Tasting : Hidden Duck Hefe 2.0 (Hefeweizen)

As summer comes to an end, it's time for me to finally post the tasting notes to one of the finest summer beer styles out there: Hefeweizen. This was my third attempt at the style, and my first in several years. Basically a rebrew of my last recipe (same grist, same yeast), I brewed this beer in late June, bottled it in mid-July, and it's been tasting pretty great since. I bottled this beer instead of kegging it mainly because it's such a great style to have on hand for travelling purposes, what with going to a couple of family vacation spots back and forth all summer.

I'm no expert on Hefeweizen, but I really do enjoy a well-crafted one. I can't claim to have the most discerning palate, or nose for that matter, but I consider a good Hefeweizen to be well-balanced between clove and banana (if you get a bit of bubblegum or vanilla in there as well, that works) in both the flavor and aroma, with a little wheat character backing it all up. The color should be quite light, the body cloudy from rousing the yeast, and the beer should have a large, white, creamy head that has really good retention. Finish that off with a creamy (but not heavy) mouthfeel, and, importantly, high carbonation. You want this style to be refreshing.

So, I think in the end this came out really well. I believe I hit on all the important points I mentioned above (not really getting any vanilla or bubblegum in there, but that's ok). As I mentioned in the original post, this style of beer really shows how important process is, at least as much as recipe. Use a good yeast, make a starter, aerate the wort appropriately, and keep tight control on your fermentation temperatures, if you can.

I've got a few of these left (I've given quite a few away)... I'll definitely be drinking them as the warm weather unfortunately starts to fade!

Appearance: Poured with a very large, white, creamy thick head that shows fantastic retention. Body is golden-coloured, and cloudy. Effervescent.

Aroma: Nice balance of bananas and clove; I’d say the banana is a bit more prevalent than clove, but not by a lot. No real bubble gum aroma. Very slight background of wheat.

Taste: Again, comes across nicely balanced, with a bit of supporting wheat character. Very easy-drinking, low bitterness in the finish. No hop flavor.

Mouthfeel: High carbonation, medium-bodied and creamy.

Overall: Came out great, pretty much exactly what I was going for. Fantastic summer beer.

Brewing an El Dorado One-Hop Session IPA

Ever since my first foray into brewing a single-hop Mosaic Session IPA last November, I've really been anxious to try it all again, but with another hop variety. I really enjoyed what Mosaic brought to the table (such a fantastic hop), I liked how brewing solely with that hop really helped me identify what aroma and flavor characteristics it added to the beer, and on top of all that, I love a well-brewed Session IPA. I'm a huge fan of having a big hop presence without big alcohol... as long as it's done well. I've had some fantastic Session IPAs over the last year (it definitely seems to be one of the popular "styles" now for an increasing number of breweries), but I've had some disappointing ones, too. My only major complaint about my attempt with Mosaic was that the beer did come out a bit thin, so I hope to remedy that with another try... this time, featuring another fairly-new hop variety - El Dorado.

El Dorado became commercially available in 2010. Developed at CLS Farms in Washington state, it's a high alpha acid aroma/flavor hop variety that doesn't seem to have garnered as much popularity as some of the really big new hops, such as Mosaic, Nelson Sauvin, and Azacca. However, I had read some positive homebrewer notes about it online, with descriptions of tropical, citrus, and stone fruit, along with pear and, oddly enough, cherry or watermelon Jolly Ranchers (and this is from many sources). I had the opportunity a few months ago to buy a half-pound from the late-2013 crop, and couldn't resist (I'm very weak when it comes to buying hops). It looks like some breweries have tried brewing some beers with all El Dorado, such as Flying Dog, with an Imperial IPA in their Single-Hop series. Unfortunately, I have not tried any of these beers (aside: am I the only one that really despises Flying Dog's labels?).

Like I said, brewing a single-hop beer is a great way to feel out a new hop variety, but something you have to keep in mind is that brewing with one hop does not necessarily work out better than when you combine multiple hop varieties. I'm a big believer that adding too many hop varieties in one beer can easily result in a muddled mess, but there are plenty of beers out there that combine 2 or 3 varieties with better results than a similar beer with just one of the hops. But in this case, I really wanted to continue this experiment, and didn't have any other plans to use El Dorado in the near future, so I went with it. Just wanted to make clear that I understand the risk that comes with this... that is, brewing a beer solely with a hop that sometimes resembles Jolly Rancher candy.

For this recipe, I virtually duplicated the malt bill, but scaled it down to a 4-gallon batch. I thought this grist worked very well for the Mosaic Session IPA; it provided enough specialty malts to help bolster the body slightly, yet the beer didn't come out too malty or sweet. It had just enough malt character... mind you, yes, the beer was a bit too thin, so this time I went with a target mash temp of 153 F, compared to 149 F last time.

As for the hopping, with the Mosaic Session IPA I was worried after brewing it that maybe I had hopped it too-heavily, but I didn't find that to be the case when I finally tasted it. There was no heavy grassiness to the aroma or flavor at all; lots of hops, yes, but it was exactly what I was aiming for in that department. I made only a couple of slight changes this time around: same amounts, but I moved the 10-minute addition to 5 minutes, and steeped the flame-out hops for a shorter amount of time (10 minutes compared to 15 minutes). No real reason for these changes, I just wanted to try moving the hops a bit later, and felt a 10-minute steep would be enough for such a low-ABV beer (since you still get some bitterness when wort temp is above ~180 F).

Everything else is the same as well. Same yeast (US-05, going for neutral character here), same water adjustments (a bit of gypsum and calcium chloride added to the mash). The only big difference involves packaging; now that I have a kegging setup, I'm definitely going that route compared to bottling (as with the Mosaic Session IPA). Hopefully the keg-hopping and minimalized oxygen exposure to the hops (although to be honest, I still don't feel like I've perfected the procedure) will result in a really hop-fresh beer. Since I've started kegging, I haven't necessarily noticed a huge difference in this quality, but the hop freshness does last a lot longer compared to bottling.

If you happen to look up the recipe for my Mosaic Session IPA and compare it to the one below, note that this current batch is for 4 gallons, vs. the 5.5 gallons I typically have brewed in the past. This beer is currently carbing, so look for the tasting notes to follow soon. And once again, forgive me the lack of pictures in this post; summer is a distracting season, you know!

Yeast: US-05 Safale, rehydrated

Water: Fredericton city water, carbon-filtered; 3 g Gypsum and 2 g calcium chloride added to the mash

- Brewed on July 21st, 2014, by myself. 50-minute mash with 9 L of strike water, mashed in at 152 F, slightly below target temp of 153 F. Mashed-out for 10 minutes with 4 L of boiling water. Sparged with ~3.5 gallons of 168 F water for final volume of ~5.25 gallons.
- SG on target at 1.037. 60-minute boil. Flameout hops had a 10-minute steep before turning on the chiller. Final volume ~4 gallons. Chilled down to 68 F, then poured/filtered into Better Bottle. OG on target at 1.048. Aerated with 60 seconds of pure O2, pitched rehydrated yeast. Placed BB in laundry sink with some cold water to try to keep temp down.

- Vigorous airlock activity over the next few days; temp got as high as 72 F before finally settling down when active fermentation did.

- 30/7/14 - Racked to a CO2-purged keg, added dry-hops in a mesh bag and left at room temp.

- 6/8/14 - Removed dry-hops, set keg in keezer to bring temp down to the mid-40s before beginning to carb.

- 21/9/14 - Posted the tasting notes. Strong orange character to me; a very tasty Session IPA, but not a hop I would rush to use on its own again in the future.
