Measurement of wine color and tannins involves spectroscopic analysis in the UV and visible region. The test protocols are complex and are hampered by the need make multiple wavelength measurements. A typical spectrophotometer can only make one wavelength measurement at a time. In addition, the assessment of total phenols requires measurement of the sample at 280 nm requiring the use of an expensive, difficult to clean and easy to break 1 mm path length quartz cuvette. Even with a 1mm pathlength, most red wines still require 5 to 10 fold dilution in order to keep the absorption at 280 nm near 2.0 OD, further complicating the test protocol. In this application note, we report the performance of a new short path cuvette, the SpecVette™ with an Ocean Optics HR4000 spectrometer using a balanced Deuterium- Halogen light source to measure the absorbance of undiluted red wine samples from 250 to 650 nm. A DOS routine was written to automatically collect and transfer ten sets of data from the SpectraSuite software into and Excel™ spreadsheet. Data was collected from either ten different cuvettes (inter-cuvette measurements) or from a single cuvette that was repeatedly measured after removal and re-insertion into the cuvette holder (intra-cuvette measurements). The ten sets of data transferred into the spreadsheet were averaged at each 0.25 nm interval across the entire spectrum and the standard deviation and % error calculated. The standard deviation of the measurement at each 0.25 nm from 250 to 600 nm was plotted. The % error across the same range was plotted separately below the spectrum.
