I became hooked on Typhoo Tea which I personally prefer over other imported British supermarket brands imported here to the USA (American supermarket tea, including the so-called "British Blend" which isn't, tends to be rather nasty in my opinion). I had been buying my Typhoo in 80-count boxes which the nearby World Market sells at a good price. When I saw the price for the 440-count package online it struck me as a great buy given that I WILL go through all 440 bags before their expiration date.What I was not aware of - and this is not a complaint or any sort of "defect" - is that the bags in the 440-count packages are "single-serve" also known as "cup size" or restaurant/catering size. This is clearly stated on the packaging displayed on the listing. But I was not aware of the difference until after my order arrived.The difference between the regular 80-count packages, other than the bags in the 440-count being square instead of round (something I don't care about) is that the tea bags in the 80-count size contain 3.125 grams of tea whereas the bags in the 440-count single-serve/catering size contains 2.27 grams of tea.As far as I can tell, it is the exact same tea, just in a different amount per bag. Whether this is a good thing or a bad thing is entirely a matter of personal preference. The important thing is to know that to receive an identical brew as the 80-count bags, one will need to use a bit less water.Apparently, the reason this size is called a "single cup" size is that many Brits will use the 80-count bag size in a teapot. But, if so, and if the pot only holds two servings of tea, then the resulting brew will be weaker than the 440-count-sized bags brewed as one serving.Another way of looking at it - on British brands of loose-leaf tea the instructions usually call for a rounded teaspoon of tea per serving plus an extra teaspoon "for the pot" if one is making a a potful. A teaspoon of tea is about 2 grams. So these 440-count bags at 2.27 grams each would qualify as the equivalent of a rounded teaspoon.If in doubt about whether these bags will work for someone who is used the the larger-sized bags in the 80-count boxes, an easy way to tell is to make a serving using about a third more water than you usually use. If you find it just as enjoyable or better, then these are a wonderful bargain. If you prefer the 80-count size bags, then be aware that there is a difference and that you might need to adjust your cup size or amount of water used accordingly or just get used to drinking it less strong.Personally, I do prefer the strength of the 80-count size as I have gotten into the habit of adding milk to my tea. Typhoo does offer an "extra strong" blend which provides a stronger brew with the same amount of tea as the regular blend. I tried it but, even though I do prefer my tea strong, I preferred the regular blend.Also, unless you are planning to serve large numbers of people in a relatively short period, you will want to identify an air-tight container to store the tea bags in once you open it - something that is mentioned on the packaging. The 80-count packages contain two airtight foil-wrapped packages of 40 each. Once opened, it will take a LOT longer to use 440 bags than it does to use 40. If one doesn't place them in an airtight container then they will likely grow weak and stale before they are all used.Again, this is a great price for what has become my daily go-to brand of tea. But those who have been buying the 80-count-sized boxes should be aware of the different-sized bag to avoid potential disappointment.
