I never know what people mean when they say, "acid taste."
By 'acid' do you mean bold/assertive/not bland/not sweet?
We tried Azoychka this year and it was a beautiful shade of yellow without so much as a hint of sweetness. It didn't have that mellow, sweet/fruity flavor you find in a lot of yellows. It was much more assertive and 'red tomatoey' in flavor.
