<<Disclaimer: Verify this information before applying it to your situation.>> Hi all - If you are concerned about the possibility of wheat-based glue in tea bags, please keep in mind that there is the option of loose tea and a tea strainer. For example, the Republic of Tea has many many wonderful loose teas - don't even know if they offer tea bags. While tea bags are extremely convenient, carrying a small tea strainer and a plastic container of tea is certainly an option. Chris Silker Minneapolis MN
