NOTE: With the economy as it is, the HBD is struggling to  
meet its meager operating expenses of approximately $3400 
per year. 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. Please consider it.

Subject: IPA myth? 

>>beer made from wort of the specific gravity 1042 is not only better  
>>calculated to resist secondary fermentation and the other effects of a hot  
>>climate,<< 

This is a bit confusing and flies in the face of too many other styles. If  
the lower gravity beer was in fact more stable how do we explain the  
evolution of: Export stout, 
Russian Imperial stout, Biere de Garde, Oktoberfest and barleywines?

Subject: Keg Gas question [SEC=UNCLASSIFIED] 

G'day all, 
After changing the disconnect on my gas line so I could gas up a keg 
via the beer out diptube, I replaced the beer disconnect with the 
original gas disconnect.  Sure enough, I now have a very small 
gas leak which is a hassle, but nonetheless manageable. 

Then it dawned on me....if I'm occasionally hooking up the gas 
line to the keg and giving it a squirt of CO2 to keep pouring 
pressure in the keg, am I also inadvertantly adding some O2 to 
the keg whilst I'm at it? 

I'm not big on gas dynamics, but will a partially filled gas line 
add O2 as well as CO2 when I use it - and - is the amount of 
O2 over time going to have a flavour negative impact on the 
kegged beer? 

Cheers, 
Rowan
