btw, Denise, you specifically used the term "brewmaster" in your original post. This is a hotly debated term to begin with. A "brewer" is not of the same status as "head brewer," and "head brewer" does not hold the same status as "Brewmaster."
Most brewers agree that the term "Brewmaster" or "Master Brewer" requires formal education at VLB, Heriot Watt, Weihestephan, or another renowned brewing school. They also agree that the designation should not be used without years of experience to back it up.
Some brewing facilities use "Brewmaster" for the highest position in the brewery - and that entails choosing and/or formulating the recipes that will be used, choosing and ordering ingredients, scheduling what beer styles to make and when they will be brewed, selecting equipment (and parts) and keeping it in good working order, keeping the brewhouse clean and free of contamination, etc. Teri Fahrendorf is a superior example of one who has achieved this.
In many facilities in Germany, there can be several Brewmasters, and they are ranked: 1st Brewmaster, 2nd Brewmaster, etc. These may require (in addition to formal education)apprenticeships to be served for a number of years.
Some believe the term is not "deserved" until you have 7-10 years experience; others use it for PR purposes, because that is what tourists like to hear.
Back to the original question about interests and qualities of a woman brewmaster:
Yes, cooking is perhaps #1.
Ability to make decisions.
Ability to accept responsibility for occasional failures that are bound to occur in the course of brewing.
An analytical mind.
Interest in chemistry and physics.
Strength and persistence.
Artistry.
An open mind to new ingredients and processes.
Thirst for research.
Attention to sensory perception.
Hmmm....okay, ladies, what have I missed? I need some help here!
