This is one of my favorite bases right now https://www.amazon.com/365-Everyday-Value-Organic-Gravenstein/dp/B074H6YNP8/ref=mp_s_a_1_2_0o_wf?dchild=1&keywords=gravenstein&qid=1614193004&sr=8-2.
I get it at WF, but I think they will ship it. In my area, it's one of the few things WF has that is cheaper than any other store (2.99 vs 4.99).
Thanks again for the tips!
I just found this Gravenstein apple juice at Wholes Food as well: https://primenow.amazon.com/dp/B074H6YNP8?qid=1540990704&m=A1VASERKDRIISR&sr=1-145&ref_=pn_sr_sg_25_img_A1VASERKDRIISR
Looks like there have been some single varietal Gravenstein ciders made, so I might go with that.
