Beer wort spindle 0 - 20 % without thermometer Reference temperature 70 °C

Graduation 0.5 %

Length/Ø 225 x 15 mm.
The density of beer depends on the temperature.
The higher the temperature, the lower the density and vice versa.
Deviations must be corrected accordingly. Correction tables are normally supplied with the beer spindle (see table below).
On the scale of the beer spindle, °P (degrees Plato) or %wt (weight per cent) can be read (from below; see picture below).
A value of 12 °P shows that 1000 g of wort contains 120 g or 12 %wt of extract. The brewer speaks of 12 ° original wort.
Hobby brewers can use spindles with a measuring range of 0 to 20 °P.
For more precise determinations, there are spindles with a limited measuring range, such as one each for 0 - 7, 7 - 14, 14 - 21 °P.
