Antonovka or Antonówka is a group of late-fall or early-winter apple cultivars with a strong acid flavor that have been popular in Russia (Soviet Union and the Russian Empire) as well as in Poland. The most popular Russian variety is Common Antonovka (Антоновка обыкновенная), from which other cultivars are derived. In Poland, there are two varieties: Antonówka Zwykła (same, as in Russia) and Antonówka Biała also known as Śmietankowa (Antonówka White or Creamy) with considerably larger and whiter fruit ripening in late September, but also a shorter shelf-life.
