This is an excellent recipe. I’ve done versions of it in the past and end up tweaking it each time but this would be the version I stick with from now on. Deeply malty. Some good caramel raisiny flavors. I like my doppelbocks to have some roastiness to them to counter the sweetness a little and the chocolate malt does that nicely here. You have to do a docoction mash with this, it’s the only way this recipe comes out.
