You can create one or more cellars to represent your Personal Collection. For example, you can have your entire collection in one cellar. Or maybe you’d like separate cellars for different locations, say upstairs or downstairs.
The best way to think of the cellar is, ‘if I wanted a recommendation, what selection do I want to pull from?’ If you have a primary house and a vacation house, you might want to keep those cellars separate so that you get the recommendation based on location.
