Lessons in Hops, IBUs, & Scheduling

Ahtanum (hop), a hop cultivar grown originally by the Yakima Chief Ranches. Ahtanum is reported to be an open-pollination cross among Brewer's Gold, Fuggle, East Kent Golding, and Bavarian aroma hops. The variety's name is derived from early Yakima Valley hop history when Charles Carpenter brought hop rhizomes to the area and grew them on his homestead at Ahtanum, now a small community west of Yakima. The cultivar has never been popular with large breweries. Thus, acreage is low. It has been favored, however, by many craft breweries. Ahtanum has an alpha acid range of 5.7% to 6.3%, a beta acid range of 5% to 6.5%, and a cohumulone range of 30% to 35%. Its aroma profile is floral, citrus, and piney, with grassy notes. Similar to Cascade, Centennial, and to a lesser extent, Amarillo. - Matthew Brynildson. The Oxford Companion to Beer. 2012

Pallidus Ahtanum

The Pallidus Single Hop Experiment brews on. 37.6 IBUs. OG: 1.058. 77% efficiency. The two ounce hop restriction affected by packaging and the finance department only effects the brewing on very low alpha acid hops. This is one of them. I don't think there will be another this low.

Sad Carboys

So sad. Empty carboys. One has been filled.

A very smooth and cool autumnal brewday.

Dear Professor Hamachi,

Out of the 700 bottle caps you have recently received, I would like to kindly request that you set aside 20 of the very nicest ones for me.

I would like to make earrings out of some of them.

With the others, I will cast hexes.

Much appreciation in advance,


PS: Thank you for inspiring me to learn about new things like hops and stuff.
