When the website was checked, they claim the Diamond yeast is appropriate for many lager styles, including Czech Pilsner.
Being a German yeast, is this a good yeast for a Czech beer? I really like how ours turned out. As good as anything we had in the Czech Republic.
Get this...I got up at 4am yesterday, for a big day of brewing. The harvested Diamond had been sitting on the kitchen countertop since midnight, warming to room temp. A one quart starter was then added to the yeast, and I went to the office to check my email...while drinking a cup of double-shot espresso coffee Americana. Before my coffee was finished, I went back to the kitchen to get some things ready. I noticed a huge puddle of foamy looking liquid, all over the counter, running down the cabinets and going onto the floor. This all happened in less than 10 minutes!!!
That yeast is hyper-potent! I won't make this mistake again.
