Just want to piggyback on this for others reading: s/he’s right. Rosa will either refund you or send out a replacement if you contact customer service and express your distaste. They’ve always been good about this sort of thing (so please keep it this way and don’t abuse it!). Like many, I had some digestive issues with 1.6, and they replaced what I didn’t drink with 1.7 as soon as I asked. Some of my 1.5 was way too close to expiration when I got it, and they replaced the full one-month supply. And I just got a box of 2.0 to replace the Nectar I’m now using to treat my new deck. All the neighbors love how lemony fresh it is.
P.S. Apologies to anyone involved with designing or selecting the flavor profile of Nectar who’s read any of my awful Pledge jokes so far. I have virtually no palette and thus no place judging flavors for anyone but myself.
