[Tex/LaTex] Getting new line in title

tikzpostertitles

How do I make the title of this document break up and center-justify? \ doesn't work.

\documentclass[25pt, a0paper, portrait, margin=10mm, innermargin=15mm,
blockverticalspace=15mm, colspace=15mm, subcolspace=8mm]{tikzposter}
\usetheme{Simple}

\title{This is a very long title that I would like to break up and center-justify} 

\begin{document} 
\maketitle
\end{document}

Best Answer

Use a \parbox

\documentclass[25pt, a0paper, portrait, margin=10mm, innermargin=15mm,
blockverticalspace=15mm, colspace=15mm, subcolspace=8mm]{tikzposter}
\usetheme{Simple}

\title{\parbox{\linewidth}{\centering This is a very long title that I would like to break up and center-justify}}

\begin{document}
\maketitle
\end{document}
