Hazy Yeast Battle: Verdant IPA vs SafAle S-04

Verdant IPA yeast from Lallemand is a variant of London III from Verdant Brewing in the UK. SafAle S-04 is the old standby for many homebrewers and some commercial breweries. Both have a clean and dry but malty English profile.

For this comparison I brewed a double batch of a Hazy Session IPA - you won't find the style in the BJCP list - I actually used British Golden as a framework for the recipe. 

RESULTS: I rushed these through fermentation, dry-hopping, cold crash, and kegging in less than a week. The Verdant batch was fine with that. S-04 needed to be pulled for a couple of days for diacetyl rest - it had a tinge of butterscotch that went away after the time outside the keezer. Before resting the S-04 it was obvious and I could tell the difference between these beers. After the rest I tried a triangle test and could not tell them apart. For a hazy I'd feel comfortable with either yeast; just be sure to give S-04 a couple of extra days and don't try to keg too soon. 

The full recipe is on BrewersFriend but here's the TL;DR:

  • 2020-10-31: brewday
  • Malts: Maris Otter, Munich, Flaked oats
  • Hops: [Centennial] (Mosaic, Citra, El Dorado) {Galaxy}
  • Yeasts: Lallemand Verdant OR SafAle S-04
  • OG: 11°P; FG: 2.5°P; ABV: 4.5%
  • 2020-11-7: kegged
grains with about 10% flaked oats 

Nothing fancy here - got these on sale at King Soopers

Brew session beer: Barmen Pils comes in cans now (if you're in CO)!

Lots of hops

early and late boil additions - the late hops were only in for 2 minutes before chilling; but it's still more bitter than I wanted. Next time I'll move the late addition to a hop stand.

Fresh pitch of each yeast

Kegged samples - looking and smelling nice!

They look exactly the same so it doesn't matter which one this is. But here's a full pour.
