Pushing my Wild Saccharomyces

For anyone who has read a few posts on here you probably have noticed my enthusiasm about a wild yeast I harvested this past summer. See hereherehere and here. This brew will be more of a test to see how this yeast preform in higher gravity and ABV beers. As the Gildemeester ale yeast seems to usually have an apparent attenuation of ~95% the OG will not need to be super high.

Last Brew day

Was an absolute crazy mess but I ended up with 17.3 gal and trying my first cold sparge. My noticeable Pros/Cons. Pros: Little effort, mash tun cooled down fast and was easy to clean because of it. Cons: undershot efficiency by 4% which is pretty big for me. Instead of my 1.045-1.049 range I hit 1.040. Nothing I cannot work with though. After all this will be a dry sour!

Gildemeester Melon Head Ale Review

16976898_10154861139005336_670187444_n

Appearance:
Mandarin orange colour, moderately hazy (chill haze from bottle conditioning be damned). Pours a thick white fluffy head that persists. Laces the glass with each sip. Becomes crystal clear as it warms.

Aroma:
Pear, melon, field berries, banana, clove, black pepper. Ester, phenols and hop aromatics are well balanced. A complimentary note of honey from the malt shows up in the background. This pen I am wringing with (originally) is rather solvent-y. Ball point from now on.

Mouthfeel:
Soft and silky. Moderately high carbonation level with a medium body. Surprising for finishing at 1.003. Very elegant feeling.

Flavour:
Melon, clove and black pepper up front. Mild honey and bready note in the background. Light tangerine and mild herbal notes. Tastes the way a wild strawberry patch smells if that makes sense. Bubble gum starts to come into play as it warms.

Overall Impression:
Easy drinking and rather refreshing. A mildly tweeted version is due for this summer I believe. More dry hops are needed. After a full 12 oz bottle and waiting for dinner you can tell this is a bit higher ABV than your standard beer (6.6 ABV) although the flavour would never let you know.

Next Time:
Double the flame out and dry hops. Hell maybe triple. Extended 1 week cold crash to try and clear the chill haze.

Cheers,
MD
