Flora Fermentation releases fifth Siren West Coast IPA
Flora Fermentation, based in Higashiomi, Shiga, has released Siren, a West Coast IPA now in its fifth outing. This batch uses a slightly heavier dry hop of Riwaka Diesel, aiming for bright fruit notes, pine-like aromas, and a clean bitter finish.
Hop BroToday’s big beer topic is batch five of Siren from Flora Fermentation in Higashiomi, Shiga. It sounds like a seriously sharp West Coast IPA.
MugiWait, the name Siren already sounds dangerous! What kind of beer is it?
Hop BroIt’s 6.5% ABV and 40 IBU, with classic West Coast character: fruity aroma, pine notes, and a clean, firm bitterness.
MugiHold on, what does 40 IBU mean? You can’t say that like everyone grew up inside a brewery!
Hop BroIBU is a bitterness scale, and 40 usually means solid bitterness without getting too heavy, basically crisp but properly bitter in the best way.
MugiOhhh! And the article said extra dry hopping this time. Did the hops go through some kind of Rocky training montage?
Hop BroThat would be excellent. Dry hopping means adding hops after fermentation for aroma, and this batch used more Riwaka Diesel for fruit-and-pine aroma that really pops.
MugiOkay but Riwaka Diesel sounds like a final boss. What kind of hop is that, exactly?
Hop BroIt’s a late-picked New Zealand Riwaka meant to push riper hop aromatics. With Citra, Cascade, and Chinook, it gives sharply defined hops all the way through.
MugiAnd Flora Fermentation grows some of its own ingredients too, right? That makes it feel like farm-to-ferment flavor instead of just another IPA.
Hop BroExactly. The name comes from the Greek Siren too, and the whole idea is an IPA that makes you want another sip immediately. I’m already craving one.
MugiSame here! If I spot a can, I’m grabbing it fast and calling for a Siren toast on the spot!
Siren returns for a fifth release
Flora Fermentation, based in Higashiomi, Shiga, has released 'Siren', a West Coast IPA. This is the beer's fifth release. The new batch comes in at 6.5% ABV and 40 IBU, with batch number 99/100. The hop bill includes Cascade (NZ), Riwaka Diesel, Citra, Cascade from Kamifurano, and Chinook, and this version is dry-hopped with a little more Riwaka Diesel than the previous batch.
Riwaka Diesel is described as a late-harvest Riwaka hop from New Zealand. Compared with standard Riwaka, which is known for tropical fruit, lemon, and grapefruit character, the later harvest is said to draw out a riper hop aroma. Flora uses that character to shape Siren into a West Coast IPA with passion fruit, grapefruit, and pine-like aromatics, firm bitterness, and a clean finish.
The name 'Siren' references the sirens of Greek mythology, whose songs lured sailors. In that sense, the beer is designed as a hop-forward IPA that invites another sip after the first one.
Flora Fermentation describes itself on its official site as a brewery that makes beer through agriculture and fermentation. The brewery also emphasizes growing hops and barley itself, which makes Siren fit neatly into its broader approach: a beer that highlights the character of the raw ingredients rather than hiding them.
Cans are listed as available through the August 17 shipment, and stock should be checked with each retailer.
