At first glance it also looks like it's very limited compared to a low-tech brewery. For example, I've got four different styles of beer in the fridge right now, plus a batch of honey weizen and a batch of mead both in primary fermenters following a couple brew sessions this past weekend. Whereas with this all-in-one system it looks like you're stuck with one beer at a time. Can't start the second batch until you've finished drinking the first one.
