My first shot of it was like that:
Round mellow warm taste, rich aroma, perfectly balanced coffee. A bit muted fruits and not too heavy body, not too light and wonderful mouthfeel. Taste was mainly honey and peach with just a tiny touch of a bitter note (like placing it on the dry side if comparing dry vs sweet wine) and then chocolate aftertaste.
Then with slightly lower temp:
lighter cup, still balanced, but molasses rather then honey and more fruity notes, cherry. The end of cup chocolate, but not bitter one - milk chocolate. And then cherry aftertaste.
I was brewing a tad more volume then normale, at around 91C (and lower) and 14g. Then the other time I made finer grind and temp up and I got normale,
a cup similar to yesterday morning, just the fruits were a bit more enhanced and present at the finish and chocolate aftertaste sweeter.
Then I raised temperature to 92C and dose to 15g and I got the most of it really - like the first shot, but fruits more vivid and the bitter chocolate aftertaste. Awesome taste, I love it!! A kinda perfect espresso cup and repeatable - somehow first time in my life I got coffee that I like that much! Then I brewed it as singles instead of doubles - at 9g very creamy cup, with fruital variety and creamy aftertaste. Then I got one shot a bit too far and it tasted completely different - deep earthy notes, then some sweetness and some orange notes in the end.
Then I made a comparison with Caravel - 10g in the Caravel basket and about the same temp (measured in the boiler). It tasted creamy, leaving a buttery note for the end, but the fruity aroma and taste was plain - lack of complexity in comparison to Vivaldi. Also with a slightly smaller dose result was similar cup. I didn't go further with Caravel for I am not much of lever maniac, I have to have much more practice to go really for lever tasting of specific beans.
And for the very last, I made a bit of experimentation and reverting again to doubles on Vivaldi, I lowered the dose to 13.3g and made the grind finer one whole point, temp same. Result was amazing to me - no honey, no chocolate, definitely lighter body, orange aroma, grapefruit notes and intriguing wooden taste, followed by some smokey towards the end and leaving this as goodbye - grapefruit and smokey with a touch of a slight bittery.
It's first time when I discovered a whole world of different tastes in one same beans. Usually after I dialed in a coffee, I was drinking it mostly the same, occasionally alternating between singles and doubles and sometimes brewing on Caravel. Most times if I drifted from the point I matched the taste was getting poorer or I did not discovered anything I could really appreciate much.
