Approx 300 750ml bottles in a 60 gallon wine barrel.
4 standard bottles of wine equals 3 liters. A standard bottle of wine is 750 milliliters; 750 x 4 = 3000 milliliters. There are 1000 milliliters in a liter, so 3000 millil â¦ iters equals 3 liters. A magnum bottle of wine is 1.5 liters, so 2 magnums equal 3 liters. A double magnum bottle of wine is 3 liters.
