Description

A07 Flagship is a versatile strain prized by home and craft brewers alike for its tremendously clean character. A07 Flagship performs well at conventional ale temperatures, but can be used in the low 60s to produce remarkably crisp ales. Due to its middle of the road flocculation, filtration or fining is required to achieve a crystal clear beer.

  • Temp: 60-72°F, 16-22°C
  • Flocculation: Med-low
  • Attenuation: 73-77%
  • Cell Count: 200 Billion

White Labs Equivalent: California Ale – WLP001
Wyeast Equivalent: American – WY1056

Usage Instructions:
  • ​Store refrigerated until ready to pitch
  • Shake and kneed pouch to homogenize slurry
  • Sanitize the sealed pouch
  • Open and pitch entire contents into well-aerated wort

Please Note: For best results we Always recommend ordering an Ice Pack with your liquid yeast. Ice Packs can be found below in the "You might Also Need" section.

Trying this and going to compare it with WLP001 out of curiosity
Eric Hansen on Jan 22, 2020
I've heard it's awesome and I'm making a West Coast style Pale Ale that will be dry hopped with a lot of hops :)

Got a fuller and slower fermentation than some more expensive supposedly higher alcohol resistant yeast!

Imperial yeast is the best yeast brand I have found! No need for a starter. No need to smack a day ahead of brewing. Fast stars and fast finish. Flagship is great clean yeast that lets malt and hop flavors stand out!

Seems to have done the trick
I was a little worried cuz the yeast was a bit old. I made a yeast starter since I was trying a DIPA. Woke up the next morning and the wort had blown the air lock off and it was frothing out. Transferred to secondary after two weeks and the gravity seems to be where it's supposed to be. So, I think this yeast is good if it can handle DIPA duties. Won't know for sure for a few weeks.

Fastest Starting Yeast I have used
I made a 2000 ML starter with my yeast because it was a little warm when it arrived. I sat in the fridge for about 4 days before I got a chance to brew. I pitched in in the late afternoon and when I got up the next morning I was amazed at the amount of blow off I had, definitely needed a larger jar or bucket for this one. This was Fastest Starting Yeast I have used!

My new go to yeast!
Talk about bang for your buck. I make large starters and get a number of brews out of one pack. This yeast takes off fast and finishes fast as well.
I usually ferment at 65-66 and get a very clean beer with hops that shine.

Great yeast - Explosive entrance!
I shook up a can of this & opened it! WEAR GLASSES to protect your eyes! It did blow! However, in the beer it was on fire! This product launched against a 1.068 OG & finished out in 8 days at 1.043 FG. Two weeks later I was enjoying a might fine dark porter! I would recommend this product but I caution, it's entrance will be one to remember!
