Well, we're back and it's Yeast Vs Yeast time again.
This time we pitted WHC Banana Split up against the Mangrove Jack's M20 to see which will give us the best outcome in tasty German wheat beer.

Comments:
This style of beer is all about freshness and drinking whilst young. Youll want to enjoy on a warm late summer evening with friends and drink it whilst at its freshest. The balance of flavour and aroma is vital and the yeast used will be key to this. Fermenting on the cooler side of this yeasts capability will promote clove esters and moving to the warmer side of the scale will promote banana to show up. You can choose where you want this to sit but we prefer the clove profile, hence the fermentation temperature being lower.
