I would like to rinse my grapes before making wine this year. I do understand that I may lose a little flavor, the main reason I would like to do it is to get rid of the fungicide I used during the year, I really do not want to drink it. The question is....1) Can I rinse them with a hose on the vine 1-2 days before harvest? or 2) Harvest and then rinse them on the plastic container, let them dry and crush them. Thank you very much, Roger
You should carefully adhere to the fungicide safety leaflet. Rinsing will not remove the harmful chemicals - only the vine will in the window period indicated.– skveryAug 12, 2020 at 12:31
I always rinse my harvested grape clusters manually in a big bucket of water with metabisulfite.
This gives me a bit of control:
- It is easier to remove insects, not much, but e.g. earwigs
- It is easier to remove rotten or otherwise not healthy grapes
- When rinsed, I can then immediately pull the grapes from the stalks and add them to another bucket for pressing later
It is a bit of work, but then I only harvest grapes for about 10 litres of juice.
