Yet Another Yeast Experiment

UPDATE: Two years between updates?!? Well, it's more like 19 months.  Anyway, we recently had another tasting and the results are up!

So there we were with 3 gallons of honey, 12 single gallon jugs and a weekend to spare. Thus, was the Great Sunnyvale Yeast Experiment of 2004 born! Okay, that's not exactly how it happened. We actually planned it out ahead of time, ordered some honey and jugs, and built a wooden box that wouldn't look out of place in a medieval dungeon. Okay, the box is only used to store tools (hey, that's where my belt sander got to) but we had to do something while we planned, right?

The plan was simple: Start 12 single gallon batches of mead from 12 different yeasts and drink liberally. The recipe is as follows:

2.5 Gallons Orange Blossom Honey
44 Litres Water
4 Tea Spoons Yeast Nutrients
4 Teo Spoons Yeast Energizer

Sorry for mixing metric and imperial units there. Also, the nutrients and energizer are news to me. I don't remember actually adding them, but there they are in the recipe. I do have an open bag, so I guess we added them. Who knew? Well I do know that no heat was used because it was a royal pain getting the honey to pour. The water was generic Albertson's store brand "mountain spring" water in the big 2.5 G containers.

The must was doled out mostly evenly into 12 jugs and shaken like the dickens. Then the yeasts were activated in clean plastic disposable bowls (except the White Labs liquid yeast). After the must as inoculated, they were plugged with an airlock (with a wee bit of vodka) and dropped in a huge freezer. This was 27 March, 2004.

The compressor on the freezer is out, but I hacked a smaller cooling unit into the top. It works quite well, but can't win when the external temperature is over 30C (about 85F). On warm days I would drop in a block of ice and the temperature would stay cool inside. While the temperature range would vary between 18C (65ish F) and 23C (72F, I think), all of the bottles were essential at the same temperature all the time. One day the temperature peaked at 26C because the plug fell out of the 12V adapter, but fermentation was well finished by then.

The meads were racked propty after they finished... No wait, that's not true. Once they fiished, we talked about racking them the next weekend. We were busy then so we aimed for the weekend after that. Except I wanted to go fly that weekend, so it was definatly the third week of sitting on the lees. But that weekend was some family thing for my co-conspirator so it was out too. Anyway, after a month or so on the lees, we racked the whole lot. As you would expect, yeasts like the EC-1118 were done long before then but the RX212 was just tuckering out.

On 29 August, after a couple more rackings, we bottled the mead. Each mead was bottled in six 375 mL bottles and one 750 mL bottle. We're a little short on the 71B-1122 due to a failed experiment with a pump (really a waste of time on 1G batches, but fun!) and some sloppy bottle handling on my part. I think we still have about four 375 mL bottles of it though. Below is a chart of the finished results. The results for #12 (RC212) may be a little off. It kind of slipped through the cracks at bottling time so wasn't measured until tasting. I didn't have my thermometer, but it was 'Room Temperature' when the reading was taken.

The original plan was to occupy a conferance room late one Friday night and have an informal tasting. This was starting to sound a little wierd (it's probably against a great number of regulations and maybe even a few laws) so we had to find a new place. Luckily our friend Ken volunteered his house for the tasting. You rock Ken.

With the plans changing daily, I dropped a line out on the Mead Lovers Digest to see if anyone would be interested with all of one week's notice. I got only one response (in the area), but for two people, so that worked out well. The day of the event, the whole area (except Ken's place) had a blackout so we had to make last minute changes to the food delivery plans, but the resulting pizza was really good.

At about 8:00pm, everyone had trickled in and some even brought mead. Below on the left you can see the usual suspects. From left to right, we have Homesteader Ken, Little-Bro Steve, Darn-Right-This-Tastes-Like-Water-I'll-Have-Another Prashant, Just-SmellySmelling Brad, This-Guy-Knows-Wine Ian, Co-Cospirator Brian. From the MLD, we were privileged to be joined by Eric and Li (back centre of the right photo). I handed out blank index cards to all, and we began.

Alright, we might have begun before quite everyone got there, but everyone showed up before the first sample was done.

The next one of these I do, I'm going to make up some standard judging cards of some sort. Some of the comments were quite helpfull, where others (and I'm not naming names) held cryptic messages like: "4.+ 3++". I've tried to decode them as best I can. Also, we din't exactly taste them in numerical order. UPDATE: I've changed the list order below to match the order in which we tasted the mead. I think this makes us look a little more coherent.

