Excellent write up and fun experiment!

Send me one of each with non-descriptive labels and I'll try to pick out any differences. (Really, I wish I had enough tasting experience to make a serious lab-rat offer)

*subscribed* :mug:

Keep us posted as they mature!
 
Just to note my pale ale's (or Strong English Bitters) will need some more time and wont be ready when J's batches are done. I started a little bit later, and although are only going to be around 4.5% abv and shouldn't need too long of a conditioning, don't want to rush them too soon.

I'll post pictures soon of the process.
 
This is a great post. It makes me want to build an electro-mechanical device that auto drops individual pellets over a specified time interval. Count up the hop pellets, divide by 60, program the drop interval, then sit back and have a few beers while geekishly watching the pellets drop on by one......hmmmmmm.

Great read.. Time to get out the old erector set haha...

I just ordered 15oz of hops last Saturday, gearing up to brew the 120IIPA again, a machine to dump for me would be pretty sweet :D Thinking about it though I would miss my "3 pointer" hop additions from across the kitchen around addition 35-36 once the beers from the past hour and a half are starting to really kick in heh..
 
That's awesome bwomp313...thanks for the link :mug:

When I talked to some people about the experiment I was participating in they were all saying, "yeah, Dogfish Head does that with some beers". But I was trying to explain that it wasn't about the continuous hopping part being the experiment, it was to see if there was a distinguishable difference between continuously hopping and not.
 
Clever, kind of like a case study on yourself and each other.

Man do I feel dumb.... I forgot again your wife can't drink yet :drunk:

Just disregard that part of the post and that part of the message lol

I would say you have to do that 120 min double IPA!!! For the grand finally we should all drink it out of 'Das Boot' as well :rockin:

Had one before? They are deadly. My first batch got close but I didn't break 21%. My buddy drank a couple at a pool party this last summer after already having a couple beers beforehand (dumb move obviously), anyhow renamed it 120 IRPA (R for roofie) the next day as he blacked out and couldn't remember a thing :tank:

I'm switching it up this time though as well, I opted to use Centennial hops instead of Warrior and I'm adding more of everything to make up for and surpas the original bitterness ratio of the clone recipe (anyone that has brewed it comes back saying the same thing - I wish I would have added more hops), I'm also trying to land it around 15-16% and let it finish dry in oppose to the mid+ 20s, it gets pretty syrupy if you let it fade from cold to chilled / slight room temp.
 
A note to anyone tagging along with the topic - all beers to participants have arrived, from the sounds of it we're all taste testing this weekend, experiment results should be in next week!

Cheers!
 
Just popped open one now! Not gonna post any feedback yet.. but just thought I would share a link. I've never really graded a beer before and actually a little nervous lol so wanted to find a little reference that might help.

Tasting Beer

(if anyone wants to not essential)

Prost!
 
I found with my continuously hopped beers the aroma is actually lacking. So Dry Hopping is very necessary as is adding hops to the keg. Also note, I used leaf hops for everything.

My IIPA is 9.2%abv with 85 IBUs
6 oz's of Amarillo were used during the boil
1 oz was dry hopped in fermenter for 4 days
2 oz added to keg.

Initial taste tests were a favorable but were lacking the aroma punch.
 
Just read through the thread, very interesting and relevant. Before even seeing this i was debating continuous vers intervals for my next IPA. I have done both before, but i did to many different things with the beers to get a good comparison. So im very much looking forward to the results.

Wow that sounds good. Makes me want to brew a batch of a IIPA now. That seems odd that with all those late hop additions the aroma wouldn't be more pronounced. Maybe the strong presence of the malt covered the nose of it??
 
Cool thread!! I just brewed my first batch of beer last weekend, a brewers best ipa kit. Instead of following the directions and pitching all my bittering hops (cascade and columbus) during the first 5 minutes of boil I spread it out and pitched every ten minutes breaking the hops up into 5 equal portions. I then added my aroma hops (cascade I believe, not sure but it was the same as one of the bittering that came with the kit) at the last 5 minutes of boil. I just switched over into a secondary and am dry hopping 1 oz of citra hops hoping for a real hoppy bitter beer. Can't wait to try it. Anyway i did this due to the fact i wanted to see how hopping at various points would benefit rather than throwing all my hops in at one time and letting them brew down. I am loving the info I get here on this forum!! Cant wait to brew my next batch and try some more "expirements"!!
 
Well - Good things and bad things from this weekend, the Cascade IPAs were okay however the Amarillo IIPAs didn't carbonate and really tasted awful, enough that I ended up dumping my 2 cold Imperial test beers - planning to leave the rest sit for a couple of months. It was a lesson well learned on paying attention to measurements because those 2 Amarillo's were by far the worst things to have came out of my brewpot.

