Which test do I need?
Pick what you're working with and what's going on. Get the tests that answer it, with price, sample size and turnaround.
Microbial risk check
Enter pH, free SO₂, sugar and storage. Get a Low / Medium / High read for Brett, spoilage bacteria and refermentation, and the qPCR test that settles it.
Sampling planner
Style, pick date and bottling plan in; a dated testing schedule from maturity to bottle out. Print it for the cellar wall.
SO₂ calculator
Molecular SO₂ from free SO₂ and pH, the free SO₂ you need for your target, and the PMS or SO₂ solution to add for your volume.
Sugar & alcohol
Brix to Baumé, specific gravity and potential alcohol, plus sugar additions to lift alcohol where permitted.
Acid & nutrients
Tartaric addition to reach a target TA, and DAP to reach a target YAN, with the caveats that matter.
