The Oracle offers relatively quick operation: From a cold start, it takes about 5-7 minutes to reach operating temperature. Once heated, it can produce an espresso shot in under a minute. A complete milk-based drink like a latte can be prepared in about 2-3 minutes. The dual boiler system allows for simultaneous brewing and steaming, increasing efficiency. While not the fastest machine on the market, the Oracle's heat-up and drink preparation times are competitive for its class and quality level.
