Potato wine

On making some potato wine,
I added yeast and that was fine.
It bubbled up and made a foam,
Which soon took over house and home.

My children thought it was great fun,
They told their friends and everyone.
Soon neighbours came from near and far,
To see if they could buy a jar.

I corked it, bottled it, stacked it high.
Made so much cash I wonder why
A taxman came, a new-found mate,
Who wobbled home with half a crate!
