To Keep Grapes

Ingredients

Directions

Prepare and pack

  1. Gather grapes on a dry afternoon before they are fully ripe.

  2. In a clean, dry barrel, create alternate layers of wheat bran and grapes until full. Ensure grapes do not touch each other and finish with a layer of bran.

  3. Seal the barrel tightly to prevent air from entering.

Restore freshness

  1. To restore freshness, cut the end of the stalk of each bunch and place white grapes in white wine and black grapes in red wine.

What each ingredient does

Grapes
The fruit being preserved, whose freshness depends on staying dry, unbruised, and separated.
Wheat bran
Dry packing that cushions the grapes and keeps them apart from one another.

The step that matters

Keep the grapes from touching. Grapes that press against each other can bruise, and mould spreads easily from one damaged berry to its neighbours. Separating each grape with bran limits that spread.
