Just be sure to not let Guido at it unsupervised.
Your post reminded me of when Guido, at 97, was visiting for a few days.
He went into the coldroom and grabbed a half liter jar of cherries.
Sat at the table by himself and ate the whole jar, licking up every last drop of juice.
A few minutes later he is yelling at Baba, "Why can't you make cherries this good?!" on and on.... then starts dancing around the kitchen...
They were overproof Rum cherries.
