Today we brewed 20 gallons of an English Pale Ale and celebrated St. Patrick’s day weekend with stout and Irish Red. We enjoyed an easy brewing session, a beautiful sunny day in the 60′s, and delicious corned beef and cabbage thanks to Christine.

Brewmaster- Dickie S. (great job on his first time at the helm)

Brewers- Charlie U., Kyle L., Rob S., Tom V.

Grain Bill-

  • 36# Maris Otter
  • 2# 60L crystal (UK)
  • 2# Carapils

Hop Bill-

  • 4 oz East Kent Goldings 5.0% AAU for 60′
  • 2 oz East Kent Goldings 6.3% AAU for 60′
  • 4 oz East Kent Goldings 6.3% AAU for 30′

Mash Schedule-

  • 13 gallons of liquor, strike temp 165F
  • Mash temp 144F, too low, add ~3 gallons hot liquor to raise to 155F
  • Hold for 90′
  • Mash out, add ~4 gallons of liquor to raise to 160F (not much of a mash out)


  • 10 minute recirculate
  • 15 minute run off
  • Sparge with 14 gallons at ~170F (had additional 5 gallons to push through the grains)
  • Collected 24 gallons and shut down runoff


  • Boil 15 minutes, add 6 oz of hops (4 oz @ 5% and 2 oz @ 6.3%)
  • Boil 30 minutes, add 4 oz @ 6.3%
  • Boil 15 minutes, add Irish Moss and cooling coil
  • Boil 15 minutes, shut down
  • Coldbreak ~ 1 hour until racking into primary

Starting Gravity =  1.060. On the top end of the range. A good, strong number. More volume than the Oktoberfest and should have a solid 20 gallons when we go to packaging. Sample was appropriately hoppy and sweet with no off flavors. Looks like another winner.


Strong bubbles in the airlock the morning after brewing. Temps at the bottom range of yeast, 64F.

March 27- Racked the EPA. Gravity = 1.011. Wow, we are brewing some strong beers! ABV calculates to 6.4%. Sample was right on, strong, green, hoppy (but not in American hippy way).

Mark your calenders! Planning and preparations are being made for the Official 2014 AGU Oktoberfest.  This will be the third annual installment of the  Oktoberfest celebration by the UndergrounD. The date has been set for September 27th, 2014. We encourage all who participated last year to join us again this year.

After a long, grueling day the UndergrounD brewed our Oktoberfest Bier yesterday. It sits in primary fermentation right now. We will let it lager over the summer and have it kegged and ready to go for this year’s festivities.  All indicators say this beer will be better than last year’s Oktoberfest Bier that was such a huge hit at the party.

Last year we ran out of beer (pooh pooh on us) and we do not intend to repeat that mistake. We have taken production to another level in anticipation of the people wanting more good beer. We look forward to seeing you all there again.

We will keep the site updated with news and plans. As we get closer to the date we will have more details to pass on. If you have any ideas, suggestions, or want to volunteer please let us know.
