There's also the difficulty of people who cannot or should not drink alcohol, even in tiny quantities. This is addressed by the use of "mustum," which is what vinters call freshly expressed, natural, untreated (that is to say, not pasteurized) grape juice.
I was reading the account of a priest, Walter Ciszak, who was confined in Soviet prisons and labor camps for 20+ years. Other prisoners smuggled him handfuls of raisins, which he soaked in water and then squeezed out the juice: this he used for saying Mass.
Thanks!
Fr. Ciszek was a great man. I hope he’s been praying for me, because I’ve asked!
Raisins are also what the World War II POWs used to make bootleg distilled alcohol ... not potatoes, as shown in the movie of “The Great Escape.”
