A quick decision brief for this specific tool
Inputs that matter
One retained source-owned plan identity/revision/timestamp/scope and volume basis; explicit grain mass, mash-liquor ratio, target pre-boil volume, grain-retention rate, mash-tun unrecovered volume and sparge-delivery unrecovered volume with supported labeled units; exact plan-document provenance; optional complete observed pre-boil measurement tuple; reviewer, retention note and seven source/scope/process/unit/allowance/observation/decision boundaries
Output to expect
Canonical grain kg, ratio and retention L/kg, mash liquor, grain retained, mash-tun unrecovered, planned first runnings, required sparge delivery, sparge-delivery unrecovered, planned sparge liquor, total planned liquor, target pre-boil volume, optional signed observed minus target difference, six nondecisions, five named liter compatibility outputs and source-owned-mash-preboil-water-balance/v1 record
How it works
Normalize every explicit labeled input with NIST-published factors, reproduce the owner-documented mash liquor and retained/unrecovered streams, solve the separate-sparge balance against the retained target pre-boil volume, retain full precision and compare one complete observed measurement only as observed minus target
Every value must belong to one retained plan, grain bill, equipment revision, separate mash-plus-sparge method and source-stated volume basis; drafts, mixed scopes, BIAB/no-sparge/top-up methods, inferred units and Tool-default allowances are refused.
The result is not a recipe, mash-ratio, temperature, chemistry, pH, efficiency, stuck-mash, yield, process, quality, release, consumption, legal, health or safety decision; an optional observed residual is arithmetic only.
Choose your path
Built around the job you need to finish
Reconcile one retained source-owned separate mash-and-sparge water plan from explicit grain, ratio, target, retention and unrecovered-volume records, with an optional complete observed pre-boil comparison and no recipe, process, chemistry, efficiency, quality or safety recommendation.
Recipe-record reviewer reproducing a retained metric plan
Recalculate one approved water worksheet without hidden mash-ratio, retention or equipment-loss defaults.
Fix one plan/grain-bill/equipment revision and volume basis; transcribe kg, L/kg and liter inputs; inspect mash liquor, retained volume, first runnings, required sparge delivery, planned sparge and total liquor; export the v1 record.
Can trace every canonical balance value to the retained source while recipe, temperature, chemistry, efficiency and process choices remain with accountable owners.
Technical historian reconciling a labeled U.S.-customary plan
Normalize an older worksheet whose pounds, U.S. liquid quarts and U.S. gallons are explicitly labeled without collapsing its volume basis or inventing precision.
Use the supported avoirdupois and U.S.-liquid units, preserve source/revision/locator, optionally add one complete observed measurement record, and retain the signed observed-minus-target difference.
Gets the same canonical kg/L arithmetic as an equivalent metric record while the Tool never certifies the measurement or declares plan accuracy or process performance.
Auditor using a phone to reject incomplete water evidence
Exercise blank, mixed-scope, incomplete-observation and forbidden-decision paths without receiving brewing advice.
Load the de-identified example, clear required owners, test explicit zero losses, submit partial measurement tuples and every refusal boundary, modify a successful result, inspect page-session snapshots and clear them.
Can reject ambiguous records, recover at the owning field and retain a portable arithmetic record without mistaking simulated acceptance paths for brewing research, process approval or safety validation.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Keep one plan, grain bill, equipment revision and source-stated volume basis together. Normalize only explicit kilograms or avoirdupois pounds, liters or U.S. liquid quarts/gallons, and the two labeled ratio families using NIST-published factors.
Canonical value = Source value × published unit factor
Reproduce mash-side streams
Mash liquor comes from the source grain mass and source ratio. Grain retained and mash-tun unrecovered volumes are separate owner-documented inputs; neither is estimated or recommended by the Tool.
For a source-recorded separate sparge stage, required delivery is the target pre-boil volume minus planned first runnings. Add only the source-owned sparge-delivery unrecovered volume. A complete observation produces a signed observed-minus-target difference and no performance label.
A retained plan records 5 kg grain, 3 L/kg mash liquor, a 25 L target, 1 L/kg grain retention, 1 L mash-tun unrecovered and 1.5 L sparge-delivery unrecovered. The Tool reproduces 15 L mash liquor, 9 L first runnings, 17.5 L planned sparge and 32.5 L total planned liquor without endorsing any input.
An older retained record explicitly labels avoirdupois pounds, U.S. liquid qt/lb and U.S. liquid gallons. The Tool converts each value to the same kg/L balance while preserving the original value, unit, document revision and volume basis.
A draft mixes equipment revisions, omits the owner of a loss allowance, or provides only an observed volume without method, owner, identifier and timestamp. The Tool attaches errors to the owning fields and creates no exportable result.
Common Mistakes to Avoid
✕
Treating an online ratio or retention value as a built-in recommendation
✓
Leave numeric fields blank until the accountable plan supplies each value, unit and source. A successful calculation reproduces those inputs; it does not approve them.
✕
Mixing plan revisions or treating a target as an achieved measurement
✓
Keep one plan/grain-bill/equipment revision and volume basis together. Add an observation only as a complete, separately owned measurement tuple; otherwise choose no comparison.
FAQ
No. The ratio must already belong to the accountable source plan and carry an explicit L/kg or U.S. liquid qt/avoirdupois-lb label. Recipe and process owners select and approve it outside this Tool.
From the retained source record. Enter its stated value and unit; do not substitute a Tool default or an unrelated system's observation. The Tool multiplies it by canonical grain mass and makes no claim that the allowance will be achieved.
Not under this v1 contract. Its algebra requires source-recorded separate mash and sparge stages. Use the method owner and an appropriate reviewed workflow rather than forcing a different process into this balance.
It is only observed pre-boil volume minus the retained target, after unit normalization. A comparison requires the measurement value/unit, method or instrument, record owner, identifier and timestamp. The difference does not diagnose losses or grade performance.
Only to identify the published conversion factors for supported labeled units. NIST does not validate the plan, ratio, retention rate, loss allowance, volume basis, measurement, brewing process or product decision.
About Source-Owned Mash Water Balance
This Tool reproduces one retained, source-owned water plan for a separately recorded mash and sparge process. You provide every ratio, retention rate, target and unrecovered-volume allowance; the Tool normalizes labeled units, shows the full balance, and optionally records one complete observed pre-boil comparison. It does not invent brewing defaults or decide a recipe, temperature, chemistry, efficiency, process, quality or safety outcome.
