But finding the actual great German beer, the blessed helles, is not super easy in US. People seem to think all these bocks are super common in Germany, but it's actually helles what everybody drinks (and pils in the north). Helles is extremely hard to brew correctly, it requires a very specific temperature and pure ingredients.
I spent most of my vacation in US last year finding a good helles from a bar. I found one after many tries, and the closest I could get to a bavarian helles was in Weaverville, in Leveller Brewing Co. I went to thank the owner for this great beer, and he told me he studied brewing in Bavaria and brewing that beer took a lot of trial and error.
Edit: somebody soon comes to tell how easy it is to find helles in US. Yes, but it often doesn't taste how it should. Or you get some old bottled stock of Augustiner that is not a same thing as fresh Augustiner in Munich.
