    I emphatically agree that black patent malt is not technologically
feasible until 1817.  That is what the "patent" was about; the airtight, 
evacuated kiln that made it possible to roast the malt black without 
having it burst into flames.
    However, I understand that porter, which uses chocolate malt, 
dates from sometime around 1750.  I thought that chocolate malt 
was not dependent on that technology.
    Citation, please? 

    Similarly, crystal malts of all colors and varieties are dependent
on a pressurized kiln which was developed sometime during the 
Industrial Revolution.  Anybody have the date for that?

    Knowledge is never wasted, nor is the time to acquire it.
