A brewery is two businesses sharing a building: a production operation measured in barrels and a taproom measured in pints, and the connective tissue between them is usually a spreadsheet maintained by whoever was least busy. The beer that leaves the bright tanks and never becomes a sold pint has a dozen honest explanations and one honest cost, and without reconciliation the brewery pays for all of them.
1. The un-reconciled pour. Every keg moved to the taproom should become a countable number of pints. Without systematic keg-to-POS reconciliation, sampling, staff pours, foam loss, and the occasional honest theft all wear the same costume: "shrinkage."
2. Production blind spots. Batch costing done monthly from invoices tells you what beer cost last month. Real-time batch costing per barrel — water, grain, hops, labor, packaging — tells you which SKUs actually earn taproom margin and which are vanity projects with fans.
3. The growth guess. Which beers to scale, which to retire, and what to brew next Tuesday are decisions made on anecdote because the per-SKU, per-channel margin picture doesn't exist in one place.
A reconciliation layer that matches bright-tank output to keg movement to POS pours weekly, flags variance per tap and per keg, and computes pour-cost per SKU in real time. Batch costing updates as ingredients are consumed, not as invoices arrive. The weekly report reads like a P&L the brewer actually wants: per-beer, per-tap, no anecdotes. Two weeks to install on systems the brewery already runs.
A taproom selling 4,000 pints a month at 22% average pour cost that trims three points of shrinkage keeps roughly $1,400 monthly it was already brewing, kegging, chilling, and losing — $17,000 a year of found margin. The per-SKU margin picture then pays again by killing the bottom-quartile beers nobody orders twice.
Ask how many pints the last keg of the flagship actually produced, versus what theory says it should have. Every brewer has a number in their head; almost none have it from data. The distance between the two is the taproom's real margin.
