Does anyone have any experience / thoughts on RedEspresso tea at home?

I had never heard of it until today when the barista at a local cafe pulled (brewed?) some while I was waiting. She filled the basket level, no tamp, straight into the Elektra.

Never tried the product but I have tried tea in my portafilter. It came out unbearably bitter. One issue is that tea steepping temps are low and range from 175-195 depending on white, green, oolong, or black. Also it is a bit of a nuisance to clean out of a filter basket. To make a tea latte, I get best results with tea brewed double strength (aka one tea bag/teaspoon loose leaf, 4oz water at correct temperature for correct time, and then 4oz steamed milk. In this case I abide by KISS, but I'd love to hear some user feedback if anyone has tried this product.

RedEspresso is Rooibos so it's not really tea....might as well call coffee tea too.

Anyway Rooibos has very little astringency or bitterness...the stronger you brew it the sweeter and more syrupy it gets so I can see how it would do well in an espresso machine.

Real tea (camellia sinensis) on the other hand will quickly get unbearably astringent or bitter or both when overbrewed...depending on the processing most (other than green, white and yellow tea) are best brewed 95-100°C (200-212°F) but pressure is a big no-no even getting smushed a bit by a french press plunger can damage the result, so I imagine they'd be a disaster in an espresso machine.

Thanks for the explanation, Tera. I did not think to see that redespresso might be rooibos. Good catch! No wonder I got superiorly awful results with tea in my machine. Maybe I'll have a go with some rooibos!
P.S. I've got a baby camellia sinensis stretching out it's little branches on my patio as of a month ago 3 more years... Haha

BTDT: espresso machine and vac pot.

Rooibos is a rich red herbal tea. Unlike green teas, it does not produce bitter results at higher brewing temperatures. Espresso machine brewing produces an underextracted result, but vac pot and French press work very well.

Sure, you can call it "red espresso" for marketing purposes, but this is an herbal tea. Nobody in their right mind would ever mistake it for coffee.

I have tried it in my old Silvia. It is not real good as a straight shot, but it is a nice drink as a latte with honey. A local coffee shop serves it as a large latte with honey drizzles on the top and it is delicious. It comes pre ground in the bag and the flow tends to be fast. It is a nice drink to sip on after you get your caffeine from real coffee. I think it expands in the basket more than coffee, so you can't dose too big. It's worth a try.
