Figure 1. Comparison of ‘wine-like’ vs standard extraction protocols for tannin and colour analysis. The gentle ‘wine-like’ extraction in 15% ethanol (top) gives a good prediction of eventual wine tannin, while the standard protocol of grape homogenate extracted in 50% ethanol (bottom) overestimates the eventual wine tannin concentration.
