Would this be shehakol or boreh pri since the chia seeds are visible in the water even though they are very small? Would the concentration of chia seeds in the water matter?
For those unfamiliar:
I'm inferring from this article that the bracha is shehakol. Here's why:
Even if this drink were to be considered "chia juice" the bracha would still be shehakol, as this is the common halachic rule on all fruit juices except for olive oil and wine. In this case, I doubt this is chia juice.
I doubt that the chia seeds impart any flavor to the water. Thus, this would be in the similar ruling as over-diluted wine which would make it shehakol.
Not mentioned in the article is the concept of ikar and tafel (main and subordinate.) It seems clear that the ikar here is the water and you are drinking this for the sake of the water, not for the seeds which are just adding a bit of flavor (if, in fact, it does.) Thus, again, shekol. However, if you were to chew the seeds, separately, you may have to make two brachot - one for the water and one for the seeds, as you are deliberately gaining benefit from the seeds.
