Wine is more refined than cheese

CRA considers that a farmer may carry on activities (such as the aging of cheese or plucking of chickens) that, if carried on by another, would constitute the processing of farm products rather than farming.  However, where a wine producer also grows its grapes, the barrels used by it in fermenting the wines generally will be considered for class 29 purposes to be property used in the manufacturing or processing of goods rather than in farming.
