If less than half of those currently directly subscribed to the HBD sent in a mere $5.00, the HBD would be able to easily meet its annual expenses, with room to spare for next year.

In regards to your first question, did you not read the manual that came with your airlock calibration kit? On page 42, Section 7.1.5 "Compensation for Elevation" clearly points out that airlocks must be calibrated to a standard elevation of 802 feet (sorry, 244.5 meters) above sea level. This of course is the mean elevation of Ann Arbor, Michigan, center of the homebrewing universe. Elevation compensation is done by precise adjustment to the liquid volume in the airlock and must be checked and corrected daily. The optional micropipette kit (if your vendor doesn't carry it, it can be ordered directly through BLOW) contains a number of useful sizes from 1 through 50 micro-liters, and greatly simplifies this task. As to your last point, being a Canadian I sympathize with your plight, but brewers the world over know that a standard batch size is 5 US gallons and we just have to deal with that. In any case, one could argue that REAL metric brewers only make batches of 100 liters size, or multiples thereof. ;-) Cheers Bwian Return to table of contents
