Every other Wednesday, 6:00 PM; which weeks is unclear. Only one source reports it.

A page on travelboulder.com lists this night, but may not be current.
A local feature article describes this business as a women's cycling apparel shop, cafe, and recovery lounge with daytime-only hours, closing by 3 or 4 PM (checked Aug 15, 2026) [s1]. Those hours make a 6 PM open mic there impossible, and no source connects this business to music or evening events of any kind; this looks like a misattribution.
Both sources give the same night and time, but neither confirms recent activity.
The venue's own homepage currently lists 'open mic' among its regular programming, alongside a family concert, disco brunch, and other events, though without naming a specific day (checked Aug 31, 2026) [s2]. A listing site claims a weekly Tuesday schedule for it [s1]. That specific day and cadence rest on that listing alone.
Weekly on Wednesdays, 7:00 PM. The Venue's Website does not mention it.
The venue's own comprehensive events page does not mention a Wednesday open mic (checked Aug 15, 2026) [s1]. A local venue-listings site does not mention one either [s2]. An open-mic listing site's Boulder-wide page, which lists other venues, does not include this one [s3]. The venue does run a separate Monday poetry series and near-nightly live programming, but no source identifies a Wednesday open mic specifically.
The taproom's own current website confirms a weekly Wednesday bluegrass pick, distinct from its separate curated Friday concert series (checked Aug 15, 2026) [s1]. The specific 5:00 PM start time comes from an earlier source and was not reconfirmed with a fresh source this time.
The venue's own current website confirms an open mic on the first and third Thursday of each month, starting 7:30 PM, distinct from a separate karaoke night here (checked Aug 15, 2026) [s1].
The venue's own ticketing page lists a weekly Monday Open Mic Night with an upcoming instance on Aug 17, 2026, 7:00-9:00 PM, now hosted by Riley J [s1]. An earlier ticketing listing from Jan 19, 2026 names a different host, Steve Koppe [s2]. The host has since changed.
The venue's own ticketing page confirms a monthly Tuesday 'Sober Open Mic,' with a dated instance on Aug 4, 2026, 6:30-8:30 PM [s1]. That matches this listing's schedule exactly. Frequency is now recorded as monthly rather than unspecified.
Night and frequency are unclear — no source gives either. The Venue's Website does not mention it.

The Venue's Website suggests it may have ended.
The Venue's Website, checked cleanly Aug 15, 2026, does not mention an open mic [s1]. The only source describing a specific schedule (an 8-11 PM window matching the schedule listed here) is an old newspaper article from a publication that stopped operating in 2022 and appears older still. A social-media post title hints the event may still happen, but that could not be verified.
Thursdays, 6:30 PM. How often is unclear. The Venue's Website does not mention it.
Call to confirm the night
The sources disagree about whether it still runs.
A dated local news article confirms this venue opened in April 2026 [s1]. The venue's own saloon page makes no mention of an open mic (checked Aug 15, 2026) [s2]. Its homepage, menu page, and a civic listing were checked too, with no mention found on any of them. The only support is a listing site entry.
The venue's own events page confirms a monthly open mic, 'The BLOOM Open Mic Night,' on the last Tuesday of the month, with dates listed through December 2026 (checked Aug 25, 2026) [s1]. An earlier check had missed this because it only looked at the homepage, not the dedicated events page.
