Im looking to brew a Lagunitas clone next weekend and the recipe recommends WYeast 1056, I usually use dry yeast so googled a dry alternative and apparently US05 is exactly the same strain. Sounds good but.... Brewersfriend recipe calculator has 1056 s 75% attenuation and US05 as 81% attenuation. Are they the same yeast? Should I drop the malt bill a little to make up for the extra attenuation? Why does it have extra attenuation? Or is it just that Brewersfriend is wrong - but then which is right, 75 or 81%?
