From one of the best examples of an east coast IPA.

From one of the most famous stouts in the world. Creates a crisp, dry beer with a subtle fruity profile and a slightly tangy finish.

A01 House

The best of both worlds, House is clean and allows malt and hops to shine. This strain is extremely versatile and flocculent enough to drop out of the beer quickly. Best used in American IPAs but works well in English style ales. House is clean at cold temperatures with increased esters as fermentation temperatures increase.

  • Medium: Liquid

Imperial Yeast

A04 Barbarian

Ready to attack your IPA, Barbarian produces stone fruit esters that work great when paired with citrus hops. Barbarian will give you what you need for an exceptionally balanced IPA.

  • Medium: Liquid

Imperial Yeast

A07 Flagship

A craft brewing standard, Flagship is a versatile strain loved for its extremely clean character. This strain performs well at standard ale temperatures, but can be used in the low 60s to produce exceptionally crisp ales. Flocculation is in the middle of the road and will typically require filtration or fining to achieve crystal clear beers.

  • Medium: Liquid

Imperial Yeast

A09 Pub

Brewers swear by this strain to achieve super bright ales in a short amount of time. One of the most flocculent brewer’s strains around, Pub will rip through fermentation and then drop out of the beer quickly. Pub produces higher levels of esters than most domestic ale strains. Be sure to give beers made with Pub a sufficient diacetyl rest.

Imperial Yeast

A10 Darkness

A beautiful strain for stout, porter, brown, and amber ales. Darkness produces a unique character that matches up perfectly with roasted and caramel malts. This strain is alcohol tolerant, so don’t hesitate to throw high gravity worts its way.

  • Medium: Liquid

Imperial Yeast

A15 Independence

Independence is the strain for bringing some new character into your hop-driven beers. Higher in esters than Flagship, this yeast will give some fruit character that will take your hoppy beers to a new level. While it shines in pale ales and IPAs, Independence is a great all-around strain and will also work well in stouts and English ales.

  • Medium: Liquid

Imperial Yeast

A18 Joystick

This strain is a fast mover and can be used at the low end of the ale fermentation spectrum to keep it clean. Joystick is a good choice for big, high alcohol, malty beers but has no issues chomping on a hoppy double IPA.

  • Medium: Liquid

Imperial Yeast

A20 Citrus

Citrus cranks out orange and lemon aromas along with some tropical fruit. Use this strain at high temps for big ester production. A wild saccharomyces strain, it will get a bit funky without the worries of a brettanomyces strain.

  • Medium: Liquid

Imperial Yeast

A24 Dry Hop

Dry Hop is a blend of A20 Citrus and A04 Barbarian.  When this blend goes to work on your hoppy beer, the hop aroma blows up.  The combination of these strains produces amazing aromas of citrus, peach and apricot that will accentuate your IPA, pale ale, and any other hop driven beer.

  • Medium: Liquid

Imperial Yeast

A31 Tartan

Tartan is a traditional strain that accentuates the malt character of Scottish ales.  It can also be used for other styles and works well in IPAs due to its clean character.  For a higher ester profile, use this ale yeast at the top end of the temperature range.

  • Medium: Liquid

Imperial Yeast

A38 Juice

Juicy. Fruity. Juice is an amazing strain for East Coast IPAs. The ester profile of Juice brings out the aromas and flavors of the new school hops and creates a beers  that is greater than the sum of its parts. Keep an eye on this strain, it likes to move to the top of fermentation and will climb out the the fermenter if too full.
