When I first opened my Brewing Kit, I looked at this little jar and thought what the heck am I going to do with this....it's so small. But, after brewing some and wanting to drink a glass immediately, I realized this is the PERFECT size for me to have a glass of any caffeinated tea in the evening, without keeping me up all night long. I still like my quart size jars for daytime drinking; but night time will be the pint size. And, again, I love that they are USA made and support a cause.
