BEGIN UPDATE, 09/25/2018:I have been a DAILY consumer of this tea for years; I love it and I meant every word written below. Please read all the way through and decide for yourself whether or not to purchase it here. As I said, I have loved this tea for years and drink a bottle every single day. I have enjoyed the convenience of two-day shipping and having an active subscription to get regular deliveries. This item IS available to me locally, at a grocery store and at least one Asian market too, but Amazon pricing has always been lower and since it's a heavy item (a case of 12 bottles weighs 12.675 lbs), I have been happily ordering here.HOWEVER, something happened with my most recent order, that I felt needed to be shared. At least one bottle in my latest case was spoiled. There was some kind of slimy, fuzzy looking, mold-like substance floating in the bottom of the bottle. Gross! Especially because (since I can't see through the green label) I found this stuff by drinking from the bottle before I knew something was wrong.I believe this issue is caused by improper storage by Amazon before shipping (exposure to extreme temperatures could cause the plastic bottle to expand and contract, which could damage the seal - allowing mold to grow. Such damage might not be visible to the eye, as in my case. The same result could have happened due to improper handling in transit/shipping, related to temperature, but either way - this should not be happening to anyone paying good money for fresh, potable tea. It is also possible that the seal could have been damaged as a result of the cases of tea being packed in a box that is too heavy for the carrier to manage with care, so they drop it or handle it roughly because the weight is too much. Amazon needs to reconsider the packaging options for items like this!No matter the cause, I see in previous reviews that I am not the first person to have this problem, it seems to have gone on ignored by Amazon for at least two years. Please don't giv2 up on this wonderful tea, but you may want to consider sourcing it elsewhere, even direct from Ito En - to be assured of safety and quality. I tried to edit this review yesterday, but only managed to save the pictures. This is the text that explains why I removed a star from my original 5-star rating and, which goes with the pictures. Please note the "normal" bottle in the pictures for comparison; it's the one with the darker color tea inside. I also included pictures of the inside of the contaminated bottle's lid, showing something that shouldn't be there too.END OF UPDATEI meant what I said in my title for this review; that's why I subscribed to have this tea sent regularly to me. I take a bottle to work everyday. I love the stuff so much that I have FINALLY been able to kick my soda habit. HOWEVER, I feel the need to warn others about something that has been happening recently, with my last few shipments.Amazon has been shipping my the Taiwanese version of the product instead of the one clearly marked "Product of Japan." Now, with many things, that difference in manufacturing location would not bother me. But, in this case, it does. At first, I thought that the packaging had just been changed. The cases from Japan are in well-made, very sturdy boxes with handles, and the ones from Taiwan are half-box with shrink-wrap over top. Cheap and much more difficult to carry up to my second story apartment. I was prepared to accept the change in packaging without complaint - until I opened the first bottle of tea.I wrote to Amazon about the packaging issue before I tasted the tea, and of course, did not see any improvement in the next shipment. It came from Taiwan too... disappointing. Amazon should listen to us more often.I tasted something "off" about the tea when I opened the first bottle from the first Taiwanese case I received. (I didn't even know it was from there at the time.) The different taste (I really can't put my finger on what it was that got my attention, but it was distinctly different) caused me to look at the bottle more closely. When I saw the source, I realized that I wasn't getting my beloved JAPANESE tea. I know, I know it's still Ito En, which SHOULD mean it's ok, and the same, but it's not.Still, It En Oi Ocha is the BEST green tea I have ever tasted, in spite of the difference in manufacturing locations, and/or quality control in Taiwan. I would have told you that I did not like green tea at all, only a short time ago. That is, UNTIL I found this green tea, and tasted it for what it really should be. Oi Ocha is heaven in a bottle.
