Abstract: A method of analysing spectroscopic data, the method comprising collecting spatially resolved measurement spectroscopic data of a sample for a series of measurements spots, assigning the measurement spots into a predefined set of spectral categories, based on characteristics of the spectroscopic data of the respective measurement spots, identifying groupings of the measurement spots based on their respective spectral categories and their spatial relationships, and assigning each grouping of measurement spots to a fundamental sample unit data object.

Abstract: An improved container (45) for fermentation and/or maturation of liquid products such as wine or other liquors is disclosed comprising a liquid impervious outer wall defining a zone for retaining the liquid product and a plurality of tubes (1) manufactured from individual lengths (2) of a suitable wood in edge sealing contact, the tubes 1 having seal means at one or both ends co-operable with the liquid impervious outer wall such that the tubes extend through a substantial part of the zone retaining the liquid product whereby the liquid product surrounds each of the tubes (1) and air freely circulates within the tubes.
