The new beer unveiled by Beer Cafe Vertere is "Frustum," a Hazy IPA created in collaboration with Ise Kadoya Beer. According to the post, the specs are ALC 6.5% / IBU 13, and both breweries used yeast different from their usual selections, while also combining Strata hops from different lots in the recipe design.

The flavor profile is described as mango, pineapple, ripe berries, and a subtle creaminess. It is said to have a soft mouthfeel from oats and wheat, with a silky texture, while still finishing clean. The goal seems to have been to balance the thickness expected of a Hazy with a well-rounded finish.

The release is 12:00 on March 6, 2026. Alongside it, the "ISEKADO Collaboration Pack" was also announced, with the following contents:

- Frustum / Hazy IPA ×2 bottles
- Efulensia / IPA ×1 bottle
- Casimiroa / NEIPA ×1 bottle

Based in Okutama, Tokyo, Vertere is a brewery that, according to its official information, focuses on creating beer experiences with an emphasis on "who you drink with, where you drink, and how you drink." This collaboration can be seen as a release that concretely expresses that philosophy through the recipe itself. Rather than being a one-off publicity move, it turns differences in yeast and hop lots into flavor, making the comparison experience more interesting for drinkers.

For anyone looking for an angle a little different from the standard Hazy IPA, or for those who want to follow a design philosophy that only appears in collaborations, this is a release worth noting.
