Ubadah bin Nashit narrates: I heard Sayyiduna Ibn Abbas (may Allah be pleased with them both), when asked about "tila'" (grape juice cooked down until thick), say: "I do not know what this tila' of yours is that you bring, but something used to be brought to us that was as thick as the tar used on camels, and we would drink it and see no harm in it."
