No, I haven't personally. But I'm not a huge proponent of LOX-free malt.

Sorry for the late reply; I just came back from holidays. Yes, there are a few. A few examples would be: Activity of Lipoxygenase Isoenzymes During Malting and Mashing (but speaks of 67 °C) System Changes in Wort Production for the Improvement of the Flavour Stability of Lager Beer (PhD thesis...

As a metal, copper is one of the best conductors of heat. It warms quickly, stays warm and distributes the heat evenly (so less risk of scalding and better control). It's why it's also popular in the kitchen. Besides that, it also looks gorgeous. In terms of oxidation, however, stainless steel...

'Beer stability' can generally be broken down into three categories: physical (which mainly affects clarity), microbiological (usually affected by spoilage or contamination) and flavour stability (the beer's ability to retain its original character). While it's true that microbial...

Adding antioxidants ‘Antioxidant’ is a term widely used, but surprisingly difficult to clearly define. A basic description would be that it is any substance that delays, prevents or removes oxidative damage. Antioxidants can do this in a number of ways, e.g. by quenching free radicals or other...

Limiting heat load during brewing As touched upon earlier, temperature is a huge driving force behind any chemical reaction, including those involved in the formation of off-flavours (Maillard and Strecker degradation reactions). Some of these created off-flavours are non-volatile and will...

Beer freshness is that what makes a good beer pop. Sadly enough, for both brewers and consumers alike, beer is unresistant to the tooth of time. Noticeable staling can already occur 2-3 months from packaging when stored at room temperature. As beer starts to fade, it loses precious aromas and...
