Primula’s 1 Cup Stovetop Espresso Maker quickly produces 1 demitasse cup (2 fl. ozs) of rich, authentic espresso. Stovetop espresso makers can make quality espresso without the hassle or cost of electric espresso machines. Individual espresso makers are easy to use and deliver a fantastic cup of fresh, aromatic espresso. Primula’s distinctive design provides thorough and even heat distribution for enhanced flavor and aroma. Simply fill the lower chamber with water, fill the filter with ground coffee and place on medium heat atop your stove. Within minutes, a delicious, bubbling cup of espresso will fill your pot. Remove from heat and enjoy straight, or add milk for tasty cappuccinos or lattes. This durable cast aluminum espresso maker features a safety-release valve. One of the major factors which control the quality of your espresso is the pressure with which the water is delivered to the coffee grounds. If it is too low, your espresso will be under-extracted, while the flip side of too much water pressure causes over-extraction. Primula’s design allows you to make the perfect shot of espresso without worry as the safety release valve controls the pressure at a set, pre-determined level. This sturdy espresso maker is carefully crafted of strong, long-lasting aluminum and features a durable flip-top lid with a temperature resistant knob and handle that allows for easy, safe pouring.