No. Comments
10. I had never used (or even heard of) this yeast before. Apperantly it is a very aggressive yeast along the lines of EC-1118. It sure lived up to that. Comments:
  • Flowery, light honey flavor.
  • Fruity apple flavor.
  • Has a strong flowery taste. Strong alcohol smell. Mild on the buzz.
  • Doodle of a circle.
  • Powerfull alcohol smell. Ian's dizzy already.
  • Bitter!
  • Lightly fruity.
8. This was the second mead tasted. It was widely regarded as being much worse than the first one. In the end, this one was rated among the lowest. Maybe it will improve, but there's not much flavour to start with. Everyone seemed to think is was a little fruity though. Comments:
  • Fairly flat.
  • Fizzy, fruity nose, bitter.
  • A lot fruitier than #10 [Lalvin 43]
  • A bit better +
  • Fruitier. Very young. Plain.
  • Bitter, but less than #10 [Lalvin 43].
  • Light. Not a strong taste but a little fruity.
9. This one was the sweetest mead from a wine yeast and everyone seemed to notice. It could probably do with a little age. Comments:
  • ?Gworkbraun? [I think this is supposed to be a type of wine, but I can't read the writing]
  • Less nose, less flavour.
  • Sweet.
  • Bit worse - [followed by a long, loopy line]
  • Sweeter than #8 [Lalvin D47]. Quick flavour. No aftertaste at all.
  • Fruity. Buttery. Sweet.
  • Sweet light taste. A bit watery.
11. This one wasn't bad at all. It's interesting to see the comments start to diverge at bit at this (our 4th sample). Everyone agreed on the fruity aroma but the impressions of the tastes were quite different. Some liked it, some thought it was too plain. Everyone agreed that it was light, but we seemed to be split as to whether that was a good thing. Comments:
  • Plain. Not much taste.
  • Strong floral aroma.
  • A good aftertaste.
  • + +
  • Strong aroma. Floral.
  • Light and fruity.
  • Light fruity taste all the way through.
12. This was really the star of the show. Everyone agreed that it was by far the best. After much grumbling about whether this one would ever finish fermenting (even well into secondary) it really impresed us. Even the hydrometer test tube was empty by the end of the night (and, yes it was still good :). Comments:
  • Nice flavour. Full taste.
  • Surprisingly gently. Smooth finish.
  • Tastes better.
  • + + +
  • Warm and smooth.
  • Light and fruity. Smoothest.
  • Full flavoured. Smooth and fruity.
7. This one caught me off guard as I only added it to the list to contrast against the wine yeasts. It's was very fizzy and the only one I was really worried about blowing up in the bottle. Indeed, it was hard to keep the siphon going when bottling it was letting off that much gas. Everyone really liked it too. With a FG ov 1.042 (7.4% ABV) it was tied (With the other ale yeast) for the sweetest and rivaled #12 (RC212) for first place. I'm definatly going to have to try this one again. Comments:
  • Champage sweet.
  • Very fizzy. Champage-esque.
  • Smells good. Loved it -- best.
  • + + + Fizzy Nice
  • Fizzy, sweet with an edge. Light.
  • Sweet/Bubble/Smooth.
  • Sweet and fizzy. Taste all the way through.
6. This one was a slow starter and seemed to benifit the most from agitation during primary. However, it was probably the #3 top pick. It should be notes that at this point some of the notes start to get harder to read. Comments:
  • Pinot Noir taste.
  • Acidic. Yielding rich flavour. Mild floral aroma. Not bad.
  • Couldn't tell the difference. Getting drunk. [ed: Maybe]
  • + +
  • Acidic but balanced. Strong.
  • Bitter -- Strong.
  • Most of the taste is at the end but still good. Light.
5. While none of the meads were really horrible, some were not that good at all. This one wasn't so hot. It was a taste that kind of snuck up one you... then would knock you upside the head with a black jack and leave you for dead. On the other hand it sure fermented fast. Comments:
  • [Pair of 7's or ?'s]
  • Mild fruity nose. No taste. Watery. Bad after taste.
  • bad after taste.
  • [A scribble that might be a 'p']
  • Sweeter. Slick. Strong. Nothing, then an after taste -- Yeow!
  • Bitter.
  • Not very good. Bad after taste. Strong smell.
4. This was the 'other ale yeast' in the experiment. It was also the only liquid yeast. I really thought that it would finish with a lower gravity than it did but it never really got going. It seemed to have a confusing taste and smell. Not really a wine, mead or beer. Didn't really make a good impression. We'll have to see how this one ages. Comments:
  • Franzia Bros?
  • Very fizzy. Still sweet. Bitter after taste.
  • Fizzy!
  • +
  • Fizzy... odd taste.
  • Bubbly/Bland
  • Fizzy taste but short.
3. The comment cards are getting very hard to read at this point. The K1-V1116 produced a (wait for it) very dry and strong mead. There's still some sugar and flavour left. Maybe it will improve with age. Comments:
  • ?? [Definatly two ?'s this time]
  • Classic young mead [smeared] smell and flavour.
  • Watery.
  • + +
  • Strong. Bland.
  • Strong alcohol flavour.
  • Taste [smudged] ?tannin?. The end is fruity. [ed: Words of Wisdom]
2. Ah, EC-1118. It's like the Green Baretts, the A-Team and the Ghost Busters all rolled into one... and made out of yeast. Opinions were split on this one, but most agreed that it was at best middle of the pack. I think it would have done better with a higher OG. Comments:
  • WAY 2 LIGHT.
  • Same young mead [something]. Light. Bland. Hot.
  • Too druuk to tell. [ed: ...but in good company]
  • High A [ed: A == Alcohol?]
  • Light taste. No after taste. Strong!
  • Light/Bitter.
  • Light. Not a lot of taste, but not bad.
1. Next time I'll play with the order and sample size a bit. This one, being last, didn't get the attention it needed. The movie was already starting in the living room and one person, who may or may not be the person typing this was trying to steal the last of the #12 from the kitchen counter. Comments:
  • Bland and alcoholic.
  • Smells sweet/fruity. 71-B1122, eh? [ed: I swear this wasn't me]
  • Way to drunkt to totdlt. [ed: lucky it was the last one then]
  • + +
  • Last seen pouring the hydrometer test tube full of #12 into his glass.
  • Bland.
  • Medium taste more towards the end.

I've tried to make the most sense of the cards that I can. Some of them look like they may have run into some mead but I can still make them out. Any spelling errors in the above table are probably all my doing. Oh, sorry for changing everyone's "flavors" into "flavours" but I didn't notice until near the end.

As you can imagine, I still have quite a lot of mead left. We've agreed to meet again in about 6 months for the one year tasting. The date is (tentativly) set for the 15th or 16th of April, 2005. Just after taxes...



Nothing to see here.
