I volunteer at a food bank, and the company that sends us our food decides what we get. Last Tuesday they sent so much produce we could not fit it all into fridges. We were trying to give away cases of the food on Wednesday, but people were turning it down because they had no place to store a case of tomatoes, or cauliflower. This was what we had left after last Wednesday’s morning give away. Not pictured the 5000lbs of watermelons, the 2500lbs of onions (those will last a lot longer).
The company that supplies us wants to move from sending shipments every other week, to once a month. This would cause even more no produce loss.
It is so frustrating to have all this food for it to go bad. Even if we got the same volume of produce, but there was variation in what it is we could give it away easier.
For the watermelons you might try to contact a local vintner. They may be able to process them into wine and/or liquor.
My initial thought was that the sugar content in watermelon would be to low to acquire any watermelon taste when made into a wine without an artificial flavoring added, apparently watermelon has more sugar that I thought. (More than peaches apparently, never would have guessed that). Twice that of strawberries…
Usually you try to aim for about 18g of sugar in 100 grams of product for the fermentation. Which I think people used that just because that’s what grapes hover around and they ferment very well without additives.
