After the never ending battle between the hop heads and sour lovers we decided to appease the two. Using Nelson Sauvin from New Zealand and Citra from the Pacific North West this mixed fermentation brew is juicy, sour and extremely refreshing. Sour & hops in perfect, thirst quenching, melody!

Admin Note: Formerly known as Mash Up the Jam. Name change to Jam Up the Mash announced in August 2018 due another beer in the market with a similar name.

Reviewed from notes.
Can to tulip.
Appearance: golden copper with a finger and a half's worth of white foamy head which dissipated nicely to leave some light lace
Aroma: lemon sweet and tart tones, some berry tart and sweet tones, noticeable lacto, subtle grassy sweetness, light tropical fruitiness
Flavor: combines the prior noted aromas to a sour to tart aspect up front then some light sweetnes shows up underneath; finishes sour to tart lemons & berries
Texture: light to medium bodied, leaning towards being a sipper, some of the tart & sour becomes slightly assertive but doesn't really become a puckering problem
Overall: nice enough sour ale, I think I could come back to and if I did I bet this would be nice to end a night on.

Second round for this beer, best before 06/25, at Amstein. Drinking it tonight relax after a busy between aligro, hornbach and to swim. Good and tasty sour beer, typical sour note and yeast, clear citra hop, dry and mineral, subtle dry raspberry note.

Color amarillo dorado claro, velado y muy atractivo, bajo una fina capa de espuma blanca. Aroma y sabor fresco , lupulado, ligeramente herbal con toques de ácido láctico y cítricos. Dulzor leve, acidez moderada, escaso amargor, final seco y lupulado. Tanto sabor como aroma mejoran notablemente con el atemperado. Muy rica

Tap at Hopa. Golden pour, white head. Nose is citric, lightly resinous hops, citrus zest, faint lactic touch. Taste is light to moderate sour notes, lactic and there's citrus zest again, a touch of bitterness. Closes with bitter, tart finish, has ligt body and soft to average carbonation.

Can from the lcbo. Light lactic notes, sour cereals, light citrus. Carb is soft, mouthfeel thin. Finish is tart, watery, light fruit. A big meh.

Can from Beer Republic. Aroma is citrussy with strong lemon, lacto, some hop and tropical notes, wheaty pale malt. Flavour is tart and mild sour with a light hoppy bitterness. Body is medium. Pretty lemony, lacto sourness, not my favourite profile by a long shot but this comes together pretty well.

16 oz can. Aroma shows white white mixed with lactic acid. Flavor of stale bread, white grapes, and acidic citrus. Bolder sour finish. I guess it is about what you would expect for the style.
