Cork taint is a musty off-flavour in wines mainly caused by 2,4,6-trichloroanisole, but other haloanisoles can contribute. In this work, a method for the extraction of 2,4,6-trichloroanisole, 2,4,6-tribromoanisole and 2,6-dichloroanisole has been developed. The procedure involves the extraction of the haloanisoles from cork by pressurised liquid extraction and the analysis of the extracts by both GC-@mECD and GC-MS-MS. A central composite design was used to investigate the dependence of the recoveries of the analytes on the temperature, percentage pentane-diethyl ether ratio and the extraction time. Experimental data were then processed by using the multiple regression analysis in order to calculate a mathematical model representing the relationship between factors and responses and to determine the best experimental conditions for PLE method. These conditions corresponded to a temperature of 176^oC, an extraction time between 2.8 and 4min and an 80:20 pentane:diethyl ether ratio.
Stream & Waterfall
The water is pumped through a filter and into the stream. I'll need to build a real waterfall, but this makeshift one is good enough for now.

They didn't manage to finish their packjobs in daylight, but that's not a problem a little headlamp can't solve ;)
