Un Poquito Wylde Tasting

Now that my kegerator is fully operational again, and this keg is fully carbed, I can finally get around to tasting the micro saison I made with my local wild yeast. If you remember the grist was simple, half Vienna malt and half white wheat malt for an OG of 1.032.

For such a simple and small beer this thing has a lot going on. I think it's really cool to make a beer that is completely unique to your area. Unfortunately that's a hard thing to do here in South Texas where mold runs rampant most of the year. I probably tried harvesting yeast 5 or 6 times before I got this last round to actually work without any sort of infectious mold. All in all the flavors of the yeast are relatively mild. Brett character mostly. If I decide to reuse the yeast (which I did wash and save in a growler) I expect some more lacto/pedio character to develop.

Appearance is a ruddy straw color. From the tap a one finger pristine white head forms. The head sticks around quite a bit, that's thanks to the wheat.The head is a little bit alive, with rocky chunks of foam forming and dissipating. Beer is quite cloudy, yeast was not very flocculant. Even with a week of cold crashing, I may decide to hit it with some finings..

The aroma is interesting to say the least. A bit of crackery malt, and a touch of Czech Saaz pokes through, then just awash from the yeast. Solid Brett character, pineapple and other non-descript tropical fruits first, followed by danky bretty must and funk.

The taste follows suit right along with the nose. A bit of Czech saaz character makes itself known up front then gets washed away with Brett character. Tropical notes of pineapple and mango dominate the palate followed by a slight bit of musty Brett funk. A light bit of lactic sourness hits the back of the palate. Finishes dry, but that's too be expected.

The mouthfeel is surprisingly full for such a small beer. The large amount of wheat really helped with that, but there's also a certain silkiness to it that I believe to be coming from the yeast... a lot like what you would get from a saison yeast. I carbed it only to 2.5 volumes to keep it from being astringent, but it's not quite lively enough. So I think I'll up the pressure for a couple of days to see how that helps.

Overall it's a great beer, that's nice and refreshing as it's getting hot out. I think I'm going to try to let it live in the kegerator for a month before I completely finish it. I'd like a bit more acidity to develop. This yeast is interesting and could play well for a larger beer.

Edit 4/26: Decided to throw an ounce of Czech Saaz into the keg. I'm loving the character of the beer so far, but would really like some more hop character.

Wild Yeast Micro-Saison

To continue with both my session beer kick and my funky brewing project this week I decided to brew with some local wild yeast that I harvested back in January. I wanted to brew something that would display the yeast quality well without too many other competing flavors. That's why I went with a very low ABV saison. I'm posting about this because for one I think it's really cool to gather your own yeast, but also because there's not really a lot of info available. The pic above is from when I propped it up. You can see the yeast cake on the bottom. The plastic ontop. Is because all of my airlocks were already in use.

I've tried harvesting wild yeast before but all I would get was mold and/or something that just smelled rank. Here in Texas the mold is pretty high so its not the best environment for catching wild yeast. What made this attempt different was that for one it was on one of the few cold nights we see in San Antonio, I've read that during colder weather the bugs are more at bay. I also made sure to wait for a night when the weather report listed the mold count as low/none.

I whipped up a weak dme sollution of 1.030(ish) and split it into two seperate mason jars. I covered them with a bit of cheesecloth to keep flies out and left them out overnight. One went out on my front porch and another on my back porch. Once brought in I covered them with plastic. I ignored it for a while, then before I knew it it had been a week. Checked it and... nada. Nothing had happened. After another 5 days one finally fermented with some nice little yeast rafts floating on top. Two days later the second followed suit. I decided to prop them up together with some late runnings from my lambic. I shook well, gave it nutrient etc... and nada. I decided to leave it alone and ended up forgetting about it. Two weeks had passed and I went to throw it out and sure enough there were yeast rafts on top and a cake on the bottom. I crash chilled it and left it. Then two nights ago I decanted it and threw in another round of starter wort, this time it took off in 12 hours.

When I decanted I took a sample. The smell was wonderful, very fruity with notes of lemongrass and peach plus a light spice. There was also a light sourness to the aroma and a bit of funk. The mouthfeel was quite silky and full. So perfect for a saison.

The brewday was very easy with a very small and simple grainbill. I went with a no sparge method to help accentuate the malt profile. The grainbill was simple, half Vienna half malted wheat. I chose both of those malts to help with the body/malt impression of the beer. The high percentage of wheat should make the mouthfeel reasonably full and the vienna malt should add a bit of breadiness to it. For hops I went with classic Czech Saaz, their spiciness should play well with the characters that I was picking up from the yeast. I only did a single 15 minute addition of the hops, depending on where this beer goes I may end up adding a dry hop addition.
