I ENJOY A SMALL 4- 6 OUNCE DRINK OF WINE MOST EVERY BEFORE AND WHILE I AM COOKING. I HAVE ORDERED THESE BEFORE AND ONE CARTRIDGE DOES OPEN AT LEAST 50 BOTTLE OF WINE. I RAN OUT A WEEK OR SO AGO. THANKS FOR THE DELIVERY WHEN I VACATIONED IN UPPER NYS. THEY WERE PUT ON MY DOORSTEP WITH MAIL YESTERDAY. THANKS VERY MUCH AND THEY ARE NOT TOO PRICEY EITHER.
