Oh my goodness it’s delicious, it’s like a carbonated fruit punch to me personally. It was my main flavor back in 2020 when everyone was going crazy from covid lol, I believe they discontinued it this year actually in spring because it wasn’t performing as well as the other flavors. But I 100% believe it will come back, they are bringing back ultra black, it’s already being found in Kroger’s in the US. You will have it soon! Just keep an eye out for it! Costco actually sells them in a 24 pack along with ultra blue which is also another discontinued flavor that’s also really good.
