It's a Nyagous!

The first tomato of the season from one of our roof top plants.

A prolific, rare, Russian tomato variety.  Beautiful, smooth, round, "black" tomatoes that are dark mohagany with dark grey-green shoulders. Nyagous is a wonderfully firm and blemish-free, 6 oz. tomato with lots of sweet, complex fruit flavors and a clean acidic finish. Up to 6 fruits to a cluster. A good market variety that has become a favorite of the Russian varieties. Nyagous is resistant to cracking. 

Thank you TomatoFest for the info.

Thank you Pat for the plant.

Is it too early to say it was the best tomato I've ever eaten in my life?
