My first wife was born in Seville, Spain, and although that does not make me an expert on sangrias, having to put up with the non-stop chattering of her mother does! The only way to stop her talking was to throw some sangria down her throat, of course stopping the yack was not a matter of choice for her, rather a matter of physics. Anyways, take a cup of hearty tinto, add a 1/4 cup sugar and heat in the microwave to dissolve sugar. Add oranges, blood and others, grapefruit, in wedges with veins removed, do this by running your knife down one side of wedge and up other, wedged apples and pears, 1/4ed strawberries, really you can use any fruit you want, put all this in a large carraf, add wine/sugar mixture, pour in as much wine as you want, minimum 1 bottle, no maximum, and add, coke, 7 up, whatever to add a little bubble. Pour this over a glass of ice with squeeze of lime added as served. This is nice with a cane sugar ambar rum such as Mount Gay Eclipse or any Venezuelan brand. Garnish each glass with lime.
