Default Weird hydromter readings

A little while ago I measured my brew with the hydrometer and it read.


OLD
Potential alcohol 4%
triple scale1.032


I took my readings today and got this.

NEW
potential alcohol 1%
triple scale 1.010

after each time using the hydrometer i tested it with water to make sure it was reading correctly and it seemed to be working fine.

can anyone explain my results? I'm baffled

Yes. Your first reading was 1.032. The second reading was 1.010. That means the beer fermented, as alcohol is lighter that water and so the reading decreases.

The potential alcohol % scale is virtually useless for beer brewers in situations like this- so please ignore that.

At the present time, your ABV is 2.89%. That's a bit low, but so is an original gravity (OG) of 1.032. Perhaps that reading was incorrect? A final reading of 1.010 is appropriate for beer, and seems to be correct.

What was the temperature during your initial reading? If it was still hot from boiling, that will throw off the reading.

Potential

Once a brew is fermented the potential has been realized. 4%-1% ~~ what yooper said.