The Cascade's though not extremely carbonated were better, and drinkable - still not a prized beverage but good enough for the test. I'm already showing interesting results from my end, I put 1 more of each in the fridge yesterday and plan on having a second go at taste testing this week, maybe on Turkey day after everything is done and over with.

It was the temp that I taste tested at I think. Either way I'm going for a punch you in the face type of aroma. I think I have it nailed dead now. I think in a few more days we'll be really enjoying it.
 
Yesterday I brewed my second beer in the Single Hop Series. Same Grain Bill.

20lbs 2-row
1lb 10L
.5lb Special B
6oz's Chinook Leaf hops

1200ml Starter with a blend of WLP099 and ECY10(Old Newark Ale). Should be done by next week.
 
Hey J, I think I might of graded the 'Alcohol Presence' wrong. Should it of been lower the value the more alcohol taste detected? I probably should of had clarity on that before the chart test. Also, I graded the clarity and color by it's style on which SRM it should be (like double IPA's shouldn't be completely transparent lol).

I drank those last two beers anyway, had all six Friday night. I didn't think they were too bad considering the carbonation, although had a pretty good buzz on from the single and double IPA's lol

I really like the 'Special B' sounds like you might be going for a British style with a Belgian twist? Are you going to use Marris Otter for the 2 row?

Yeah dude! That is a pretty bold IPA, get ready for a real blast of hops with citra. I love them dryhopped, you can even reuse that ounce for your next batch for bittering if you want. They are a pretty strong alpha acid hop, I think I read they loose about 20% through dryhopping but all considering that is a really strong hop!
 
get ready for a real blast of hops with citra

+1

LHBS called me yesterday, I thought my 120 hops were in, turns out they hadn't even shipped yet because they have the Simcoe and Centennial but Amarillo is on back order. I'm hell bent on using those 3 hops so I think for now I'm going to try and find a couple ounces of Citra and just do a simple SMaSH. I tried a citra centered IPA from Scottland a couple weeks ago, it blew my mind! Grapefruit bomb!
 
bummer, but yeah I'm a huge Citra fan!! When I think of that hop I think of summertime, once the snow starts falling I'm gonna really want a pint of one, me thinks.

My pale ale should be done in a week, week and a halfs time. I'm thinking just use your same rubric, are you going to post results this thread or make another?

Maybe I'll do a 120 min IPA too. After getting a taste of those IPA's kinda want to make a 5 gal batch of one not just for experimenting but general consumption.. heh. Maybe have a friendly competition with one or something?
 
Nah, actually thinking about it I'm going to do a IIPA debating continuously hopped or not. Never done a IIPA before and now after reading others and tasting your brews really got my mouth watering to make a 5 gal batch. I'll send out a few bottles to some folks when its done.
 
The 120 is a great experience to brew but you definitely have to have an open schedule - it takes a lot of attention. I'd be very open to simultaneously brewing it and swapping, I've swapped more 120s on this forum than any other beer. Tell you though, I'm sticking to my guns and my altered recipe. The original chef recipe is spot on but it's beast. Way more hops, 15%abv, lower fg - I'm extremely confident my second round will be better than the first.

As for results, waiting for a pm from the last participant then I'll post them here.
 
All results are in......... except for my own! I can't figure out where the @!#$ I put my results, I think SWMBO may have pitched them while cleaning the other day. I threw a couple more Cascade + / - beers into the fridge, I'm planning on drinking them tonight or tomorrow THEN we'll be complete and I'll have the final numbers.

Here's to getting drunk and misplacing valuable information :tank:
 
After long wait, all results are in and the scores have been calculated...

A quick summary if you're stumbling on to this topic for the first time, I questioned a while back whether or not the continuous hop methods of DFH really brought a more well balanced beer to the table showcasing the hops, or if in a blind test Joe-Beerdrinker (aka me) would even find a noticeable difference. With suggestions from members of the topic, I brewed up 2 gallons of a Cascade IPA, mirror image recipies, 1 gallon was hopped once every 3 minutes for 60 minutes, the other had 2 additions, one early, one late.

Each batch was bottled then blindly labeled so nobody but my better half currently knows which beer was continuously hopped and which was double hopped, the differentiating label on each cap was a plus or minus - she is the only one with the key. I shipped samples of each to 2 HBT members, I took a couple of beers over to my buddy Dave's house, and we all sampled the beers using an identical grading scale for results.

That brings us to today.

First off, an explanation of how we judged the beers: Each participant used a scale of 1-4 in each proposed category which were as follows:

Ratings:
1 = mild / below average
2 = moderate / average
3 = strong / above average
4 = EXTREME / AWESOME


Categories:
Clarity
Nose
Body
Bitterness
Hop Flavor
Malt Flavor
Alcohol Presence


On that note, let's take a look at the results in comparison:
BREW_FINALS.jpg


The overall winner unanimously in the tasting experiment was the Cascade IPA -.

