ALDC – 1 kg

Alpha Acetolactate Decarboxylase (ALDC) prevents the formation of diacetyl by breaking down the precursor, alpha acetolactate, as it is formed during fermentation – converting it quickly and directly into acetoin.

ALDC – Alpha Acetolactate Decarboxylase (ALDC) prevents the formation of diacetyl by breaking down the precursor, alpha acetolactate, as it is formed during fermentation – converting it quickly and directly into acetoin. Since diacetyl can be formed from the precursor in the finished package, adequate removal helps ensure the product retains the intended quality.

ALDC can also help to reduce the rate limiting step in conditioning. Only 1 to 5 grams per barrel is required to be added to cold wort, prior to yeast pitching. As this enzyme is pH sensitive it is deactivated by the normal pH drop at the end of fermentation

ALDC Technical Information Sheet

We brew a lot of lager. Not having to worry about doing a diacetyl rest, using ALDC can shave a brew week off the turnaround time on a lager. If we can save time without sacrificing quality, we’re going to explore it. It’s also a peace of mind thing. There’s peace of mind in knowing your beer might sit on the shelf and it won’t degrade in flavor quality during that time. It’s important to us that the beer tastes the way we intended it to. The cost of a little jug of ALDC is well worth the price if it prevents us from dumping beer down the road. Our American Ale yeast strain tends to throw off a little more diacetyl than our hazy does. But hop creep is a huge issue when you’re dealing with high hop charges. You can take steps to mitigate it without ALDC. Sometimes it works. Sometimes it doesn’t. I’d rather use the thing that 100 percent works. You don’t want to buy those beers back off the shelf because you’re hearing reports about diacetyl or another issue – it’s worth using a product like ALDC to mitigate some of those weird things that can happen after your beer leaves the tank and is out of your hands.
