I recently finished brewing a Belgian Witbier and now that the fermentation is complete I have decided to harvest the yeast cake that remained. I was actually considering taking this harvested yeast and placing it in with my Dubbel that has been aging for about 2 months now in a secondary. It is still bubbling pretty crazy after all this time and was wondering if it would be okay to experiment by placing the harvested Belgian Wit yeast in with the Dubbel. I know that generally you should use a similar yeast strain to the beer you are brewing, but thought since they are both Belgian style beers it might not be a big deal. I am welcome to any comments or alternative suggestions.
