Navarro’s Rosé (the Grenache-based one, not the Rosé of PN) is my favorite US Rosé and I think would be under your target. I’m not sure this year’s has been released yet.
Florida Jim (Cowan Cellars) makes a great one for $15ish and occasionally blows them out. More on the savory/food side of rose’s. The 2 best I have had from Calif. are Liquid Farm and especially the Sandhi for a bit over $20.
Best bargains in rose for my tastes though come from the south of France.
Awesome suggestions all around. So much to choose from!
2015 is going to be interesting in terms of amount of rose offered. It seems like while crop was large in 2014, 2015 roses are a totally different story.
