YIT- Flavored coffee can be treif even if it does not taste like meat
In addition,to rely on the the heter of taam pagum because there is soap being used when the coffee carafes are washed….. sometimes with real treif and sometimes with flavored treif- is relying on leniences and should not be done “lachatchila”. It could be they soak or pour very hot water before using soap. Is there a universal wahing system..?? Do we KNOW what is done and how it is done?
BTW, Thermoses for travel are not so expensive.
