  1. Juanita

    I was a little worried about what I would use to cover my oak barrel when I stumbled across this cap. It perfectly fits the barrel 5 gallon barrel and has a weave tight-enough where I am not worried about bugs or dust in the brew.

  2. Jackie H. (Oregon)

    I LOVE the brewer t’s, they work great to keep out bugs and dust and look cool too! This one fits perfectly on the oak barrel. I like that it allows the brew to "breathe" while protecting it.

  3. Mike Shick (Paso Robles, CA)

    Beautiful.  I have the black.  It looks sharp.  It does the job.  Will buy more when this one doesn’t work.  Thanks!

  4. Michael

    Fits just right for the oak barrel. Nice and tight to keep the bugs out.

  5. Sherry

    I have been running my barrel for a few months and these covers work. I have two so one is always clean. Looks great
    Works great

  6. Jennifer (Roseville, CA)

    I received this brew cap complimentary with my oak barrel. It fits perfectly and the elastic seems nice and strong so that it won’t wear out over time. I appreciate that it is made by KK and not imported in from some far off place!

  7. Diana (BC, Canada)

    Perfect fit and really does keep fruit flies out. The camel color blends in nicely with the barrel colour but I also ordered a black one too for a fun change.

  8. Lily Shanks

    I just had to have 2 more of these covers. They’ve kept the fruit flies out and their just so easy to cover with.

  9. Jeanne

    My camel cover looks perfect on my beautiful oak barrel.

  10. Robin

    I am very happy with the cover that came with my barrel. It has a very tight fit & keeps those pesky fruit flies away from my brew! The camel color blends in nicely with the barrel color.
