1
Number of unknown healthy wood type samples correctly identified in pure 4.5% MA cultures.
2
Number of unknown healthy wood type samples identified to an incorrect aroma class.
3
Number of unknown healthy wood type samples not identified to an aroma class due to <70% ownership in any one aroma class.
4
Mean percentage match of unknown healthy wood type samples to the correct aroma class identity.
