Maybe I should clarify my opinion. My comment about lazy brewing was aimed at the professional brewers who I believe seek the cheaper or easier options. If I go to a restaurant I don't expect the chef to cook my meal in a microwave so why should I accept a commercial brewery cutting corners. This country has some of the finest brewers in the world built not only on tradition but also moving with the times and the better ones will still maintain their own often unique strains. I'm sure the likes of Adnams would not go to the expense of running a lab if they thought buying in dried yeast would produce the same quality beer. With home brewing I will always accept some will be happy with dried yeast especially those just starting up or others with time restraints and good luck to them but I would encourage other brewers to try for themselves to use the most of what is out there be it culturing from bottles, commercial liquid yeast or the best of all getting live yeast from a working brewery. Visit as many brewery's as you can, I have probably visited 25+ since I started brewing 45 years ago both in the UK and Europe, and if you can talk to the head brewer, not always possible, see how much they value their yeast. If you do buy a liquid yeast get the freshest date you can. I buy from the malt miller and on his site he publishes the best by date which is 6 months from manufacture so you can guarantee the viability before you buy. Put the yeast book on your Xmas list. Written in a way anyone can understand, even if I had to read some bits a few times, you will come away realising why it is our most important ingredient. I know I may come across as yeast geek but it is something I am passionate about and my own research, including attending lectures and having conversations with people like Dr, Keith Thomas of Brewlabs probably the leading yeast authority in the UK, has convinced me the quality of the yeast equates to the quality of the finished beer.
