Rhubarb Shrubs and Other Drinking Vinegars


Recommended Posts

I am on Day 12 of my first Whole 30 I am looking for a way to jazz up my soda water, and I was wondering if Shrubs are considered Whole 30 at all or even Paleo? 


The Rhubarb Shrub I want to make contains:

1/2 cup fresh rhubarb, washed and chopped into one inch pieces
1/3 cup granulated white sugar
1/2 cup raw apple cider vinegar


(recipe here: http://harmonioushomestead.com/2012/05/29/rhubarb-shrub-a-drinking-vinegar-recipe/)


Obviously this contains sugar so I immediately thought no, however, a friend told me that the sugar was the food for the fermenting rhubarb and that after it was all said and done it really wouldn't contain sugar anymore.


This just sounds like it would be so good with sparking water I had to find out if I would ever be able to have it.

I don't think so. Let me explain...


We have allowed that kombucha, which is fermented tea fed with sugar, is okay as long as it has no added sugar to sweeten it on the theory that the sugar is consumed during the fermentation process. But I am not sure that your recipe for rhubarb vinegar will actually consume the sugar. I am afraid that it is not a real ferment. Mixing fruit and apple cider vinegar gives an instant fermented taste, but I am not sure that is the same thing as an actual ferment. For instance, I make pickles with ACV, but they are not fermented pickles. The recipe calls for letting the mix sit for 7-14 days until it achieves the taste you want. I am afraid that at the end, this recipe is sweetened ACV with a fruit addition.

It's not fermented. You can not use vinegar, even raw, to create lacto fermentation. The acid in the vinegar kills the lactobacilus, the bacteria needed for fermentation. 







If you want to ferment rhubarb you can, but you would do it with brine that does not include vinegar. If you google 'fermented rhubarb' a ton of recipes come up.  I've never done rhubarb but I make my own sauerkraut, kombucha and other fermented veggies. It's  an easy, fun and rewarding hobby.
