Oval paste type tomato, Rio is similar to Roma except larger and better flavored. If you like Roma, try Rio as your main crop for processing- it out produces Roma hands down. You might like it much better! Quite good as a fresh tomato too. Because Rio is simply so much better than Roma, you might make this your main crop caner if you prefer paste style Tomatoes. I have found it less prone to blossom end rot which plagues me with Roma.
