Enhancing clove and banana character?
Why on earth would you want to do that? I can't stand cloves in a beer, roasted pork shoulder, yes, beer no.
That being said, when I first started brewing almost two and a half years ago, I went through this phase of brewing every style I could think of. I brewed a Dunkelweizen, knowing full well that I hate cloves in a beer
, and used White Labs WLP351 Bavarian Weizen Yeast. I made a starter with it and it had significant cloves and banana characteristics. I would give this one a try if that's what you're going for.
Everyone's taste buds are different and YOU should definitely enjoy the beer you are brewing. Hope this helps...
