Dandy Blend? (gf coffee substitutes)

[kl5]

I am avoiding inflammatory foods, including wheat, while I am waiting for blood work to come back. (I posted a while back about eliminating gluten and got really helpful replies. Long story short, my husband talked me into getting tested for celiac before cutting out gluten. I found a good doctor and went in yesterday.) Anyway, one of the things she's asked me to cut out is caffeine. I was off completely for a while and really enjoyed Dandy Blend in the morning. When I ran out I went back on the tea (and coffee on the weekends) and am now experiencing the joy of caffeine-deprived headache and brain fog.

So, today I went to the Dandy Blend website to reorder and noticed that it contains rye and barley. Despite this, they claim it is gluten-free:

DandyBlend is made from extracts of barley and rye, not from barley and rye themselves. The roasted grains are mixed with the roasted roots, are ground, and then the water-soluble components (nutrients, minerals, biologically active substances) are leached out of the mash by hot water, just like you do when making tea. The liquid extract which is collected at the bottom is then spray dried to make the powder which we then call DandyBlend. Why no gluten? Gluten is not water soluble; it only dissolves in alcohol. Therefore, since no alcohol is used in the extracting process, all the gluten stays back in the mash. Tests done by Eliza-Tek Laboratories confirm the absence of detectable gluten in Dandy Blend.

Does this sound plausible?

And even if it does, has anyone tried the Mountain Rose Herbs herbal coffee? I was considering ordering that instead, as it sounds really good. (For what it's worth, I am a no sugar in my tea or coffee kind of girl.)

Thanks.

Doesn't sound plausible to me. (Sorry for short post, needing a nap.)
