- Winemaking Spreadsheets Spreadsheet to monitor fermentation by refractometer Simply type in the initial values for your juice, and then successive readings with a refractometer will allow you to monitor the progress of the ferment. Just fill in the columns with a red heading. You can use the graphing function of your spreadsheet software to plot appropriate graphs. Available in OpenOffice format, or Microsoft Office format. Spreadsheet to help with blending trials Allows you to blend wine treatments to do sensory analysis. For example if you have a Riesling to which you wish to add sugar, and deacidify, you can make up a sample at 10g/L sugar, and one deacidified by 5g/L. This spreadsheet will then calculate the proportions of these wines (together with the untreated wine) required to make a blend of the desired properties. Available in OpenOffice format, or Microsoft Office format. - Teaching Aids Spreadsheet to practice basic maths in grids (+ - x /) Generates grids with numbers along the top and down the side. The grids can be printed and then filled in on paper, or shown on a projector screen for the students to use their own paper for answers.
