The Oster Optimal Brew™ coffee maker uses “blooming” to saturate coffee grounds before brewing. The blooming process happens at the start of the brewing cycle to help extract the fullest flavour from the grounds. When combined with a high brew temperature of up to 205° and faster brew speed, the end result is exceptional tasting coffee.The Optimal Brew™ coffee maker keeps coffee warm and fresh inside a double-walled, stainless steel thermal coffee pot — there’s no need for a warming plate. Wake up to the smell of freshly brewed coffee thanks to this Oster® coffee pot’s Delay Brew — one of many programmable features. Too busy to wait for the pot to stop brewing? Use Pause’n Serve to pour yourself a cup before the brew cycle finishes.
