7.08% pot.
That's about the same as fruit juice. Fermented dry, that would give roughly 7.08% ABV.
What it means
How sweet is that?
Refractometer readings drift once fermentation starts, because alcohol bends light differently. Hydrometers stay honest.
The math
How to convert °Bx to % pot.
Brix and specific gravity relate through a cubic fit: SG ≈ 1 + °Bx ÷ (258.6 − °Bx × 0.88). Potential alcohol is roughly °Bx × 0.59.
Example: 12 °Bx = 7.08 % pot..
