What was meh with the brews/yeast
Good question! Now I had to rack my brains for the details...
I mentioned it a couple of months back but the Baltic Porter I made with CML Hell was tip top, but a Munich Helles and Munich Dunkel I made just weren't satisfactory. In the Helles it just never cleared up, i.e. the yeast never settled out properly. Much harder to see this in the Dunkel of course, but holding it up to the light you could see it had a bit of haze, and it just had a yeasty background note - not full on like a Hefeweizen or Witbier, but it was there and you could taste it.
I like CML, they seem really good guys and I continue buying my hops from them but I've stopped using their yeasts now (Pia was another one, it just kept on going and going, slowly dropping an extra gravity point just when you thought it was done. It drove me up the wall!).
I'm well aware many other brewers have had great success with CML yeasts so if they're happy with the results then more power to them. But personally I'd rather spend a couple of quid more and use something different where I feel I get more consistent, reliable and predictable results (or it could just be pure chance/luck!).
In the case of the Helles I re-made it shortly after with W-34/70 and was much happier with the result, though I still don't think it was as good as my first ever Helles which was fermented with WY2206.
(I've also tried Lallemand Diamond Lager in Mexican Lager which I was also pleased with though I think I've only used that strain once.)
I think there's a lot of truth in the adage that brewers make wort, yeast makes beer. Certainly some of the split batches I've done have been very surprising. I wonder if this is particularly true with pale lagers where you really have very little room to hide, so perhaps yeast selection can have a bigger impact on the result.
Which is not to suggest that I think dry/liquid yeast is better/worse (god forbid we go down that rabbit hole again!). For example, if W-34/70 was terrible it wouldn't be so widely used. But I think as homebrewers if you're searching for that last little extra something then I think it's clear liquid offers wider variety and more choice.
