Not a generic form stretched to fit four different spirits. Each module below is built around the real production journey for that category, with every record linked to the one before it.
Four connected record types tell the complete story of a batch — from botanical delivery through to duty payable.
| Form | Purpose | Key Fields |
|---|---|---|
| Batch Log | The core production record — maceration, distillation, ABV, yield, and the botanical recipe used. | Maceration/distillation start & end, ABV (min. 37.5%), yield, losses, botanicals list, pure alcohol (calculated) |
| Botanical Traceability | Records each delivery of a botanical ingredient from a supplier — the foundation of farm-to-bottle traceability. | Supplier, supplier lot number, quantity received/used, running remaining stock (calculated) |
| Botanical Trace Log | Ties a specific production batch to all the botanical deliveries used in it, as a line-item list. | Linked batch, botanical, quantity, unit, certificate reference |
| Duty Form | Calculates excise duty payable on a batch — reproducible for audit, years later. | Volume, ABV, duty rate per LPA, pure alcohol litres, duty payable (calculated) |
GINBATCH-2026-0031 — 20kg of juniper berries arrives from a supplier, logged and locked as a Botanical Traceability record. The batch macerates over two days with juniper, coriander, angelica root, and citrus peel, then distills at 81.4% ABV beginning-of-batch with a yield of 450L. Pure Alcohol is calculated automatically: 450 × 81.4 ÷ 100 = 366.300L. Once approved, the Duty Form calculates duty payable at £28.74/LPA: 366.300 × 28.74 = £10,528.90 — a figure that stays reproducible for HMRC review years later.
The longest pipeline in AlchoGin — six connected record types following grain all the way to a maturing cask.
+ Angels' Share Log — periodic evaporation readings, ongoing throughout maturation
| Form | Purpose | Key Fields |
|---|---|---|
| Mash Log | Where a batch begins — grain mixed with hot water to extract fermentable sugar. | Batch ID, mash temperature & pH, volume, grain items (with supplier/lot) |
| Fermentation Log | Yeast converts sugar to alcohol; gravity readings show conversion. | Start/end gravity, duration (calculated), yeast & nutrient inputs, temperature readings |
| Distillation Log | Wash is distilled and separated into cuts — foreshots, heads, hearts, feints. | Wash volume, per-cut volume & ABV, total yield (with a built-in sanity check against wash volume) |
| Cask Filling | New-make spirit goes into a cask to begin maturation. | Cask ID, cask type, warehouse location, fill volume & ABV (37.5–95%) |
| Warehouse Movement | Tracks a cask's physical movement between storage locations. | From/to location, reason, moved by, optional GPS location capture |
| Angels' Share Log | Periodic evaporation-loss measurement for a maturing cask. | Measurement date (one per cask per day), volume loss, ABV change |
WSKBATCH-2026-0012 — 1,200kg malted barley + 300kg peated malt mashed at 65°C (1,500kg total grain). Fermented 48 hours, gravity 1.080 → 1.005. Distilled from a 4,800L wash into cuts — Foreshots 20L, Heads 60L, Hearts 800L @ 68% ABV, Feints 40L — for a total yield of 920L (comfortably under the 4,800L wash volume). The 800L of hearts fills cask CASK-2026-0044 at 68% ABV — Pure Alcohol: 800 × 68 ÷ 100 = 544.000L. Six months later the cask moves to long-term racking; a year on, an Angels' Share reading shows 18L lost to evaporation (~2%) and ABV easing from 68% to 66.5%.
A three-stage pipeline — raw material intake, fermentation, and barrel ageing — all threaded together by a shared intake identifier.
| Form | Purpose | Key Fields |
|---|---|---|
| Molasses Intake | Rum's equivalent of a goods-receipt — a specific delivery of molasses from a supplier. | Supplier, Brix (sugar content), quantity, delivery date |
| Fermentation Log | Converts the sugars in the molasses into alcohol via yeast fermentation. | Linked intake, yeast type, temperature, duration, gravity readings |
| Barrel Ageing Log | Cask filling and warehouse location for rum maturation. | Linked intake, cask type, warehouse location, fill volume & ABV (min. 37.5%) |
RUM-INTAKE-2026-0009 — 2,000kg of molasses arrives from Caribbean Sugar Traders at Brix 14.2. Fermentation batch RUM-BATCH-2026-0004 references that same intake: pitched with a dedicated rum yeast strain, fermented 72 hours at 28°C, gravity dropping from 1.090 → 1.008, yielding 1,800L of fermented wash. After distillation, 180L of spirit at 65% ABV fills cask RUMCASK-2026-0021 — also linked back to the same intake — so a bottle sold years later can be traced to this exact molasses delivery.
A focused two-stage pipeline reflecting what distinguishes vodka: repeated distillation to a high, neutral strength, followed by filtration for clarity.
| Form | Purpose | Key Fields |
|---|---|---|
| Distillation Log | Captures the column configuration used, resulting strength, and yield of a distillation run. | Column settings, ABV reading (min. 37.5%), volume, run start/end, pure alcohol (calculated) |
| Filtration Log | Records the carbon filtration pass and quality-control outcome. | Linked batch, carbon filter batch, flow rate, clarity pass/fail, post-filtration ABV |
VODKA-BATCH-2026-0007 — a run through a 6-plate column at an 8:1 reflux ratio produces 600L at 96.0% ABV. Pure Alcohol is calculated automatically: 600 × 96.0 ÷ 100 = 576.000L. The linked filtration record VODKA-FILT-2026-0011 logs carbon filter batch CF-2026-018, a flow rate of 45 L/h, a post-filtration reading of 95.8% ABV, and a Clarity Passed: Yes — the batch is now cleared to link to a shop product and go on sale.
Zooming back out — the platform contains 15 controlled forms across the four spirit categories above, all following the same Draft → Submitted → Under Review → Approved → Locked workflow.
Batch Log is the parent record; Botanical Traceability, Botanical Trace Log, and the Duty Form all link back to it.
The longest chain: Mash → Fermentation → Distillation → Cask Filling → Warehouse Movement / Angels' Share.
Molasses Intake → Fermentation → Barrel Ageing, all threaded by a shared intake identifier.
Distillation → Filtration, reflecting the category's focus on repeated distillation and clarity.
