2 pointsi think the advice is sound. identify your target before you shoot. decide what you want to brew, find a recipe for it online or other, scale it to your batch size with brewing software or do some math. then go get your ingredients and brew it up. many here have brewed with random ingredients before, but that is probably after brewing many batches and kind of know what to expect. you'll probably make better beer. just my free advice.
1 pointI used Centennial 60 min for my bittering and then Hallertau Blanc 15min. Turned out really well using that combo. I've never used Tettnang, so I know nothing on that hops characteristics.
