Kombucha mother is all growns up


Started the kombucha culture on January8th...just like in culturing yeast from the dregs of a bottle conditioned beer, it takes a bit of time to get going. I'd say I had a cohesive mother formed after stepping up three times, increasing the volume (and container) each time. I leave her covered with a tea towel (took it off for the picture). its kinda funky looking, but I suppose I would expect it to be. The bacteria are pumping out some serious acids...I haven't taken a pH reading, but it stings the nostrils ...in a good way.

Now that the mother looks big enough, I made ~1 gallon of sweetened green tea, dumped out most of the liquid (pungent stuff), and now have what will be my first kombucha fermenting now. I plan to juice some fresh ginger and lemon to add along with a bit of priming sugar at bottling time. that should be sometime this weekend.

Belgian IPA

Bottled yesterday, 17Feb2009, FG 1.002...how low can you go? a taste of the gravity sample revealed just what I had expected...very dry, very hoppy, now quite concerned that there'll be little to no malt backbone. why are my FGs completely all over the map?
a tasting update will be next, once adequately carbonated.

Houblon Chouffe...fantastic hybrid style.
I wanted to see if I could brew an DIPA with the complex belgian yeast flavor that can satisfy both the hop head and the belgian fanatic in me. I really want the ale to develop that distinct and beautiful meringue like head. I plan on getting a descent CO2 volume on this, and bottle conditioning it in some of my larger format champagne bottles, to get proof of concept (get consistent CO2 across the various bottles + proper sealing via corks). I feel confident that the yeast and hops should produce the head I'm seeking. The recipe should provide an american hop characteristic, but these citrusy and piney flavors should play a backup role (if at all possible) as I actually wanted the majority of the hop profile to be noble. I wanted sufficient bitterness, but really just enough to balance the aroma and hop flavor. Dry hopping as described below will round out the noble hop aromas.
The grist of the ample base malt (Belgian pilsener) should form a clean canvas for the belgian specialty grains to play off. My first attempt at a tripel proved to be a bit too sweet, due to the high FG as a result of the extract used. In this go, the sucrose (in addition to a loose mash with low-ish temp of ~148, at a lengthy 1.5 hours) will drive the FG down to dry levels. The specialty grains will provide a touch of toasty/biscuit to the malt profile.
the yeast starter was stepped up several times, and I would take a noseful of the belgian yeast.
I plan to drink the majority of this batch very young to appreciate the full hop profile. I wish the LHBS had the 3522 (achoufe yeast). But, the nose tells me the 1214 (chimay) is producing an excellent ester profile that shouts belgian.
