Hey everyone, this is my first post and preparing for my first brew. Iv'e been reading John Palmer's "how to brew". I bought a kit from brewers best for a Dortmunder style beer. Anyone tried this one? My first concern is that i dont think im really set up to do this as a lager, it does have directions to brew it as an ale, but wonder how much of difference in taste that i will be sacraficing when i brew it as an ale. Second, the kit includes a package of dry lagar yeast "Saflager W-34/70" it appears to have an expiration date on the bottom, "07 2010". It appears to be expired, should i be concerned?
