We got these beauties in June of 2020, several months before the temporary farmer’s market shutdown. I have to say that I was never able to get the same rainbow of colors shown above. Mine were red, purple and green. I waited and waited, hoping to see some yellows and golds peek through, but to no avail. The tomato promptly let me know it was ripe enough by falling off the plant when I went to check on it. Other gardeners warn growers to wait until you can at least see red on the tomato: purple and green is still not ripe.
Despite not getting any gold tones, it was quite good: firmer than most grape tomatoes, and not overly sweet — more savory. It would probably be good in a salsa, but with it’s looks, perhaps best served as is, in a bowl.
According to the plants database, Brad’s Atomic Grape is indeterminate, full sun, 75-85 days to maturity.
