Brix:Acid Ratio (Fruit Maturity) Calculator
Calculate the Brix-to-acid ratio — the standard fruit maturity and eating-quality index.
The Brix:acid ratio balances sweetness (Brix) against tartness (titratable acidity) and is the standard maturity and flavour index for citrus, grapes and many fruits — it predicts eating quality far better than sugar alone. Each fruit and market has its own target ratio for harvest.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Orchardists and growers use the free Brix:Acid Ratio (Fruit Maturity) Calculator for an accurate answer in seconds — no formulas to remember, works offline in the orchard.
About Brix:Acid Ratio (Fruit Maturity) Calculator
Sweetness alone doesn't tell you when fruit is ready or how it will taste — it's the balance of sugar to acid that matters. The Brix:acid ratio divides soluble solids (°Brix) by titratable acidity, giving the maturity and eating-quality index used commercially for citrus, grapes, mangoes and more. A low ratio is tart and immature; a high ratio is flat and over-ripe. This tool computes the ratio so you can harvest at the target for your fruit and market.

Frequently asked questions
What is the Brix:acid ratio?+
It's the soluble-solids (Brix) reading divided by the titratable acidity percentage — a measure of the sugar-acid balance that determines fruit flavour and ripeness. It's the standard maturity index for citrus, grapes and many other fruits.
What Brix:acid ratio means ripe fruit?+
It varies by fruit and market, but many fruits eat well around a ratio of 10–20:1 — below that they taste tart and unripe, above it they taste flat. Citrus, for example, often has minimum-ratio harvest standards. Use your crop's specific target.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the orchard and your data never leaves the device.
