True. But that unpredictable change in tasting notes is the enemy of commercial packaged coffee: your box of illy, carte noir, maxwell house, nescafe, nespresso MUST taste the same every time, and MUST have a stable cost of raw material (apart from baseline coffee prices fluctuations). The same happens for chocolate and tea (lipton's and twining's teabags can be a mix of 20-30 tea varieties that change continuously)
