The hopping specifications are very different owing to the introduction of hop extract. Meaning that the hopping rate can't be given in gm/hl any more. Instead, active bitter substances are specified. Not really sure what that means. But at least the relative hopping rates are still obvious.
Several new ingredients have been added, notably amongst the adjuncts, where rice grits and maize grits have appeared.
On the sour side, there much of interest. Dekkera bruxellensis - Brattanomyces to you and me - is specifically mentioned. Also, that it was only for Porter. Interestingly, no restriction was placed on the use of Lactobacillus. You would have thought that was only appropriate for Berliner Weisse.
What was lactic acid being used for? Was it as a souring shortcut for Berliner Weisse? Or did it have some other use?
Berliner Weisse had to have a minimum of 30% wheat malt. While Weizenbier had to include at least 20%.
