Line spacing for all enumerate / itemize blocks (beamer)

I just wonder, how it is possible to increase the spacing between between each bullet-item (item line) using beamer?

Is it possible to adjust the line spacing with defbeamertemplate or setbeamertemplate?

Thank you so much!

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Aug 11 '15 at 8:57
• \itemsep works for beamer as well as most document classes. Aug 11 '15 at 15:59

I believe \itemsep is reset at the start of each itemize or enumerate and is given different values for different levels or when cramped. For a global value, see Global setting of spacing between items in itemize environment for beamer

\documentclass{beamer}
