Question 1

What is an alcohol dilution calculator?

Accepted Answer

A tool that tells you how much water (or higher‑proof spirit) to add to a known volume at a known ABV to reach a target ABV.

Question 2

What formula does it use?

Accepted Answer

Mass balance: V1×C1 + V2×C2 = Vt×Ct, where C is ABV (as a fraction) and V is volume.

Question 3

What is Pearson’s square?

Accepted Answer

A quick visual method for two‑component mixing (e.g., spirit and water) to hit a target ABV without algebra.

Question 4

Does temperature matter?

Accepted Answer

Yes. Alcohol–water volumes are not perfectly additive and are temperature‑dependent. The tool assumes near‑room temperatures and small error.

Question 5

Is this legal or safe advice?

Accepted Answer

No. This page is informational only. Follow local laws and safety guidance when handling alcohol.
