As you know, I'm not a veg grower either Sacha, but I do remember
seeing this recommended by Percy Thrower on the original Gardener's
World many years ago.

...They would cut bunches of grapes with a 'T' piece of stem at
the top and carefully place the 'T' in a special kind of vase filled with a
solution of water and sugar, with the grapes dangling outside.

Yes this is still a successful method of you have a glut of grapes and
a well ventilated house. We used to have a massive 'Muscat of
Alexandria' that gave wonderful crops. They would deteriorate if left
hanging on the vine, but remained in very good condition for quite a
long time if placed in bottles of sugar solution.

And for those of us who had hail today - it's arrived here - Old Tom used
to say that if it hailed you'd have three days frost afterwards.

Yes we had a few minutes of hail here leaving a bit of ice lying for a
short while. That frost didn't arrive last night though and I'm
pretty certain that we've seen the last of winter here on the coast.