Though my buddy D-Leu scored the CIPA+ 2 points higher in the end (the only one to do so), he overall appreciated and enjoyed the CIPA- more. When asked how that's possible with his numbers against him, he explained that bitterness is not a good factor with his pallet though he loves the presence of hops - his ideal IPA being low bitterness, high hop aroma and flavor therefore his bitterness score should count AGAINST his overall number, which ties his numbers at 12/12 if you subtract bitterness.

The first thing that really pops here is the unanimous decision that CIPA- was a better beer, not just by numbers, but by tasting notes from each participant. All 5 of us (Bwomp313 tasted his beers with a friend) stated in our notes that overall the minus was a much more balanced and enjoyable beer - the only one who didn't come right out and say it was Brew4it which comparing his notes to each, CIPA- was clearly his favored of the 2 (please comment and correct me if I'm wrong B4it). So 5 out of 5 drinkers agree on the win, interesting non-coincidental results and good data!

Let's analyze the numbers and bring out some taster notes - I will compare everything however anything that takes a loss by a single digit can fairly be dismissed as too close to call - not enough separation to truly assume there was a noticeable difference.

Clarity: CIPA- wins by 2 points ~ clearly (ba dum tzz :D) the better looking and clearer beer of the 2. No additional notes were given on this category.

Nose: CIPA- wins by 1 point ~ This is close but the notes were interesting, Bwomp313 noted neither beer really came forth with a heavy hop front which illustrates the benefits of dry hopping an IPA, however felt CIPA+ was slightly more complex. B4it noted good hop scents on the CIPA- however noted the hops though slightly present were masked by the malt of CIPA+. I noted each had a good malt aroma with very light hop presence though I appreciated the overall scent of CIPA- more in the end. D-Leu was pleased with each.

Body: CIPA+ wins by 1 point ~ I myself noticed no difference in the body of each beer, they each felt identical to myself, Bwomp, and B4it. D-Leu noted a slightly lighter body with the CIPA- however 4 out of 5 tasters seeing no difference, this win is irrelevant.

Bitterness: CIPA- wins by 2 points ~ I felt CIPA- was a bit more on the bitter side however that was matched by the nose and hops so it really came acrossed balanced to me. Ironically D-Leu was the only taster out of us that noted less bitterness with CIPA- in his numbers but didn't give any comments on it. Bwomp and B4it also showed bitterness differences between the beers, no notes from Bwomp, B4it noted a more up front bitterness with CIPA+ and though he scored higher bitterness for the CIPA- this was masked by the hop malt balance of the beer, no additional notes were given.

Hop Flavor: CIPA- wins by 3 points ~ Now here are some goooood numbers. Clearly the most different feature of each beer. I didn't really notice anything to different about the 2 accept that I could better define the hops profile from CIPA- but I felt it wasn't enough to bump the score up. All other tasters unanimously felt that the hops were more upfront and present in CIPA-. Bwomp noticed hardly any difference noting he did get more fruit from CIPA-, B4it noted CIPA+ may have been masked by the malt but the balance of CIPA- definitely brought forward the hop profile, D-Leu noted he liked the fact the hops were more present with the bitterness masked which is interesting when looking at the other tasting notes, perhaps it was the balance of the beer that masked the bitterness from his pallet giving a all together better drinking experience.

Malt Flavor: CIPA+ wins by 1 point ~ This is an interesting category, a split decision if you will. I tasted nothing really different, D-Leu caught less in the CIPA-, Bwomp caught less in the CIPA+, and B4it caught less in the CIPA-. More than one brewer noted more sweetness from the CIPA+ however we all clearly noted a solid presence. Close call here.

Alcohol Presence: CIPA- wins by 1 point ~ Nobody likes to smell rocket fuel and I was pleased that 4 out of 5 tasters saw no difference between the 2 beers, 3 of us noting a low score presence of 1. B4it caught more alcohol taste and scent with the CIPA-, the deciding factor in the category - looking at his scores it's apparent that less malt body led to more hop aroma yet unmasked a little more scent of alcohol. Being though 2 is the highest number here, both beers are winners in this category to me showing hardly no noticeable differences between the tasters.

And there you have it. The results of this taste testing experiment, Cascade IPA - is the winner by unanimous decision.

BEFORE I SPILL THE BEANS AND POST THE KEY....... Participants, tasters, topic followers, drifting forum readers, I'm curious after looking at the charts and reading the result comparison notes, please tell me the following:

Which beer do YOU think is the Continuously Hopped Cascade IPA, and which beer is the Double Hopped Cascade IPA?

I will post the key tonight when I get home from work.

Cheers!
