При приготовлении слоистых коктейлей без определенных знаний не обойтись.
И самое главное, что необходимо - учитывать плотность напитков, входящих в состав таких алкогольных коктейлей.
Для этого можно использовать предлагаемую таблицу плотности напитков. Нужно помнить, что плотность напитка -однородного, не смешанного - тем меньше, чем больше в нем алкоголя. И, соответственно, наоборот.
