They should love it if not in excess, as with other worm food. The alcohol might be harmful to them but will break down quickly if there is plenty of air and bedding. So mix with cardboard for example, and in a bin where they have room to stay away until they are ready to go at it. If you want to be careful, start with modest amounts and see how they react. But my guess is that with enough bedding they will love it and go after it quickly.

One additional suggestion: mix in a handful of your existing compost from the bin to the stuff you're adding. This will let the microbes in the mix that work with worms colonize it faster. And don't worry about the alcohol thing too much, it would likely only be an issue of it was really concentrated. Otherwise what you're adding is just like any worm food - figure out if too wet, etc.

Awesome thanks for the info. i have pounds and pounds of these berries that have been thrown away before. i love being able to use em one more time.

Let us know how it goes. Since it's been pre-treated for them and soft, it should be almost perfect for them. Is this stuff pressed out and dry? As you experiment with it, and if it's pressed and dry, it may need less bedding, but too much bedding is hardly ever a problem. So err on the side of lots of bedding as you start with it. You could also put a bit in a corner and just see how quick they go for it.

it's pretty dry. I squeeze as much juice as I can out for the wine. Really more of a fruit paste in the end.

What kind of berries? Now I'm just asking because interested in what kind of wine you're making. But almost any berries like this will be excellent worm food.

I wonder if you can use the leftover berries for some sort of Rumtopf? [Rumtopf does not have to be made with rum but it does need high alcohol content, now that I'm thinking about it. I used Wild Turkey, so maybe the wine berry mash will not work after all. I'm leaving this note in though. :-) ]

I have several jars 'brewing' now from a peach harvest this spring.

Another idea is use it to make muffins. After the peach harvest was done, we had apples. I juiced many and used the left over 'mash' from the juicer to make some incredibly edible muffins, most of which went into the freezer. Google berry mash maybe.....I tried this but did not get much return. Here's the apple mash muffin recipe. I did juice up some carrots and ginger too. These are just so darn good!

Carrot Apple Ginger Tea Cakes

• 2 cups carrot/apple/ginger
  pulp
• 1½ cups flour (all purpose
  or whole wheat pastry, or a combination)
• 2 teaspoons baking powder
• rough chop pecans or other nuts of choice
• ½ teaspoons cinnamon
• ¼ cup sugar
• ½ teaspoon salt
• 1¼ cups milk or rice/soy
  milk [I used almond milk]
• ¼ cup canola oil
• 1 teaspoon vanilla extract [ed note: almond extract is WAY better]
• mini dark chocolate chips
  (optional) [we did not like the choc chips, too sweet]

1. Preheat the oven to 400°F,
   and grease a 12-cup muffin tin.
2. Combine the flour, baking
   powder, salt, nuts, cinnamon, and sugar in a large bowl and stir with a whisk or
   a fork.
   In a smaller bowl, combine oil, milk and vanilla. Pour the wet ingredients
   into the dry and gently combine, being careful not to over mix. Fold in
   the pulp and chocolate chips, if using.

Scoop into muffin tins and bake for 18-22
minutes. Cool in pan for 10 minutes, before removing tea cakes to a cooling
rack to cool completely.

I'm using wild blackberries. they make some awesome wine.

What to do with "drunk worms" they just might get extra frisky. (:-)

Sounds great. I think with this you may not need as much Browns as they will be pressed and I recall are high in stuff like fibers. But start with more cardboard etc until you know how the worms like it.

Fermented food is the best. Means it has been broken down by microbes, which the worms need. Another good food is spent brewery grains. Now there's some fermentation for ya! Vermicomposting
