indian Filter Coffee

11. Troubleshoot and Store Equipment Properly

Common problems are fixable. Weak decoction usually means coarse grind, too-fast drip, under-packed coffee, or short extraction time—use a slightly finer grind, check packing pressure, and let the drip run a bit longer. Bitter or burnt flavors point to overheated water, too-fine grind, or burnt beans—lower your water temperature and adjust grind coarseness. Slow or blocked dripping often means the filter holes are clogged; clean with a soft brush or soak the perforated plate in warm soapy water and rinse thoroughly. Store beans and chicory in opaque, airtight containers at room temperature away from sunlight. Replace rubber gaskets or worn discs on long-used filters; cheap filters can develop pinhole clogs over time. Regular cleaning and thoughtful storage keep the flavor consistent so your next cup tastes like the one you wanted.
