WLP001 California Ale Yeast – PurePitch Next Generation 70 ml
WLP001 California Ale Yeast was the first yeast strain White Labs produced, in 1995, and is known for clean flavours and vigorous fermentations. It is popular in hoppy beers because it lets hop flavour and aroma shine through, and it attenuates well even in high-gravity beers. The strain can be used in almost any beer style, from IPA to porter and even kölsch.
Please note: This product is only available in Norway.

PurePitch Next Generation contains twice as much yeast in a 70 ml pack, giving 7.5 million cells/ml. That is the recommended amount for 20 litres of standard ale with an OG below 1.074 and a temperature above 16 °C, so you do not need a yeast starter. Just twist off the top and pitch the yeast.
