Lab readings, batch costs and the additions log

Every wine's detail page carries three record-keeping tabs — 🔬 Lab, 💰 Cost and Additions log — so analyses, spend and cellar additions all live alongside the fermentation history.

Record a lab reading

1. Open the wine and switch to the 🔬 Lab tab.
2. Press + Add reading.
3. Choose the parameter: Brix, pH, Titratable Acidity, Volatile Acidity, Free SO₂, Total SO₂, Residual Sugar, Malic Acid, Glucose + Fructose, Colour Density or Turbidity. The value field shows the unit and a typical range as a hint (e.g. pH 3.1–3.8, free SO₂ 25–40 mg/L).
4. Optionally set the method (manual hydrometer/refractometer, Ripper titration, enzymatic, external lab) and attach the reading to a specific batch.
5. Press Save reading.

The tab shows a tile per parameter with the latest value and date, plus a full table of every reading. Delete a mistaken entry with the ✕ that appears on hover.

Track batch costs

The 💰 Cost tab builds up your cost of goods:

1. Press + Add cost and pick a category: Fruit / Ingredients, Additions & Chemicals, Labour, Equipment, Packaging, Services or Overheads.
2. Enter a description, and either a quantity with unit cost — the total is calculated automatically — or the total directly. Currencies supported: GBP, EUR, USD, AUD, CAD.
3. Optionally attach the entry to one batch, or leave it as All batches.
4. Press Add entry.

The summary bar shows Total cost and Cost per bottle. If MakeWine doesn't yet know your bottle count, type it into the small field beside the dash and press Calc to get the per-bottle figure. A category breakdown and a running cost table sit underneath.

Keep the additions log

The Additions log tab is your record of everything that went into the wine:

1. Press + Log addition.
2. Pick the type — SO₂ / Sulphites, Campden Tablet, Yeast Nutrient, Fining Agent, Acid Adjustment, Oak Product, Tannin, MLF Bacteria, Enzyme, Colour Additive, Sugar / Sweetener or Water Addition.
3. Record the product name and manufacturer (e.g. EC-1118, Lallemand), the quantity and unit (g, mL, g/hL, ppm and so on), and which batch it went into.
4. Use the notes field for the dose rate or purpose, then press Record addition.

A tidy additions log pays off later: it is the audit trail inspectors expect, and it seeds the ingredient declaration if you go on to publish an EU e-label. Together the three tabs mean a single wine page can answer "what's in it, what state is it in, and what did it cost?" at any point in the wine's life.
