I buy the 454 gram vacuum pack of the Fleishmann's Instant Yeast and
transfer a quarter to a brown bottle I keep in the fridge, and close
the rest up tightly and keep it in the freezer. Fleishmann's has the
Bread Machine Yeast in the 2.25 teaspoon packets of 7 grams, as well as
the 113 gram jars. The instant yeast in the vacuum pack is effectively
the same yeast and is used the same way in bread makers. I have also
seen coffee can sizes of yeast in Costco here in Canada but have not
yet purchased that much, as I have no good way to store it in that
larger size. I suspect it too is the same yeast on the inside. :-)
