Sourdough Starter Storage and Dormancy
Refrigeration at 4 C slows metabolism roughly tenfold and preserves viability for weeks, while drying to flakes or freezing arrests it for months to years by removing water activity or halting diffusion. Cold storage progressively skews the culture toward acid-tolerant LAB, so revival is a re-selection, not merely a warm-up.
