I thought I might just throw in a slightly different viewpoint into this discussion. My day job is as a hardcore biochemist and based on this expertise I have never had any doubts at all that there is absolutely something to LODO. So, I investigated it. I tried all of the beers I could get my hand on that were purportedly LODO - fresh and in cans. I didn't really care for them. Yes, I have cut beer-drinking swathes across Germany a couple of times and I wasn't blown away by any of the beers. Nevertheless, I went full-on in adopting LODO practices into my own brewing (stopping just short of a stainless chiller, but I used Brewtan B). It definitely changed the qualities of my beers to be more like the commercial LODO beers I had tried. Success! .. .. except I didn't really care that much for the beers. It seems that I just don't really like the "it" factor.. ..maybe that goes hand-in-hand with preferring hoppy beers? I continue to be obsessive about LODO on the cold-side - this has a huge impact on preserving the integrity of flavours and the longevity of the beer (particularly hoppy ones). Regarding LODO on the hot-side, there is definitely something to it but I can no longer be convinced that it should be considered as part of best brewing practice. My feeling is that it is another knob to twiddle to achieve flavours that one may or may not like, akin to liking or disliking hoppy styles or beers with/without lots of crystal malts.
This is so close to my LODO experience that I thought I'd forgotten writing the response. LODO DOES make a difference. I brewed about 30 batches this way after it was first talked about and my beer was VERY different. I haven't been to Germany, but have had beer served from fresh kegs that were bought in (refrigerated transport), to near home. I get what 'it' is, but prefer other beers. I got 'it' from my LODO beers, but preferred some of my other beers. One of my favourite styles is English Bitter which, as noted earlier, is often brewed with major splashing. I brewed some LODO and it lost of the rich fruity flavours that I like (which I now know are oxidised flavours) - it was nice and fresh tasting, but not the same. I too now use LODO techniques on the cold side (keg spund etc.) and like what it does for my beer. IME, cold side LODO is what is critical for hop flavour and aroma.
I find it interesting that LODO brewers keep referring to the quality of Belgian beer as well as German, but a look at Belgian techniques will show that some of the best beers from the region are not LODO. For example, many (some?) use copper kettles and open fermenters (and most bottle condition) which are no-no's in LODO. I preferred my Belgians (and I really like my Belgian beers) non LODO (but again, have benefitted from the LODO cold side). My favourite hefeweizen is brewed locally (moobrew) - it's a fantastic representation with a nice banana and clove balance that keeps some mouthfeel (too many are thin and tart). Their water is straight from the tap (filtered) which would oxidise the wort immediately.
I like something I recently read in Brew Like a Monk. It's something along the lines of 'close your eyes and think about what you want to brew, think about the taste, the aromas, the sensation when you drink it, then think about how you would make that happen'. Well, for me, LODO is a string to my bow that I could use to achieve some beer qualities if they were qualities that I wanted. Anyone who hasn't tried it shouldn't say it doesn't work, it does. It just that what it does isn't for everyone. And it doesn't make every beer better - it changes them.
