The little bottles can also be used to test the invert of each bottle right after the season. It hardly takes enough syrup to notice any is missing from the bottle

The temp test kits last year had an expiration date on them, Nov, 2011. You should get a new kit every year. After they expire I open them, dump the glycerine and run them thru the dishwasher. I also do the same for sample bottles whose batch has sold out for over a year. Then I reuse the bottles and buy a new cap. I do not reuse glass containers to sell syrup in, just home use.
