Sanitation Is a Flavor Variable
Line cleaning and keg handling are not compliance chores. They directly change taste.
If your draft cocktail tastes different by day four, your first question should be sanitation, not citrus.
Residue in lines and couplers changes aroma, perceived bitterness, and finish long before guests can tell you what is wrong.
Operators often treat cleaning cadence as a back-of-house checkbox. In reality, it is a primary flavor control variable.
Draft programs should carry a line-clean timestamp the same way prep kitchens track date labels. If you cannot state last clean date in seconds, your control loop is weak.
Shelf-life risk is also a chemistry issue. Acid-forward and fresh-juice builds degrade differently than spirit-forward, clarified, or shelf-stable specs.
That is why Draft mode separates flavor targets from operations guardrails. A recipe can read perfectly on ABV/Brix/acid and still fail in service if system hygiene is drifting.
Build SOP reminders into shift handoff: line-clean interval, purge confirmation, and keg age checks. Do not rely on memory during rush.
The goal is not only safety. The goal is repeatable taste at scale.
Great draft programs are boring on purpose: stable, documented, and clean.
