For the past two weeks I have been doing an experiment regarding my brewing prowess.

You see, my neighbor at the end of the block asked me to both roast a pig and brew beer for the upcoming Memorial Day party, a challenge I gleefully accepted. The pig, no problem. But the beer.... another issue.

You see, he's a BMC guy, as will be the greater part of the partygoers, and he wants a 1/2 keg. Something to please the non-enlightened beer drinker, no problem. I've got a few recipes. But, the 1/2 keg, that's 15.5 gallons. I am limited to 5 gallon batches, so that means I have to do it as 3 seperate batches to get 15 gal.

That's where it gets interesting; three batches of the same recipe, brewed a week apart and served together the same night. This is where a brewer's mettle is tested, how consistient will they be? They should be nearly identical, with some leeway given to the difference in age between the first and last batch.

I decided to go with my blonde ale recipe. It's my lightest both in terms of color and flavor.

Carbonation and Storage

Keg/Bottling Temperature: 45.0 F Age for: 14.0 days
Storage Temperature: 45.0 F


So far, I have the first 2 brewed, and I'm about to start batch 3 as we speak. Batch 1 just got racked to clear up. Batch 1 was a degree off in the mash, 153*f, batch 2 was on at 152*f. I'm wondering if that slight difference in temperature will make a noticeable impact.

So that's what I'm up against. My brewing prowess will be put to the test. Can I brew the same recipe three times with the consistiency expected from the pro's?

Time will tell my brothers and sisters, time will tell...

You are a brewer, your friends ar BMC drinkers. There is nothing to prove.

Your pig will taste great, Their pig will taste like water......anything after that is your beer, and they just won't "get it" any way ;)

You should definitely try to have something there you like as well (or something else you like anyway). Might just convert some people who have never tried the real stuff:mug: More craft beer drinkers supporting craft breweries is a good thing. We are the Mormons of the beer world:D

Oh, I'm going to have a bunch of 2 liters in my personal cooler. I'm bringing the oatmeal stout, irish red, amber and ESB for personal cunsumption and sampling.

The experiment is more for my interest. The party is just the excuse to do it. I think it'll help me fine tune my process a little.

Are you trying to fill one 15 gallon keg? or just have 15 gallons available to drink? Variety is the spice of life - I'd give them 3 different tastes & see which one they go for.

How will you be serving this beer? Bottles? Kegged?

I probably would have used different strains of yeast to see the difference between them.

This is kegged in cornies. The other reason I'm going with this recipe is cost. It's my cheapest recipe. Since I'm donating the beer to the party, I'm using it as an excuse to test my process, hence repeating the same recipe.
