My German friends have also remarked on disappointing French teas, and that almost every infusion is based around verbena and chamomile. Even if it’s sold as something else on the front, that represents typically less than 30% of the actual ingredients and is more verbena plus something.
I’m guessing based on the “hay” description that you’re more into herbal teas. I’m mostly a fan of black teas and Kusmi and Damman are my go-to French brands. My partner is more into herbals and in over a decade never found a really good option.
My only advice is to stock up when in a place that has the teas you appreciate. I personally load up on fruit teas during trips to Germany or Austria.
Yeah, I got that the hay taste is a negative. I feel like thats more likely to come from bad herbal teas more than black, so it was a guess that you’re into herbals.
Sorry I don’t really have any actually useful advice…
