Brian Smith of Lincolnton, North Carolina has maintained a sourdough starter for more than five years. He named the starter Clyde, after his grandfather Houser, who went by Clyde as a nickname his entire adult life. The name felt right. His grandfather was steady, reliable, and required consistent attention to keep in good shape — qualities that also describe a sourdough starter, if you are being honest about what the work involves.
Clyde has nearly died twice. Both times were Smith’s fault. He will tell you this without prompting.
The First Near-Death
The first time was about four months in. Smith went on a work trip — a multi-day conference for school district administrators — and left Clyde in the refrigerator with what he thought was enough flour to last. He had read that refrigerated starters could go a week or more without feeding. This is true, but he left Clyde for ten days, and when he came back the jar was covered in a grey liquid and smelled wrong in a way that was hard to describe except to say that it did not smell like bread.
He almost threw it out. He poured off the grey liquid — which is called hooch, and is a sign of a very hungry, not necessarily dead, starter — and looked at what was underneath. There was still some active culture in there. He fed it. It barely responded. He fed it again the next day. By the third feeding it had started to bubble again. By the fifth day it was rising predictably. Clyde had survived.
Smith made a note in his notebook: “Starter recovery — 5 days from near-dead to active. Do not leave longer than 7 days unfed in fridge.”
The Second Near-Death
The second incident was more dramatic. About a year and a half into keeping Clyde, Smith left a jar on the counter after feeding it and forgot that a family member — visiting for Thanksgiving — had cleaned the kitchen while he was out and had wiped down every surface, including the counter, with a disinfectant spray. The spray had gotten into the open starter jar. Not a lot of it. But enough.
The starter did not respond normally to the next feeding. It smelled off — not the sharp, pleasant tang of healthy fermentation, but something chemical underneath it. He fed it twice and neither feeding produced normal activity. He transferred a small amount to a clean jar, discarded the rest, and began a careful recovery — feeding twice daily with unbleached flour, warm water, and no contamination from the spray bottle that was still sitting on the counter.
It took about eight days to return to full activity. He moved the disinfectant spray under the sink. He now keeps Clyde in a jar with a loose-fitting lid that he is careful to keep away from cleaning products.
What Five Years Looks Like
Clyde is now a mature starter — meaning the culture is stable and predictable in a way that a young starter is not. New starters, in the first weeks after creation, are inconsistent. They may rise dramatically one day and barely respond the next. They are establishing a microbial balance that takes time to settle.
A mature starter, one that has been maintained and fed regularly for years, is more stable. Smith can predict, within a window of about an hour, when Clyde will peak after feeding at a given temperature. That predictability is what makes consistent bread possible. The starter is not the only variable in sourdough baking, but it is one of the few you can control with precision once you know it well enough.
He keeps a backup portion of Clyde in the freezer. He learned this after the second near-death. A frozen backup is not ideal for ongoing baking, but it is insurance — dried or frozen sourdough cultures can be revived. If something happened to the jar on the counter, he would not be starting over from scratch. He would be starting over from two years ago, which is still better than nothing.
Clyde’s health directly affects every bake — including how Smith reads fermentation timing and what he records in his baking notebook. More at About Brian Smith Lincolnton.
