I would tend to agree with putting it on the Brewery DB Service class-level with a memoized instance variable in the method. That make sense? Something like:

```ruby
class BreweryDBService
  def self.client
    @client ||= BreweryDB::Client.new do |config|
      #...
     end
  end

  def client
    self.class.client
  end
end
```
