I picked a bag full of nettles at the farm, rinsed them thoroughly (there were aphids all over them because they grew amongst the lettuce), put 'em in my french press to steep for 30 minutes (I like it strong) then voila-- nutrient-rich, organic tea, all sourced locally! It tasted like a mix of green tea, yerba mate, with a hint of wheatgrass. I think next time I will add mint leaves.
My other batch of nettle is now all dried up and waiting to be made into an herbal infusion. Will post an update.
