Seven excellence for determination of e.g. pH value or conductivityBeer is an extremely complex drink. More than 800 components
that contribute to the taste of beer have been identified. Not only do the
ingredients influence, the taste and properties of the beer, but also the
brewing process with each individual step such as grinding, mashing,
temperature, cleaning, boiling and fermentation, as well as the equipment and
handling itself.
METTLER TOLEDO offers you the appropriate instrument for
each of these analyses. One of the most important parameters in brewing is the
sugar content of the original wort. This dissolved sugar is mainly obtained
from malt, but also contains other ingredients and is called
"extract". During fermentation, the yeast present in the wort
converts the wort extract into new yeast cells, ethanol, CO2 and flavors - the
amount of extract decreases steadily over time. To monitor this process,
brewers typically measure density, specific gravity (SG) or refractive index
over time. The measured value is converted to the sugar content in °Plato (°P)
and plotted on a fermentation curve over time to visualize the fermentation
process. 1°Plato corresponds to 1 g extract in 100 g wort.
Simple density measurement with the portable Densito deviceThe METTLER TOLEDO density meters and refractometers can be
used to measure wort, extract and alcohol content and provide fast and accurate
results. The benchtop meters have a precise Peltier temperature control, so
that the beer sample is always measured at the correct temperature. Thanks to
the integrated concentration tables, e.g. specific gravity or °Plato can be
converted without effort. The portable Densito density meter from METTLER
TOLEDO automatically compensates the measured density to 20 °C and also
calculates the wort in °Plato.
Reliable analyses with the UV/VIS spectrophotometerUV/VIS spectrophotometers can measure a variety of other quality criteria of beer, such as color, taste, bitterness and total carbohydrate. The measurement of the above-mentioned quality criteria according to EBC methods (European Brewery Convention) or ASBC methods (American Society of Brewing Chemist) can be carried out with just one UV/VIS Excellence instrument from METTLER TOLEDO without great effort, efficiently and, if desired, automatically. Accurate and reliable pH measurement of beer is required to preserve the characteristic texture, taste, color and storage stability of each beer type.
InLab Versatile Pro is a flexible sensor suitable for this application and is compatible with both benchtop and portable pH meters from METTLER TOLEDO. The pH sensor is not only user-friendly, low-maintenance and cost-effective, but also provides fast and precise pH results for daily beer analysis.
Comfortable multiparameter analysisMETTLER TOLEDO offers the possibility of combining the individual instruments, including a sample changer, into a multi-parameter system to determine all desired parameters in just one measuring procedure and with just one keystroke. The measured data is then transferred to METTLER TOLEDO's LabX® software, which calculates, for example, original gravity, apparent extract and alcohol content using MEBAK formulas, density and refractive index. Color and pH value are obtained by direct measurements and displayed as raw values.
After sample analysis, the system is automatically cleaned to prevent cross-contamination. Performing four measurements simultaneously with a multiparameter system instead of four individual instruments increases efficiency and eliminates transmission errors. In addition, simultaneous measurements prevent inconsistencies in results that can occur due to changes in the sample over time, such as loss of ethanol.
