L‑Malic acid is a cornerstone in the art and science of winemaking. As one of the primary organic acids in grapes—alongside tartaric—it profoundly influences taste, freshness, stability, and microbial health throughout fermentation.
Measuring L‑Malic acid aids in determining grape ripeness at harvest and in tracking malolactic fermentation, where it’s enzymatically converted to softer lactic acid—reducing sharpness while enhancing mouthfeel, complexity, and microbial stability. Precise testing ensures malolactic fermentation proceeds as intended, avoiding off‑flavors and unwanted fermentations post‑bottling. In short, L‑Malic acid testing is essential for crafting balanced, stable, and flavorful wines.
For crucial detection below 0.1 g/L, consider using the rAPID-T System from Astoria-Pacific. The rAPID-T allows the operator to monitor a variety of specific tests vs panelized data. This affordable workhorse will become an invaluable tool in your laboratory.
As wineries scale their operations, the pressure to maintain quality while meeting production timelines grows exponentially. For wineries producing anywhere from 3,000 to 300,000 cases annually, routine analyses—like sulfites and volatile acidity—can quickly overwhelm a manual testing workflow.
The Need for Speed and Accuracy
Timely and accurate data is the foundation of high-quality winemaking. Critical tests such as sulfite levels and volatile acidity help winemakers make immediate decisions that impact the stability, taste, and longevity of their wines. Manual testing, however, is time-consuming and prone to inconsistencies—risks that increase significantly during high-volume production periods.
Automation: The Smart Solution
Astoria-Pacific’s automated wine analyzers, including the rAPID-T and Astoria2, are designed to alleviate the burden of manual testing by streamlining routine analyses. These systems deliver precise, repeatable results for sulfite and volatile acid concentrations—giving winemakers confidence in their data while freeing up lab staff for higher-value tasks.
Scalable Solutions for Growing Wineries
Whether you're bottling 3,000 cases a year or pushing into six-figure territory, automated testing solutions scale with your operation. Instead of relying on manual wet chemistry or off-site labs, Astoria-Pacific’s customizable analyzers allow you to bring efficient, real-time analysis in-house—helping you stay ahead of bottlenecks and ensure consistency across every lot.

The Astoria2 for Free and Total Sulfite analysis is a workhorse for laboratories with high sample loads.
Unlike other instruments, the Astoria2 does not use carcinogenetic reagents for the sulfite methods. It uses easy-to-use software on WIN10 or WIN11 and runs at up to 120 tests per hour.
Please note that the Astoria2 is designed for labs with lots of samples, so make sure to do appropriate cost analysis prior to purchase. We are happy to assist you with this endeavor.
The rAPID-T is an affordable system. Choose when you want to run different tests on your time. Automate core tests such as Acetic Acid, Glucose+Fructose, Free Sulfite, L-Malic Acid, NOPA, Ammonia, Total Sulfite.

Need a little help with your wine analyses?
Astoria-Pacific offers a very affordable system for the automated analysis of Acetic Acid, Glucose+Fructose, Malic Acid, Total Sulfites, Ammonia and NOPA. We understand that trying to analyze these tests manually and/or using handheld devices start becoming impractical for many wineries as they grow ... and, truthfully, there is also significant "sticker shock" when trying to look for other automated solutions.
Therefore, trust in us to provide you with the most affordable analyzer for these core tests in the wine industry. Also, benefit from driving your costs down from $4 - $7 per test to ~$0.50 - $0.70 per test via automation...
Hmmm ... do you have an FT-IR but still need a way to it calibrate every year? An inexpensive rAPID-T can do that and also be that additional layer of testing when your wine nears completion.
Astoria-Pacific ... yes, we're obviously trying to sell you something ... but we're also trying to help with sound, reliable chemistry...

Raymond Pavitt established Astoria-Pacific, Inc., in 1990. Its headquarters is located in Clackamas, Oregon (a suburb of Portland). Astoria-Pacific is the sole manufacturer of the Astoria and Astoria 2 continuous flow analyzers.
Astoria-Pacific started small, with a few offerings in the horticultural market. Its primary product was a liquid rooting concentrate, Dip'N Grow, for woody plant propagation.
The company later expanded into the automated chemistry and analyzer business by buying back the manufacturing rights of the RFA(TM) 300, which Ray brought to market in the '80s while at ALPKEM.
Astoria-Pacific's Research and Development team updated the modules of the RFA and integrated them with our powerful FASPacII software platform, which gave rise to the Astoria and Astoria2 analyzers.
Today, Dip'N Grow and Astoria-Pacific have become successful individual entities, and Astoria-Pacific has grown significantly to offer a wide variety of automated wet chemistry analyzers--both segmented flow and discrete--for several markets.
Our goal is to provide our customers with the best products and support in the industry.
