Yeah there are certainly some industries that lend themselves to this more than others. For example, it makes sense for Loro Piana to own Cashmere goat herds so that they can have the best possible supply of cashmere for their knitwear. Hermes own cattle farms for the same reason, they can remove things like barbed wire from their fields which can cause damage to the finished product. Goat and cattle herding aren't yet an industrial process like making certain grades of steel or making glass bottles (for the champagne producer) though, so while it makes sense for vertical integration in some areas, it might not in others.
