Query: Nasty chemical taste

I looked forward to trying this tea based on a few reviews I read here, so when the chance came to give it a try from the local grocery store before committing to buying bulk from Amazon, I jumped at it. It sounded delicious! My disappointment was huge: I've never had a powdered drink as foul as this. There was an overwhelming taste of butane or some acrid fuel tasting chemical once the powder was mixed. I tried it several times over a span of six weeks to be sure that my taste buds weren't just off for a day. Maybe in 2006 when the earliest reviews were posted, it was good, but the formula must have changed. It's not my first disappointment from Lipton, but it will be the last time I purchase a Lipton tea product. I'm so glad I avoided buying the case quantity. My advice---try a smaller package first!
