Due to increasing production costs and the demands for Cross Compliance an easy and precisely documentation of working time is getting more important in agriculture and viticulture. Whilst smaller enterprises may ignore the costs of production an improvement in wine production can only be achieved if a producer is able to trace his effort and gets a precise idea where and how many working hours are spend during the entire production process. Especially in vineyards the grape producers have just a chance to make profits whether they are able to increase yields or getting a better efficiency by reduction in working hours. Other producers with direct marketing often ignore the factor of working hours while calculating the prices per bottle of wine. The labour hours of the family members in small businesses are generally unpaid and mostly uncalculated. With the help of a GPS documentation software, the wine growers will be able to record and analyse the required time of every production step individually. Implementing such technologies may assist finding possible savings of viticulture work and provides all legal requirements including Cross compliance. The aim of this study was to investigate several issues of vineyard cultivation like various degrees of terrestrial inclination, different mechanisation systems, trellis systems, and strategies for wine quality intensification. The first part is about a modern interpretation of wide row vineyards where the distance of the rows alternate between 2 and 4 m width. The amount of labour required within an experimental vineyard was approximately 85.2 h ha-1. The second part deals with three different education systems in one vineyard, which were compared to each other to find the strategy with best ratio of quality to efficiency. The third part covers aspects of labour efficiency comparing intensive cultivated vines for the production of high price wines versus an extensive cultivation for basic wine quality for ‘Riesling’ and ‘Pinot Noir’ grapes. The result of the intensive treatment was 533.4 h ha-1, compared to only 181.8 h ha-1 under extensive treatment.
