Calculators¶
Working tools, one page each. Every bench shows its model, the constants it uses with a confidence tag (High / Med / Low), the test vectors it checks itself against on load, and the open points still to settle. They are aids for planning and self-assessment, not measurements: the probe, the refractometer and the assay are the authority, and the pages say so.
Each bench also runs on its own page under /assets/apps/ if the embedded frame is awkward on a
phone.
Benches¶
| Page | Summary | Version | Updated |
|---|---|---|---|
| Base Dose and Water Activity Planner | Web port of the fruit-maillard-prep base solve: potassium bicarbonate from each ingredient's TA and native pH by acid speciation, the 80 % two-pass procedure with a predicted-versus-measured log, and the Brix, water-removal and water-activity side of a Stage B reduction. | 1 | 2026-09-18 |
| HCA Dosing Bench | Turns the hydroxycinnamic-acid dose maths into a working tool: target ethyl phenols to precursor mass, stock volumes and a staged, taste-gated schedule (or the inverse), stock make-up and labels, and the toxicity and airlock sanity checks. | 1 | 2026-09-18 |
| Cyanide Dose from Fruit Kernels in Beer | How much bitter almond, apricot, sloe or stone-fruit kernel can go into a secondary before one bottle exceeds the acute reference dose for cyanide. | 1 | 2026-09-18 |
| Marzipan Flavour against Cyanide Cost | How much marzipan a kernel charge buys, what it costs in cyanide, and which route gives the most flavour per hazard, with a flavour-intensity scale. | 1 | 2026-09-18 |
| Measuring Brix in Pastes with a 0–32 Refractometer | How to read a 60–68 °Brix cook paste on a brewing refractometer by gravimetric dilution, with the corrections a naive ×4 misses (pulp, temperature, SG scale), error propagation, water-activity estimate and a mass-balance cross-check; interactive bench. | 1 | 2026-09-18 |
| Measuring pH in Thick, Dark Cook Mixtures | How to get a trustworthy pH from an opaque, viscous cook paste: a slurry reading corrected back to the paste by charge balance, and an electrode slope and offset check. | 1 | 2026-09-18 |
