For many years we grew only one kind of cherry tomato, "Sun Gold". We occasionally tried other varieties (since people are used to red cherry tomatoes and Sun Gold is orange), but didn't find any that taste as good as our pick.
When we first started growing tomatoes, we had a variety that did well for us and tasted good so we grew that one. After growing it for a couple of years that variety disappeared from the catalogs. We had to scramble to find a substitute. Since then we grow 3 or more new varieties every year on a trial basis. Most of them don't make it, but we now have several varieties we depend on. If one disappears, we have others that will work.
I finally decided to do the same with cherry tomatoes. In five years of trying other varieties, we have found a couple of good ones, but none to match the Sun Gold.
We grow the various varieties in our cherry tomato maze, which acts as a kids' entertainment and educational activity as well as a testbed for our variety trials.
A couple of years ago we found that pints of mixed cherry tomatoes were popular so we started selling mixed boxes.
This is a mixture of varieties from which we fill the pint boxes. It includes a variety of colors and shapes. I can't identify them all from the photo, but I have a map that shows where they are planted so I can identify them when picking.
