230 blenders active in and around Brussels § 1870: Analysis on Lambic’s wild yeasts by Max Rees (Germany) § 1891: first research on Lambic and Geuze by Belgian Professor H. Van Laer § Discription of Torula yeasts in Lambic. The name changed to Brettanomyces in 1904 when Claussen discovered this yeast in English stock-ale.
Van Lear § Young Lambic contains considerable amounts of lactic acid. While lambic is ageing, the level of lactic acid decreases while esters are formed. § Prof. Van Laer: “What confirms this vision, is that lambics containing low levels of acids, and most important, few acetic acid are the most esteemed, because of the taste and the perfume.”
HL spontaneous, 92% is sold as cask conditioned lambic and faro, 8% of this is bottle conditioned Geuze § World War I: 1914-1918 § Destruction of all copper brewing equipment § +/- 800,000 casks of Lambic in stock in 1914 § +/- 100,000 empty casks left in 1918
good bottle of Geuze § Hop Aroma & Flavor: Not to be perceived to very low, aged hops enhance the complexity of the taste. § Bitterness: no alpha bitterness, only oxidized beta bitterness § Wood influence : some vanilla, some spicyness and body from oak casks can be present moderately. The use of more or less new casks is a tool for the blender
good bottle of Geuze § Spontaneous Fermentation : § intense fruity-estery, moderately sour, and acidic aromas and flavors are typical. § horsey, leathery and phenolic aromas and flavors derived from Brettanomyces yeast be are present at very moderate levels. § some goaty bitterness is accepted, but fatty acids C6–C10 should be well esterified to grapefruit and citrus-like aromas. § taste may be very dry and are characterized by intense white wine-like flavors.
good bottle of Geuze § Carbonation should be 6,5>9 g/lit CO2 § Body: No body from residual sugars, but well- structured body from other components, with a dry mouthfeel. § Traditional Geuze has an apparent attenuation between +/- 90 and 100 %. § No sweetness either from malt, sugar or other sweeteners is present, although alcohol, esters and oak components can give a warming, sweet suggestion.
be avoided § Old hop character: tastes and smells like ripe cheese. § Diacetyl: should not be present and to be reduced by bottle refermentation. § High levels of lactic and/or butyric acid (tastes like sour butter, smells like dairy) § Perceivable acetic acid (vinegar). § High levels of ethyl acetate and acetone (smells like solvents) § Horse sweat. “Nose” should be clean, no 4 EP and H2S should dominate the aroma § Goaty and waxy aromas and flavors (from too large amounts of young lambic in the blend) § Phenolic aromas reminding burnt rubber (e.g. from bacteria while brewing in the summer season). § Lack of carbonation: bottle refermentation should result in 6,5 > 9 g/lit CO2 § Floating particles in the bottle: the sediment should stick well on the bottom of the bottle § Cork taste or moldy taste from unclean casks
