Well, the comment was sound a bit harsh. Whether he/she is a novice or an expert on wine, when they worked hard to provide such information, encouragement should be placed to them rather than totally disapproval of their action. Perhaps they may do more researches and will provide more concrete and valuable knowledge of wine afterwards in response to positive feedback and encouragement. Indeed, to criticize something/someone is easy (even sometimes their criticism are not absolutely true!) but people may listen to or agree with the critiques if concrete comments are eventually provided with facts and knowledge and of course, without any bias. Cheers!
