* '''Barley wine or wine extraction''' Wine can also be used as a method of extraction and preserving herbs. White wines are more often used traditionally due to the high tannin content of red wine, which may interfere with alkaloid rich herbs. Wine extraction may also be adapted to imperial or high gravity beer samples, such as using a barleywine, for steeping high volumes of herbs in the beer and then dosing the extraction back to larger batches later. If using this method, consider the influence of the solvent, which has its own flavor, along with the flavor of the herbs or spices you are using. This method is also not recommended if you need to maintain a certain ABV.
* '''Cold pressing'''- Cold pressing is similar to a French press in mechanics, but using cold water for extraction. Using sterile water, such as boiled and cooled water, is recommended. 2-24 hours maceration of solids is often needed for this method. Cold extraction allows for retention of volatile compounds that would be lost by extraction methods involving heat. This is especially true if this method is used after or near the end of fermentation so that volatile compounds are not lost during fermentation<ref>Von Seitz Theoreticales Brewery. theoreticales.com.</ref>.
