Micheal Shea's Black and Tan

[fuji6100]

I found a clone recipie for one of my favorite beers (that no longer ships to this area) in a book i just bought. It is for Micheal Shea's Black and tan (a porter & lager)

Anyway, the book recommends brewing a 2 3/4 gallon lager 2 weeks ahead of time, then starting a 2 3/4 gallon porter. Once hte porter has finished primary fermentation, you rack them both into your 5 gallon secondary and let it finish out in there for a week or two.

Anybody else have any experience doing something similar? I wonder how the lager and ale yeasts will interact once combined.

That is an interesting question. So, when you rack them both into the secondary, are you supposed to cold condition it for those couple of weeks or leave it at ferm temp? I've never had the beer (O'Sheas) so I do not know what it should taste like.

The combination of lager and ale yeast will be fine there are many styles of beer that use a combination (ex Cream Ales).

I am guessing here, but I would think you would need to condition at the ale temperature, or risk creating hand grenades due to the ale yeast going dormant due to the cooler temperature.

Any fruitiness associated with the lager yeast finishing at a higher temperature should be offset or masked by the stronger flavour of the porter, and the high hops used in it’s making.

I have never heard of a porter used to make a black and tan, it has always been a stout and lager or pale ale. Sounds like a good beer!
