Mine is Nirvana. Had some by chance and the best I've ever had so now in going into my fourth year planting it. It's also my all my neighbor's favorite and every one I feed at our fall fish fry's. In fact of all the sweet corn varieties I've grown and thought were the best tastes more like field corn now.

I may have to try Nirvana, have tried several varieties but my favorite for years now has been Ambrosia bi-color (se).

Nirvana is a superweet so I'm not sure I could grow it every year here. There is a field a couple hundred yards from my garden that is planted with field corn on alternate years. I grow Ambrosia if I grow any corn at all. I might have to tell my brother, who has a half acre garden in Wisconsin, about Nirvana though. He usually grows several hundred row feet of sweet corn every season.

I grew Ambrosia last year and it was good but not like Miria 301BC, I might give Nirvana or Gotta Have It a try.

I also grow Ambrosia and might consider Nirvana. Where do you get the Miria 301BC seed?

I havent' grown. But Ambrosia and butter & sugar are very good.

I'm not sure where the OP has been getting seed from, but it looks like a couple companies still carry it. https://www.weseeds.com/bicolor-miraireg-301bc-corn-seeds-p-2182.html

Jimmy, My neighbor and I tried "gotta have it" and we didn't like it, no one did. It was very sweet but a weird sweet and can only describe it to dumping a few packs of artificial sugar on the cob and reminded me Saccharin, and it didn't taste much like corn.

I've been eating Nirvana all winter long, it was the only corn I ever had worth blanching and cutting off the kernels to freeze, and still so good.

Here's a couple of evaluation studies with Nirvana included and both gave Nirvana the highest score for taste and tenderness.

Supersweet Sweet Corn Cultivar Evaluation for Northern Indiana, 2015 conducted by Purdue University.

2016 Northern Organic Vegetable Improvement Collaborative which included researchers and educators from Oregon State University, University of Wisconsin-­‐Madison, Cornell University, Washington State University, Organic Seed Alliance, and the USDA.

I'm up to growing other cultivars from these studies including Miria 301BC mentioned, including some from Purdue's other yearly evaluation reports they do one each year. Here's a few from Purdue.

Purdue 2017

Purdue 2019 This year Solstice sweet corn received a 5 on flavor and don't believe I've seen any 5's, so next year I'll try Solstice but keep my Nirvana too!

again ,if you like Mirai, there are newer versions available 315BC and 336BC are still available.

336BV is a synergistic which I like better than the supersweets

John, I used to get it from Parks Seeds but they no longer have it.

beesneeds, I saw that weseeds have it but I can't find any information where they are from and there is no location on their site that I can find so don't know how trustful they are, but thanks for the osborneseed suggestion.

farmerdill, I can't seem to find anything on Mirai 336BC but did find Mirai 315BC but not alot of reviews on it, I'm going to order the Mirai 301BC and hope they aren't old seeds also going to try Nirvana, thanks everyone.
