Nobody gets "bread and wine" in the Catholic Church. In a Latin rite church you receive Holy Communion when you are around 7 years of age, in the Eastern rites, usually when you are baptized as an infant. But, please, these are NOT "bread and wine", they only have the appearance of bread and wine, after consecration, they are the Body and Blood of Our Blessed Lord, Jesus Christ - read the second half of the sixth chapter of St. John's Gospel (John 6:22-59).
