These hop farms are very, very intensive from a capital expenditure standpoint. You need lots of land, but also these trellises, or whatever they put up with the wiring. They grow really tall, and then they have special tractors that come and cut the vines down. To get back into it is going to be a massive expense for a commercial-sized hop producer to undertake.
But to answer the first part of your question on what did it in, I would say probably pricing was the thing. It's such a competitive global marketplace that this probably had an impact on Canada as a smaller hop-producing country, on influencing its current position.
