On Gel:
I brew a lot of light colored(and flavored) lagers. I have 7 lagers on tap right now and 5 are 4 SRM or less. Lager yeast is not as flocculent as ale yeast and will greatly affect the flavor of these beers. The pic I posted above is of a recipe I regularly brew, my house lager.
That was the first time I've gelled it and the difference between it and the non-gelled version is striking--Both in clarity and flavor. It tastes like a commercial, filtered beer and will be gelled from here on.
I've been brewing a series of lagers with the new Mangrove Jack's M84 lager yeast. That stuff is hazier than wheat beer. I didn't gel one batch with it and it's not as clear or clean tasting as one brewed 3 weeks later. Here's the gelled Helles at 36F serving temp 4 weeks from brewday:
