Below expectation. Mukka failed to deliver the promise of convenient tasty latte and produced cold "soapy" latte instead.
Positive Product Points
Beautiful construction with the glass top cover, characteristic of Bialetti quality. Relatively easy to use
Negative Product Points
Less-than-expected quality extraction Cold latte
I performed the standard "breaking in" process for a bialetti stovetop pot. First, brewed plain water to check seals and valve. Then, brewed 3 rounds of coffee and poured the results in the sink. The purpose is to get rid of the metallic taste and coat the inside of the pot with some of the coffee oil. Then I was ready to brew to drink.
I purchased the Mukka for my wife. Our morning ritual was to share a nice "lattte" moment after the kids have gone to school. I would grind fresh some Yemeni or Ethiopian beans (Anfim Grinder slightly coarser than espresso grind) before brewing the grinds in a Bialetti Moka Express. At the same time I would heat up and stretch some milk in a saucepan careful to avoid "soapy bubbles". I timed it so that milk and coffee would be ready at the same time. Then I would enjoy a shot of "espresso" before making my better half and I a nice cup of latte each. We would take our latte into the garden and enjoy 10-15 minutes of togetherness.
The Mukka was purchased to make this lengthy but enjoyable ritual easier for us.
The Mukka was for her to make her own latte at home when I away.
However the Mukka was a massive disappointment. The milk froth looked and tasted like it came from the "dishwasher" and the resultant latte was cold! The promised convenience was not worth the taste. We even did several taste tests with latte brewed from the Mukka and latte from a saucepan and normal Moka pot. No contest. The Mukka latte lost badly. Always cold. Always weak.
Good. I bought several Bialetti Moka pots (6-cup, 4-cup, 2-cup, 1-cup) from the local coffee shop before buying the Mukka from them. After a couple weeks of use, I returned the Mukka telling them the product did not do what it was supposed to do. The owner was reluctant at first to give a refund but later allowed me to exchange the Mukka for a Brikka and some beans at the shop.
