Apple Juice cider

[cidermaker]

hi all I have made some cider with the ez cap system out of motts apple juice the easiest juice I could find around here and I put it in the empty two liter bottles and added sugar and yeast not too much though because too much of any of those two can ruin your whole process.The first two gallon batches I made I used white table sugar while on the second 2 gallon batch I used brown table sugar.I don't recall doing anything really special after that and I let the stuff do it's thing for about 5-7 days for the first gallon batch then 3-4 days for the second 2 gallon batch .I guess my question is I have put both of my most recent 2 gallon batches in the fridge to clarify and for the most part they have I guess the part I'm not understanding is the smell is it still supposed to smell like something is rotting?

Thanks
