I'm gonna say one more thing about mass produced american beers , AB , Miller etc. The large american breweries were and still may be using something called fish finings to clarify their beer quickly , it's essentially mucous from fish and snails that is pumped in to the top of a
tank of beer and as it settles to the bottom it collects microscopic particles and clears the beer which is then pumped off the top and filtered , In homebrewing I used something called Irish Moss which is a dried seaweed that takes days to clarify the brew but at least there is no animal by products in my brew , The major breweries produce millions of gallons of beer and they want to do it as quickly and cheaply as possible . Budweisser also uses rice in their beer which is a lot cheaper than malted barley so I give it the ultimate in crap award , if AB tried brewing it in germany they would have gone to jail because of the purity law in germany that was on the books there for hundreds of years , they have dropped that law in germany so they can mass produce crap like us but at least Beck's and some of the other german breweries still adhere to that law . Know what your drinking !
