Just my two cents, but for best results I would freeze. For the first batch you're looking at 5 days refrigerated, minimum, for the extracted juice. Depending upon refrigerator temperatures and condition of the tomatoes, you could end up with fermented juice or degradation of quality.

Is freezing the juice possible for you? If so, that is best by far. As Carol said juice will ferment in the fridge. It also begins to break down, to separate even before fermentation begins so quality and flavor degrade quickly. Plus you also have the problems of possible bacterial contamination in a fridge which you do not have in the freezer.

Thanks! I will plan to freeze them as I pile them up.
